eclipse adt bundle installation [duplicate] - java

I just append
-vm
C:\Program Files\Java\jre6\bin\javaw.exe
in eclipse.ini then I try to start eclipse again and got this error. Give me how to solve or link that actually solve it.
this is my eclipse.ini
-startup

Thank you

I had the same error when configuring eclipse.ini to use JRE6. Turns out I caused this error by incorrectly configuring eclipse to use the 64 bit JVM while running a 32 bit version of eclipse 3.7.
The correct configuration required the eclipse.ini -vm argumument to use "C:/Program Files (x86)/" instead of "C:/Program Files/".
Make sure that the JVM version (32/64 bit) you use matches the eclipse version (32/64 bit).

It may just be the way the error shows (and not how it is written in the eclipse.ini file), but there is text in Eclipse.ini (Specifying the JVM) that says the following:
The -vm option and its value (the path) must be on separate lines.
The value must be the full absolute path to the Java executable, not just to the Java home directory.
The -vm option must occur before the -vmargs option, since everything after -vmargs is passed directly to the JVM

Look at the second line of the message box. There you can see which java runtime in fact is started. Mine was suddenly C:\ProgramData\Oracle\Java\javapath\javaw.exe. This happened after I have installed a "chrome java updater" (Chrome browser moaned: 'your java is outdated, you have to update...').
Before this "chrome java update" my eclipse (luna jee x64) started without error. Looking closer to the background I detected following: the chrome java updater (notabene started from an Oracle site) added C:\ProgramData\Oracle\Java\javapath in front of the env var PATH. It contains three symbolic links to the newest java 8 JRE installation in (x86) program folder -> hence to a 32 bit java JRE. Oracle replaces with Java8 the old technique having the symlinks in system32 (64bit) resp. SysWOW64 (32bit).
Meanwhile I learned. Whatever java installer you have executed last (the *.exe) leads windows to remember that java flavour (32b or 64b), with the result that after an update the links in C:\ProgramData\Oracle\Java\javapath point to a java installation of the remembered flavour. If you have a 64b eclipse installation and encounter the described error: just re-install the newest 64b JDK. After that the java updates do no more link to a 32b version. And eclipse 64b will start correctly without the entry in eclipse.ini .

You need to check if your PC has a 64-bit or 32-bit operating system, then same goes for your JDK (64-bit/32-bit) and also for Eclipse (64-bit/32-bit).
Make sure they are all the same; if not, you need to download the one that matches your bitness.

For Eclipse:
Added this two lines in eclipse.ini
Second line represents the JDK location of the javaw.exe file.
-vm
C:\Program Files\Java\jdk1.7.0_60\bin\javaw.exe
Note: place -vm lines before -vmargs, otherwise default location is taken.
For STS
Change the same as above in STS.ini

I just hit this too. Turns out that at least for me, this was due to trying to use a win64 version of the JRE with a win32 Eclipse. I seems that win32 Eclipse requires a win32 Java (what is called -586 in the list of Java installers from Oracle/Sun).
The reason I was using both is that I was trying to pinpoint a bug that only manifested itself in 64-bit Eclipse, so I needed a 32-bit to compare to.
Once I installed BOTH the "x64" (win64) and "i586" (win32) versions of the JRE on my machine, things work fine and no error 13. You can apparently have both installed at the same time.

The error means it's the wrong JVM version for that version of Eclipse. The link has more details:
http://www.ehow.com/how_4784069_terminated-exit-code-error-eclipse.html

Make sure the Eclipse and the Java that you are using are both either 32-bit or 64-bit.
You cannot run 64-bit eclipse with 32-bit JRE.
java -version
Java HotSpot(TM) 64-Bit Server VM
The 32 bit version JRE will not have 64-Bit in it.

I just had the same issue, and spend about an hour trying to solve the problem.
In the end it was a '#' character in the path.
So I renamed "C:\# IDE\eclipse 3.7\" to "C:\+ IDE\eclipse 3.7\" and that solved the problem.

Recently I faced same issue.My version of eclipse didnt support java version 8.
I had accidently installed jre 8 on my machine which automatically updated my PATH variable by appending "C:\ProgramData\Oracle\Java\javapath" in the beginging which led eclipse to pick up this version(and ignore the manually added 1.6 version which came later in order)and crash with exit code 13.
I just removed this string from the path so which led system to pick up my older version and eclipse started just fine.

I had the same issue with eclipse in my both machine. I had jre 32 bit installed. So I removed 32 bit and installed 64 bit instead and it worked perfectly.

simply install 64 bit version of JAVA from http://java.com/en/download/manual.jsp
and uninstall older version if prompted by the 64 bit installer

Go to the folder where you saved Eclipse. Look in the configuration folder at the startup log. It will give you a much better diagnostic than "exit code 13".

