Has anyone had any success using JDK 16 (https://jdk.java.net/16/) early access build with IntelliJ?
I am able to use JDK 15 early access builds, but when I try JDK 16 I get an error message:
Error: Cannot determine path to 'tools.jar' library for 16 (path/to/jdk-16)
All of the research I've done says JDK stores tools.jar inside of the path/to/jdk-16/lib folder. Thing is, tools.jar isn't there in the JDK 15 package either, yet JDK 15 works fine.
If anyone has any clue on how to fix this issue I'd appreciate it. I'm still trying, and if I figure it out I'll update this post.
Thanks in advance.
There was an issue: IDEA-243962. It is fixed now in 2020.2 version. EAP version is already available here.

I am working with Maven for the first time. But I couldn't progress because of the error. I tried many things like Invalidate Caches, JDK version, Maven version etc. How can I fix it?

Intellij 2020.02
JDK 14
Your IntelliJ IDEA version has no support for JDK 18 as this IDE version was released long before JDK 18 which has introduced some changes to the layout and required updated support from the IDE side. Please update to the current IDE release.
This issue is driving me crazy, guys. Take a look.
I have downloaded and unzipped maven 3.6.3 on my Program Files folder, I set the environment variables properly, I think, but when I try to run:
As you can see in the following pictures, my JAVA_HOME is set right as it should be, pointing to a JDK 11:
I had no problem using that JDK until now for eclipse and maven inside eclipse. I've reinstalled Java already, reboot several times, but nothing seems to fix
My system had some misconfiguration and I cant understand why. But to solve the problem I deleted the jdk folder, removed java from official uninstaller, donwloaded and installed OpenJDK 11 from this link and the problem was solved, maven now works:
Thank you guys for your help!
I had some problems with JRE versions, so I tried to change it using the plugin Choose Runtime. I changed it to Java 1.8.0_112-release-287-b2. Now, when trying to start IntelliJ, i get an unsupported Java version error: Cannot start under Java 1.8.0_112-release-287-b2: Java 11 or later is required. I have tried to modify the runtime path in the ide64.exe.jdk file, but it seems like the old jdk IntelliJ ran on has been deleted. I also tried reinstalling intellij, no luck either. Anyone know how to get back the JDK? do I just download it from oracle and install it in the IdeaIC2020.3\jdks\ folder?
Thanks,
Jakob
I went to the jdks folder and deleted all contents. This fixed the issue. IntelliJ started without a problem.
This question already has an answer here:
Setting up JDK 10 in IntelliJ IDEA: the selected directory is not a valid home for JDK
(1 answer)
Closed 4 years ago.
Please refer to the picture below.
I changed the default java installation path to D:\Program Files\Java\
I created a new java project.
Firstly, it reminds me the java path is not existed and the program cannot run.
When I tried to modify the path to my location, it rejected me saying it's an invalid path.
Why?
Please note: this post didn't resolve my question:
I know the difference of jdk and jre; I do reinstalled latest java repeatedly.
Only, I didn't want to install java to C disk. I have set my JDK_HOME and JRE_HOME to my location.
You're right! IntelliJ version 2018 resolve this issue.
2017.1 is not compatible with java 10. For official java 10 support please use 2018.1. Also It is possible to use jdk10 with 2017.3 build,
but there would be no syntax highlighting.
Source, emphasis mine
Java 10 support starts from build 2018.1.
take a look at this IDEA 2017.1.1 doesn't detect JDK 10
You have to upgrade your IDE now.
You are getting that error because your IDE is out of date. Updating your IDE here should do the trick.
I am running Mac OS X 10.5 and I using eclipse to code my java projects. Eclipse has been running fine until today when I suddenly get the error when I try to run my Main.java:
An internal error occurred during: "Launching Main".
java.lang.NoClassDefFoundError
I installed Java for Mac OS X 10.5 Update 4 from this page earlier today so I was wondering if that might caused a problem. I have tired reinstalling eclipse (latest version) and find people with similar problems online but have not managed to resolve it. I was wondering if anyone have any idea for a fix?
Update:
I first tried to clean up the project through eclipse but this did not work. I then entered the workspace file and removed the already compiled classes, figured it might have to do something with that but that didnt help either. I started a new workspace with a new project and i get the same error.
I then tried to add my owm JRE file manually. What i interesting though is that there is no 1.6.0/Home in the versions folder. But since 1.5.0 did not seem to be added in eclipse I added this from the Versions/1.5.0/Home but I still get the same error. This is starting to become really annoying since I use eclipse atleast 4 hours a day in school.
Maybe my whole java got messed up after the installation of the new Java SE 6? If so how do i revert to only 1.5.0_
Thank you for your replies!
I suspect your JRE install location has changed due to the update. Go to Window > Preferences > Installed JREs and add a new default JRE that points to your updated Java. Then eclipse will rebuild all projects and hopefully, things should be fine again.
Clean your project. This error means that there is a missing .class that was there during compilation.