After java update, eclipse will not start because default jdk location has changed. Adding the following lines to eclipse.ini file solved my problem immediately:
-vm
C:\Program Files (x86)\Java\jdk1.7.0_75\bin\javaw.exe
I added these lines just before vmargs. It looks like as the following :
...
--launcher.defaultAction
openFile
-vm
C:\Program Files (x86)\Java\jdk1.7.0_75\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Dhelp.lucene.tokenizer=standard
-Xms40m
-Xmx512m
For more information on eclipse.ini, visit this the site http://wiki.eclipse.org/Eclipse.ini#-vm_value:_Windows_Example
In my case, i use 32 bit eclipse and java. If you installed both 32 bit and 64 bit versions of java, be careful to choose the right version. For 64 bit versions, refer to the javaw.exe file under the directory
C:\Program Files\Java\jdk1.8.0_60\bin

Whenever you see this error, go to Configuration directory and check for a log file generated just now. It should have proper Exception stacktrace. Mine was a case where I got an updated 32-bit JRE (or JVM) installed which was the default Java that got added to the Path. And my Eclipse installation was 64-bit which meant it needed a 64-bit VM to run its native SWT libraries. So I simply uninstalled the 32-bit JVM and replaced it with a 64-bit JVM.
I wonder if they will improve this reporting mechanism, instead of silently generating a log file in some directory.

This error occurred to me on ubuntu, having installed 32bit and 64bit java. Use
sudo update-alternatives --config java
to set the right version to use as default.

Just uninstalled jre-32 bit version and It worked fine for me.

I was using Eclipse Juno and I didn't remember if it was 32 or 64 bits. I installed Java 32 bits and that's why it failed. I then installed Java 64 bits and Eclipse Juno is working again.
I also removed any java or jre reference in my environment variables (PATH).

In my opinion the most answers here regarding different architectures of Eclipse and Java are simply wrong and this can be easily checked using e.g. Process Monitor under Windows. The -vm option is there to run a specific version of java and the point of it is, that the configured process is started and runs all the Java code on its own, that's why you configure up to java.exe. In that case you DON'T need to have the same architecture for Eclipse and Java, but can happily mix both 32 Bit and 64 Bit. You only CAN'T mix both, if you DON'T use -vm, but let Eclipse load Java natively into its own process using jvm.dll and such. That latter behavior is Eclipse's default, but not the case anymore if you properly configure -vm in eclipse.ini.
If you don't believe me, do some tests on your own using different architectures of Eclipse and Java and do configure -vm or not properly. In the end, that's exactly what the questioner described in his comment to the accepted answer:
Cannot run Eclipse; JVM terminated. Exit code=13
He is telling that a 64 Bit JDK is working now, but in his screenshot one can see that his Eclipse is 32 Bit, because the path for launcher.library is 32 Bit.
And now for the reason I came here: Ony of my customers had some problems loading one of our Eclipse/OSGI based applications as well and Java exited with exit code 13. In the end it showed that the problem was not about -vm or the architectures of Java and eclipse.exe, but instead he was simply missing config.ini and I guess eclipse.exe wasn't aware what to load or such. After we recognized that and put a config.iniback in place, the app loaded fine with using -vm and a 64 Bit JRE7 in combination with a 32 Bit eclipse.exe.

I had the same issue on Ubuntu, and solved it by unpack all *.pack files in jdk directory.
for example:
cd /usr/java/jdk1.7.0_03/jre/lib
sudo ../bin/unpack200 rt.pack rt.jar

use the configuration below;
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20130807-1835

-Xms40m
-Xmx768m
-XX:MaxPermSize=256m
-Dorg.eclipse.swt.browser.IEVersion=10001

I fixed it reinstalling the jdk. In my case it was necessary to do:
java -version
sudo apt-get purge openjdk*
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
java -version
javac -version
taken from Install Java JDK+JRE (oracle) in Kubuntu 13.04 from apt

In my case JAVA path was not set in Env variables. Started to work after correct path was set in Env PATH.
Type javac in command prompt and make sure JAVA PATH is correct.

I did couple of things inorder to get rid of this annoying error as modifying .ini never worked for me.
Installed latest JDK
Delete old eclipse IDE folder completely.
This time i Unziped to different location
Double Click "eclipse.exe" Works now like charm
Use default workspace to load your old projects.
Am suspecting it to be JDK's Java VM issue more than eclipse.

I used the new Eclipse Installer. I didn't like the installation path and I changed it manually. After that, I got the exit code=13 message too.
There is a new property in the eclipse.ini file named -install. I just had to modify it with the new location, and that solved this issue.
In the new installer I selected D:/eclipse, but the IDE was installed at D:/eclipse/eclipse. So, I moved the folder manually. The next time I tried to open eclipse I got the exit error. Thus, I had to modify eclipse.ini and set the current location:
-install
D:/eclipse

Before going to the solution, let us know why it is showing that error. If you know the problem behind this issue we can easily fix that error.
Reason 1: The most common reason behind this problem is, we are trying to install different bit version-that is, 64 bit or 32 bit version of the software. It maybe either Eclipse or Java.
Solution:
Check which version of operating system you are running.make sure you downloaded the same version of Eclipse as well as same version of Java software.
Reason 2: Configuration mistake in Eclipse.ini file
Solution:
Add this line "-vm then path of your java sdk" at the end of Eclipse.ini file. for example:
-vm
C:\Program Files\Java\jdk1.7.0_71\bin\javaw.exe
Reason 3: Special characters ( #, !, #) in Eclipse installation directory.
Solution:
Make sure you don’t have any special characters.
Reason 4: You have added JAVA path two times in PATH system variable and both the path are different.
Solution:
Remove one incorrect/different JAVA path from PATH system variable.
Reason 5: You maybe using latest version of Eclipse, but you might be using wrong version or unsupported version of Java Virtual Machine (JVM).
Solution:
To check which version of java you are using open command prompt by pressing win+R key and type cmd and press enter. Now in that console type Java -version command to know java version.
Now research whether eclipse support that version or not.
Or
You can open “readme” folder in Eclipse folder and open readme_eclipse.html to see which version it supports.

for ones with Eclipse Neon
I wanted to run Eclipse Neon and had JRE 1.8 but JDK 1.7
It returned error=13
then I installed java JDK 1.8 and everything worked like a charm

I had this issue also. I had an old JDK1.8.0_05. I installed the newest JDK1.8.0_111 and everything works great now. Just be sure to update your environment variable.
I am on Windows 7 64 bit.
Using Eclipse Neon 1a.
Hope that helps someone.

I face same issue with sts 3.8.4, so I tried different settings but not luck,
I reinstall jdk again n tried but same problem.
Finally I downloaded sts 3.8.2 n it runs with out any issue.
Using windows 8, 64 bit os.
thanks

This can happen when the PATH environment variable is point to a wrong java instalation.

Eclipse and Java SDK [duplicate]

I am using Eclipse for developing BlackBerry Applications. I have JDK/JRE 7 currently on my computer, but that makes the BlackBerry plugins crash. Actually is a known issue and the only thing need to be done is run Eclipse with JDK/JRE 6 instead of 7.
I downloaded and installed version 6. However I am pretty sure Eclipse still uses 7. I had the same problem a year ago and I remembered I had to configure some System Variables and it worked, but I can't really find the solution now.
Any idea on this one? Important! I don't want to compile in version 6, which means I just have to choose the Java version through Eclipse. What I need is Eclipse to start with version 6.

Open eclipse config file eclipse.ini in your Eclipse folder.
Add -vm yourPath\Java\jre6\bin\javaw.exe like:
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120522-1813
-product
org.eclipse.epp.package.java.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-vm
C:\Java\jre6\bin\javaw.exe
...
If the path contains spaces there is no need to escape them, see the Eclipse Wiki for more specs. The -vm option and the path must be on separate lines. The -vm option must come before the -vmargs option. On Linux, the path would typically be /bin/java instead of the Windows path shown above. You must use the Java and Eclipse versions must match (i.e. 32-bit Eclipse runs on 32-bit Java and 64-bit Eclipse runs on 64-bit Java).

Note that option -vm C:\Java\jre6\bin\javaw.exe should be right before -vmargs. Otherwise you'll get 'Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit'

Do this:
1. Go to the folder where eclipse is installed (the one that has the eclipse.exe program in)
2. Open the text file eclipse.ini with notepad or something similar
3. Add the following lines to specify the JVM location using the -vm argument
-vm
c:/jre/bin/javaw.exe
Now start eclipse in the usual way.
Make sure to position the -vm argument before -vmargs, since the latter is passed to the VM on startup it will be too late to set the VM after this.
More info is available on the Eclipse wiki
You could also have changed the system path as per one of the other answers but this would change the JVM being used for the whole system. If you use the eclipse.ini settings it allows everything else to use the latest JVM.

Many hints given already. Anyway I will just provide the recommended way of doing it which might help for future reviews of that question:
Use the eclispe.ini file (folder where the eclipse binary resides)
Add the -vm option with the path of the jre to startup with
i.e Windows
-vm
C:\Java\jdk1.6.0_45\jre\bin\javaw.exe
i.e Linux
-vm
/opt/sun-jdk-1.6.0.02/bin/java
The -vm option must occur after the other Eclipse-specific options (such as -product, --launcher.*, etc), but before the -vmargs option, since everything after -vmargs is passed directly to the JVM.
The -vm option and its value (the path) must be on separate lines.
The value must be the full absolute or relative path to the Java executable, not just to the Java home directory.
see: the eclipse.ini authoring guidelines from eclipse wiki

Since none of the answers worked for me this is my solution:
I downloaded java 6 and i installed it. Then in the program files , inside the folder of java , i copied the folder jre6. I pasted it inside the eclipse folder and renamed it jre.
Thats it! When inside the eclipse installation folder your have a folder named jre , then the java in there is the java that eclipse will run with.
Thank you all for your answers!

These two options worked for me on Windows:
Edit eclipse.ini
-vm
C:/Java/jdk1.7.0_71/jre/bin
-vmargs
...
Copy jre folder to eclipse folder.
So after the copy I have C:\eclipse\jre folder which is a copy of C:\Java\jdk1.7.0_71\jre

If you want to make sure you are running you java apps in Windows 7 with an specific java version:
1 - Check out what which version is running by default. Run cmd to go to the console and type: java -version
C:>java -version
java version "1.6.0_45" Java(TM) SE Runtime Environment (build
1.6.0_45-b06) Java HotSpot(TM) Client VM (build 20.45-b01, mixed mode, sharing)
2 - Change the default jdk by changing the path. Example here. Make sure you java.exe from your desired jdk is before any other java.exe from any other JDK in the path.
ex. in JDK 1.6 you java.exe should be here C:\java\jdk1.6\bin\java.exe.
Once you have changed the path, open a new console and verify again which jdk version you are running.
3 - Make sure in eclipse.ini param -vm another jre version is not set.

I modified eclipse.ini file as follows (added my local JDK path) and it fixed eclipse loading issue.
-vm
C:\Program Files\Java\jdk1.8.0_251\bin

I too faced same issue while running eclipse with different version then default on the system.
I created a symlink of required jre directory under eclipse directory and then it was all working.
For windows user: symlink is similar to creating shortcut
Hope it helps you too.

Eclipse - how to disable update dynamic java source working set [duplicate]

I am trying to get my first taste of Android development using Eclipse. I ran into this problem when trying to run Eclipse, having installed version 4.2 only minutes ago.
After first trying to start Eclipse without any parameters to specify the Java VM, I got an error message saying it couldn't find a Java VM called javaw.exe inside the Eclipse folder, so I found where Java was installed and specified that location as the parameter in the shortcut's target. Now I get a different error, Java was started but returned exit code=13.
Similar questions seem to indicate that it's a 32-bit/64-bit conflict, but I'm 99% positive that I downloaded 64-bit versions of both Eclipse and Java (RE 7u5), which I chose because I have 64-bit Windows 7.
If anyone knows how to confirm that my Eclipse and Java are 64-bit,
that'd be appreciated.
If you think my problem is a different one, please help!
Please speak as plainly as you can, as I am totally new to Eclipse
and Java.

Your version of Eclipse is 64-bit, based on the paths and filenames.
However, the version of Java that it's picking up is 32-bit, as indicated by where it is coming from, on this line:
-vm C:\Program Files (x86)\Java\jre7\bin\javaw.exe
Program Files (x86) is the folder where 64-bit Windows places 32-bit programs.
Program Files is the folder where 64-bit Windows places 64-bit programs.
This can happen when a system has more than one JVM installed, as is often the case on Windows 64-bit (for example, the JRE download page uses the bit-ness of the browser to determine what bit-ness download to offer you, and many people use(d) 32-bit browsers even though they run 64-bit Windows).
The best way to fix this, assuming you do in fact have 64-bit JRE or JDK on your system, is to specify in eclipse.ini exactly which JVM you want it to use. The instructions are detailed in the Eclipse wiki page, but basically you have to specify the -vm option in the ini file - make sure to read the wiki page carefully as the format is very specific.
Specifying the JVM path in eclipse.ini is strongly recommended because doing so isolates Eclipse from any potential changes to your system PATH that some program installers might make (I'm talking to you, Oracle!).
Another option would be to download and use 32-bit Eclipse instead of 64-bit, but it's still strongly recommended to specify the path to the JVM in eclipse.ini.
Left for historical reference:
To check your version of Java, run
java -version
in a console (command prompt). On Windows 7 with 64-bit Java 6 I get:
java version "1.6.0_27"
Java(TM) SE Runtime Environment (build 1.6.0_27-b07)
Java HotSpot(TM) 64-Bit Server VM (build 20.2-b06, mixed mode)
Note the 3rd line, which shows that this is a 64-bit version.
On a 32-bit version you'll get something like:
Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing)
If you are on a 64-bit machine, then you can install the 64-bit JDK and uninstall the 32-bit one. For instance on Windows 10, just go to Settings and under Apps, you will find Java. Click on it and you will find all the different versions. Now you can select which one to uninstall.

I got this error and found that my PATH variable (on Windows) was probably changed. First in my PATH was this entry:
C:\ProgramData\Oracle\Java\javapath
...and Eclipse ran "C:\ProgramData\Oracle\Java\javapath\javaw" - which gave the error. I suspect that this is something that came along with an installation of Java 8.
I have several Java versions installed (6,7 and 8), so I removed that entry from the PATH and tried to restart Eclipse again, which worked fine.
If it's doesn't work for you, you'll need to upgrade your JDK (to the Java versions - 8 in this case).
Instructions on how to edit PATH variable

There are working combinations of OS, JDK and Eclipse bitness. In my case, I was using a 64-bit JDK with a 32-bit Eclipse on a 64-bit OS. After downgrading the JDK to 32-bit, Eclipse started working.
Use one of the following combinations.
32-bit OS, 32-bit JDK, 32-bit Eclipse (32-bit only)
64-bit OS, 32-bit JDK, 32-bit Eclipse
64-bit OS, 64-bit JDK, 64-bit Eclipse (64-bit only)

If you have recently installed Java 8 and uninstalled Java 7, install JDK 8 and retry.

For me the solution was to go into (on Windows 8.1):
System > Advanced system setting > Environment Variables
Under 'System variables' in the 'Path' variable there was the following first:
C:\ProgramData\Oracle\Java\javapath;
I removed this and Eclipse worked again!

I had the same issue, Java was started but returned exit code=13.
My solution was to create an environment variable to Windows properties variable name = PATH variable value = C:\Program Files\Java\jdk1.7.0_02\bin, not to C:\Program Files (x86)\Java\jre7\bin.
Next I added a line to file eclipse.ini → C:\Program Files\Java\jdk1.7.0_02\bin\javaw.exe.
That worked for me.

The issue was fixed by doing the following steps.
Eclipse finds the JAVA executables from
'C:\ProgramData\Oracle\Java\javapath'
The folder structure will contain shortcuts to the below executables,
i. java.exe
ii. javaw.exe
iii. javaws.exe
For me the executable paths were pointing to my Program Files(x86) (home for 32 bit applications) folder location
I corrected it to Program Files (which homes 64-bit applications) and the issue got resolved
Please find the screenshot for the same.

Adding vm argument to .ini file worked for me
-vm
C:\Program Files\Java\jdk1.7.0_65\bin\javaw.exe
Adding more details to this
for sts 3.9.18 release I was getting error Java was started but returned exit code=13 and for latest release same
issue just the returned exit code was 14. This was due to default java chosed was of 32 bit and this version of sts/eclipes is for 64 bits. resolved this by setting 64 bits version of java in STS.ini file as
-vm
C:\Progra~1\Java\jdk1.8.0_131\bin\javaw.exe
This is before vmargs parameters in the file.

The strangest fix ever. Look at your Eclipse path, and make sure you do not have strange characters (like !, #, and #). It worked for me.

Locate eclipse.ini:
Often at C:\Users\xxx\eclipse\jee-neon\eclipse, add
-vm
C:\Program Files (x86)\Java\jre7\bin\javaw.exe
after
--launcher.appendVmargs

I uninstalled Java update 25, and the issue was solved.

A clean reinstall of the Java JDK did the trick in my case. I am running Eclipse 4.4 (Luna) like a charm now.

You have to go to the folder where eclipse is installed and then you have to change the eclipse.ini file.
You have to add
-vm
C:\Program Files\Java\jdk1.8.0_202\bin\javaw.exe
Your eclipse.ini file will look like the below screenshot

Confirm your installation by checking you now have this folder
C:\Program Files\Java\jre1.8.0_45\

The solution is simple: Put the "eclipse" folder on "C:/Program Files". If it does not work, put it in "C:/Program Files (x86)".

I had this message when I had forgot to install the JDK.

The best answer here is too long. I cannot comment so I added my answer.
Go here:
http://www.oracle.com/technetwork/java/javase/downloads/index.html
Download the latest SDK (of course for x64 if your computer is x64)
Install it
Now the party is finished, and it's time to work with Eclipse ;)

I had the same problem. I was using Windows 8 with a 64-bit OS. I just changed the path to Program Files (x86) and then it started work. I put this line in the eclipse.ini file:
-vm
C:\Program Files (x86)\Java\jre7\bin\javaw.exe

Make sure you don't have special characters (%, $, #, etc.) at Eclipse path.

If you install a 64-bit Eclipse version on a PC with a 32-bit JRE this is guaranteed to occur.
So the solution is quite straightforward: You need to synchronise them by updating either one. This shall happen when downloading Oracle Fusion middleware and Eclipse expects a 32-bit environment while your JRE is 64-bit and your JAVA home is pointing to a 64-bit JDK.

Under system environment variables, make sure "C:\ProgramData\Oracle\Java\javapath" is removed.
Under system environment variables, make sure "C:\Program Files\Java\jdk1.8.0_131\bin" is added.

I had this issue. I installed Java 8 update 25 via Chrome, and therafter attempting to start Eclipse gave the mentioned error.
Uninstalled that update, and Eclipse works again.

I tried some of the solutions, but not worked for me.
Finally, I found another way, ...
Go to Environment Variables → System Variables
Set C:\Program Files\Java\jdk1.7.0_02\bin\javaw.exe to the path in the system variables.
Try it. It worked for me...

I tried the following solution:
I created a shortcut of javaw.exe from path C:\Program Files\Java\jdk1.7.0_71\bin and pasted it into the path C:\ProgramData\Oracle\Java\javapath.
After that, I launched Eclipse, and it worked for me.

I also encountered the same issue. It turned out that the environment variable Path was pointing to an incorrect Java version.
Please check the environment variable and point it to the correct Java. For example:
C:\Program Files (x86)\Java\jdk1.6.0_17\bin
To check the environment variable, go to:
Computer → properties → Advanced system settings → Advanced -> Environment variables

I have just solved the same issue upon setting up my Windows 8.1 PC. Exactly like #George Papatheodorou mentioned above (sorry I cannot add a comment), Eclipse and JRE must be both 64 bit or 32 bit.
However, it seems for Windows 8/8.1 environment, you are going to get 32-bit JRE by default (and I do not know where to change that default for the download), as explained here: http://java.com/en/download/faq/win8_faq.xml
I was using 64-bit Eclipse so there was a discrepancy. I then installed 32-bit Eclipse and everything works fine this time.
So before bothering changing any environment variables, check your JRE and Eclipse version.
Of course you can use 64-bit JRE with 64-bit Eclipse. Just make sure they match because Windows 8.1 will give you 32-bit by default.

I had a similar error after installing Java 8 on my Windows 7 system, 64 bit system.
Changing environment variables, etc. did not help. So I tried to remove the Java Update 8, but that too did not help. Downloading and installing the 64-bit version of Java 8 SDK fixed my problem. I hope this helps.

I had the same issue after I upgraded my JDK from 1.7 to 1.8. I'm using Eclipse 4.4 (Luna). The error is gone after I degrade JDK to 1.7.

Please check whether you have set two JAVA paths in the Environment Variable section. If you already installed two versions of the JDK, it might be, then double check you have put PATH for Java like below.
PATH --> C:\ProgramData\Oracle\Java\javapath
and also
JAVA_HOME ---> C:\Program Files\Java\jdk1.7.0_02\bin
If both are there, then this sort of error may occur.
If it's OK, then check in the ".ini" file the below area is OK or not.
Open ".ini" file and check
-VM path is C:\Program Files\Java\jdk1.7.0_79\bin\
If not, please set it like that and run again.

It could be due to too little memory. You can modify the eclipse.ini file to increase the memory. Something like this might help you: FAQ How do I increase the heap size available to Eclipse?

STS launch error - Java was started but returned exit code=13

So I installed STS a while back now onto my Windows 7 64-bit machine, every time I try run STS I get the attached Java exit code=13 error below.
I don't have have Eclipse installed into my machine, I mention this because every time I have tried to Google this error code threads about the same issue happening on Eclipse come up.
I have also tried checking if Java is installed on my machine which it is.
Does anyone know how to resolve this?

First you need to check that you are using 64 bit java.
Next you need to point to that version of java in your STS.ini file.
You can do this by specifying the -vm option in the STS.ini file. The -vm option must be placed after the other Eclipse-specific options (such as -product, --launcher.*, etc), but before the -vmargs option.
-vm argument might look like:
-vm
C:\jdk1.7.0_21\bin\javaw.exe
or
-vm C:\jdk1.7.0_21\bin\javaw.exe
or
-vm C:\jdk1.7.0_21\jre\bin\java.exe
If you encounter Java was started but returned exit code=1 point the `-vm option to jvm.dll
-vm
C:\Development\Java\64bit\jdk1.7.0_09\jre\bin\server\jvm.dll
Here is how I added it in my STS.ini file.
-startup
plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
--launcher.library

Stack overflow answer by DNA to similar question

I faced this issue due to my java update.
So below is the cause
Or java 64 bit and eclipse 32 bit version
You have java version 32 bit and eclipse 64 bit version
External cause, if you have two version of java installed(32 bit and 64 bit), if one got updated means your path variable pointing to
java will change.
Solution:-
Check your java version is 32 bit or 64 bit with command below
java -d64 -version
If It's 64 bit it will show
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
If It's not
It will show something like this
Error: This Java instance does not support a 64-bit JVM.
Please install the desired version.
Based on the java version change your STS, to either 32 bit or 64 bit.

Check that you are using correct java version for your OS architecture, 32 or 64 bits

STS mostly ends up with error code 13 if you are using for the first time. Here is a fix to the problem. Please visit this link I found here https://youtu.be/cMClVM6rzuc.
here is the summary of the solution
- The Error while launching STS is mostly because you have downloaded 32 bit STS bundle from spring.io website. you need to check your system architecture and download the appropriate version. You can watch the video for detailed information. I am 100% sure you will find your solution

If you dowloaded 64 bits version of STS Spring,
check the version of java you have by taping in cmd :
java -d64 -version
If you dont have the jre 64 bits, install it and it will work .

I removed C:\ProgramData\Oracle\Java\javapath from the PATH environment variable. It worked for me then. So basically it's a path variable issue.

please make sure you download the 64bit version from https://spring.io/tools/sts/all.

On the STS page, the Download STS button downloads the version for 32-bit Windows by default. Under the download button, click See all versions (https://spring.io/tools/sts/all). From there you can click the menu button and select the 64-bit Windows version.

Just install 32-bit JRE (if you have 64 bit already installed) and point -vm to this 32-bit JRE as mentioned above.

So basically when you go to Spring website, it doesnt understand your client OS and prompts you to download 32 bit version. I faced the same issue and explicitly had to download 64 bit version, by clicking on "see all versions". Also some suggested removing "C:\ProgramData\Oracle\Java\javapath" entry from Path, but while it is true if you have actually downloaded JDK 1.8, it is not going to help resolve the specific issue here.

Open "SpringToolSuite4.ini" or sts.ini and make sure you have javaw.exe path in .ini file.
-vm
D:\Projects\Softwares\JDK\bin\javaw.exe
File should look similar as below.
-startup
plugins/org.eclipse.equinox.launcher_1.5.400.v20190515-0925.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.1000.v20190125-2016
-product
org.springframework.boot.ide.branding.sts4
--launcher.defaultAction
openFile
-vm
D:\Projects\Softwares\JDK\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.8
-Xms256m
-Xmx1024m
-XX:+UseG1GC
-XX:+UseStringDeduplication
--add-modules=ALL-SYSTEM

You likely installed the default version of STS from the spring.io website which is normally the 32 bit version.
Click to see all versions and download the windows 64 bit version from the next page.
Good luck.

By Removing following java path from environment variables path is fixed the issue.
C:\Program Files (x86)\Common Files\Oracle\Java\javapath
Have another jdk in path.

Initial I uninstall another Java SE Development Kit , next I added the follow path in the *SpringToolSuite4.ini in my case:
*(depends of your IDE that you´ve installed)
-vm
C:\Program Files\Java\jdk1.8.0_131\bin\java.exe**

You just need to reinstall JDK(same or latest version) and STS(not always required).

First of all, please check your STS path. Remove if there is any special character such as # or etc in your path. After verify this, please go for any of the above solutions ;)

The first step is like the is already related above: open the document parameters of configuration "STS" and send the commands below to "openFile":
-vm
C:\Program Files\Java\jdk-11.0.2\bin\javaw.exe
To check the version of JDK, on your prompt do the command:
java -version
You will find in "build".
If you still having the problem with JDK path not finded, the path to found your JDK on pc is:
my computer -> archives and programs -> java -> jdk -> bin -> javaw
when you reach at this, click and inspect the properties of and copy the route to put on command after -vm.

Eclipse Kepler, Java was Started but returned Exit code=13 [duplicate]

I am trying to get my first taste of Android development using Eclipse. I ran into this problem when trying to run Eclipse, having installed version 4.2 only minutes ago.
After first trying to start Eclipse without any parameters to specify the Java VM, I got an error message saying it couldn't find a Java VM called javaw.exe inside the Eclipse folder, so I found where Java was installed and specified that location as the parameter in the shortcut's target. Now I get a different error, Java was started but returned exit code=13.
Similar questions seem to indicate that it's a 32-bit/64-bit conflict, but I'm 99% positive that I downloaded 64-bit versions of both Eclipse and Java (RE 7u5), which I chose because I have 64-bit Windows 7.
If anyone knows how to confirm that my Eclipse and Java are 64-bit,
that'd be appreciated.
If you think my problem is a different one, please help!
Please speak as plainly as you can, as I am totally new to Eclipse
and Java.

I got this error and found that my PATH variable (on Windows) was probably changed. First in my PATH was this entry:
C:\ProgramData\Oracle\Java\javapath
...and Eclipse ran "C:\ProgramData\Oracle\Java\javapath\javaw" - which gave the error. I suspect that this is something that came along with an installation of Java 8.
I have several Java versions installed (6,7 and 8), so I removed that entry from the PATH and tried to restart Eclipse again, which worked fine.
If it's doesn't work for you, you'll need to upgrade your JDK (to the Java versions - 8 in this case).
Instructions on how to edit PATH variable

There are working combinations of OS, JDK and Eclipse bitness. In my case, I was using a 64-bit JDK with a 32-bit Eclipse on a 64-bit OS. After downgrading the JDK to 32-bit, Eclipse started working.
Use one of the following combinations.
32-bit OS, 32-bit JDK, 32-bit Eclipse (32-bit only)
64-bit OS, 32-bit JDK, 32-bit Eclipse
64-bit OS, 64-bit JDK, 64-bit Eclipse (64-bit only)

If you have recently installed Java 8 and uninstalled Java 7, install JDK 8 and retry.

For me the solution was to go into (on Windows 8.1):
System > Advanced system setting > Environment Variables
Under 'System variables' in the 'Path' variable there was the following first:
C:\ProgramData\Oracle\Java\javapath;
I removed this and Eclipse worked again!

I had the same issue, Java was started but returned exit code=13.
My solution was to create an environment variable to Windows properties variable name = PATH variable value = C:\Program Files\Java\jdk1.7.0_02\bin, not to C:\Program Files (x86)\Java\jre7\bin.
Next I added a line to file eclipse.ini → C:\Program Files\Java\jdk1.7.0_02\bin\javaw.exe.
That worked for me.

The issue was fixed by doing the following steps.
Eclipse finds the JAVA executables from
'C:\ProgramData\Oracle\Java\javapath'
The folder structure will contain shortcuts to the below executables,
i. java.exe
ii. javaw.exe
iii. javaws.exe
For me the executable paths were pointing to my Program Files(x86) (home for 32 bit applications) folder location
I corrected it to Program Files (which homes 64-bit applications) and the issue got resolved
Please find the screenshot for the same.

Adding vm argument to .ini file worked for me
-vm
C:\Program Files\Java\jdk1.7.0_65\bin\javaw.exe
Adding more details to this
for sts 3.9.18 release I was getting error Java was started but returned exit code=13 and for latest release same
issue just the returned exit code was 14. This was due to default java chosed was of 32 bit and this version of sts/eclipes is for 64 bits. resolved this by setting 64 bits version of java in STS.ini file as
-vm
C:\Progra~1\Java\jdk1.8.0_131\bin\javaw.exe
This is before vmargs parameters in the file.

The strangest fix ever. Look at your Eclipse path, and make sure you do not have strange characters (like !, #, and #). It worked for me.

Locate eclipse.ini:
Often at C:\Users\xxx\eclipse\jee-neon\eclipse, add
-vm
C:\Program Files (x86)\Java\jre7\bin\javaw.exe
after
--launcher.appendVmargs

I uninstalled Java update 25, and the issue was solved.

A clean reinstall of the Java JDK did the trick in my case. I am running Eclipse 4.4 (Luna) like a charm now.

You have to go to the folder where eclipse is installed and then you have to change the eclipse.ini file.
You have to add
-vm
C:\Program Files\Java\jdk1.8.0_202\bin\javaw.exe
Your eclipse.ini file will look like the below screenshot

Next I added a line to file eclipse.ini → C:\Program Files\Java\jdk1.7.0_02\bin\javaw.exe.
That worked for me.

The issue was fixed by doing the following steps.
Eclipse finds the JAVA executables from
'C:\ProgramData\Oracle\Java\javapath'
The folder structure will contain shortcuts to the below executables,
i. java.exe
ii. javaw.exe
iii. javaws.exe
For me the executable paths were pointing to my Program Files(x86) (home for 32 bit applications) folder location
I corrected it to Program Files (which homes 64-bit applications) and the issue got resolved
Please find the screenshot for the same.

Adding vm argument to .ini file worked for me
-vm
C:\Program Files\Java\jdk1.7.0_65\bin\javaw.exe
Adding more details to this
for sts 3.9.18 release I was getting error Java was started but returned exit code=13 and for latest release same
issue just the returned exit code was 14. This was due to default java chosed was of 32 bit and this version of sts/eclipes is for 64 bits. resolved this by setting 64 bits version of java in STS.ini file as
-vm
C:\Progra~1\Java\jdk1.8.0_131\bin\javaw.exe
This is before vmargs parameters in the file.

The strangest fix ever. Look at your Eclipse path, and make sure you do not have strange characters (like !, #, and #). It worked for me.

Locate eclipse.ini:
Often at C:\Users\xxx\eclipse\jee-neon\eclipse, add
-vm
C:\Program Files (x86)\Java\jre7\bin\javaw.exe
after
--launcher.appendVmargs

I uninstalled Java update 25, and the issue was solved.

A clean reinstall of the Java JDK did the trick in my case. I am running Eclipse 4.4 (Luna) like a charm now.

You have to go to the folder where eclipse is installed and then you have to change the eclipse.ini file.
You have to add
-vm
C:\Program Files\Java\jdk1.8.0_202\bin\javaw.exe
Your eclipse.ini file will look like the below screenshot

It turned out I only had the 32-bit Java runtime installed.
C:\Program Files (x86)\Java\jre1.8.0_45\
All Eclipse really wanted was for me to install the 64-bit Java runtime. <= SOLVED
Java SE Runtime Environment 8u45 jdk-8u45-windows-x64.exe
http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html
Confirm your installation by checking you now have this folder
C:\Program Files\Java\jre1.8.0_45\

The solution is simple: Put the "eclipse" folder on "C:/Program Files". If it does not work, put it in "C:/Program Files (x86)".

I had this message when I had forgot to install the JDK.

The best answer here is too long. I cannot comment so I added my answer.
Go here:
http://www.oracle.com/technetwork/java/javase/downloads/index.html
Download the latest SDK (of course for x64 if your computer is x64)
Install it
Now the party is finished, and it's time to work with Eclipse ;)

I had the same problem. I was using Windows 8 with a 64-bit OS. I just changed the path to Program Files (x86) and then it started work. I put this line in the eclipse.ini file:
-vm
C:\Program Files (x86)\Java\jre7\bin\javaw.exe

Make sure you don't have special characters (%, $, #, etc.) at Eclipse path.

If you install a 64-bit Eclipse version on a PC with a 32-bit JRE this is guaranteed to occur.
So the solution is quite straightforward: You need to synchronise them by updating either one. This shall happen when downloading Oracle Fusion middleware and Eclipse expects a 32-bit environment while your JRE is 64-bit and your JAVA home is pointing to a 64-bit JDK.

Under system environment variables, make sure "C:\ProgramData\Oracle\Java\javapath" is removed.
Under system environment variables, make sure "C:\Program Files\Java\jdk1.8.0_131\bin" is added.

I had this issue. I installed Java 8 update 25 via Chrome, and therafter attempting to start Eclipse gave the mentioned error.
Uninstalled that update, and Eclipse works again.

I tried some of the solutions, but not worked for me.
Finally, I found another way, ...
Go to Environment Variables → System Variables
Set C:\Program Files\Java\jdk1.7.0_02\bin\javaw.exe to the path in the system variables.
Try it. It worked for me...

I tried the following solution:
I created a shortcut of javaw.exe from path C:\Program Files\Java\jdk1.7.0_71\bin and pasted it into the path C:\ProgramData\Oracle\Java\javapath.
After that, I launched Eclipse, and it worked for me.

I also encountered the same issue. It turned out that the environment variable Path was pointing to an incorrect Java version.
Please check the environment variable and point it to the correct Java. For example:
C:\Program Files (x86)\Java\jdk1.6.0_17\bin
To check the environment variable, go to:
Computer → properties → Advanced system settings → Advanced -> Environment variables

I have just solved the same issue upon setting up my Windows 8.1 PC. Exactly like #George Papatheodorou mentioned above (sorry I cannot add a comment), Eclipse and JRE must be both 64 bit or 32 bit.
However, it seems for Windows 8/8.1 environment, you are going to get 32-bit JRE by default (and I do not know where to change that default for the download), as explained here: http://java.com/en/download/faq/win8_faq.xml
I was using 64-bit Eclipse so there was a discrepancy. I then installed 32-bit Eclipse and everything works fine this time.
So before bothering changing any environment variables, check your JRE and Eclipse version.
Of course you can use 64-bit JRE with 64-bit Eclipse. Just make sure they match because Windows 8.1 will give you 32-bit by default.

I had a similar error after installing Java 8 on my Windows 7 system, 64 bit system.
Changing environment variables, etc. did not help. So I tried to remove the Java Update 8, but that too did not help. Downloading and installing the 64-bit version of Java 8 SDK fixed my problem. I hope this helps.

I had the same issue after I upgraded my JDK from 1.7 to 1.8. I'm using Eclipse 4.4 (Luna). The error is gone after I degrade JDK to 1.7.

Please check whether you have set two JAVA paths in the Environment Variable section. If you already installed two versions of the JDK, it might be, then double check you have put PATH for Java like below.
PATH --> C:\ProgramData\Oracle\Java\javapath
and also
JAVA_HOME ---> C:\Program Files\Java\jdk1.7.0_02\bin
If both are there, then this sort of error may occur.
If it's OK, then check in the ".ini" file the below area is OK or not.
Open ".ini" file and check
-VM path is C:\Program Files\Java\jdk1.7.0_79\bin\
If not, please set it like that and run again.

It could be due to too little memory. You can modify the eclipse.ini file to increase the memory. Something like this might help you: FAQ How do I increase the heap size available to Eclipse?
