What are all netbeans project directories, where it can store various metadata?
I'd like to move my project to other computer (with new Netbeans version)
There are some directories where Netbeans stores data for the project (not just src directory), like .netbeans..cashe
It sometimes stores additional libraries and other data somewhere else.
So, where to look for all that project data?
It is only one part of the question. The other part is : does Windows 10 home
have some problems with developing application on it? Because when I installed Netbeans 8.2 on it and tried to open (moved - maybe incorrectly) project , it made very strange things, when tried create new project, it made
nothing at all. I am totally new to Windows 10 home (had Windows XP)
Thank you and sorry for my English, if it sounds foreign
You should not approach this way at all.
In old machine,
export your project as a zip file. refer here
In new machine
Install NetBeans
Create a workspace
Then import the project to your new work space

Since a few days, navigating the file system with Netbeans is VERY slow (more than two minutes to access a file, and if you have to navigate a file system, it is true every time. I have exactly the same problem after clearing the cache, and with Netbeans 8.2 and Netbeans 12 (Netbeans 8 with Java 8, and Netbeans 12 with Java 17 in my tests).
Strangely I don't have the same problem with regular Java file choosers which I use in my projects. For example, if I click on "Open Project", the IDE is frozen for sometimes 2 or 3 minutes before I can see the file navigator.
When I am looking in the task manager while trying to open a project for example, it appear that Network usage is very low (1% to 0%), CPU also very low (less than 2%)
I am talking about Netbeans itself, for example if I want to open an existing project, or adding a jar file to the list of Jar libraries for an existing project
The standard Swing JFileChooser works correctly. With this example code the navigation is immediate (as expected):
JFileChooser chooser = new JFileChooser();
chooser.setDialogType(JFileChooser.OPEN_DIALOG);
chooser.setDialogTitle("Test FileChooser");
chooser.setFileSelectionMode(JFileChooser.FILES_ONLY);
int ret = chooser.showOpenDialog(null);
if (ret == JFileChooser.APPROVE_OPTION{
System.out.println(chooser.getSelectedFile().getAbsolutePath());
}
I am on Windows, on my workplace network (I am working on local files on my PC, but there are two remote drives which are accessible on the network). I only have problems with Netbeans, other apps have no problem with the file system.
My problem is with Netbeans itself navigating the file system (for example opening an existing project, or adding a jar file as a library for a project)
This looks to behave exactly as this bug: https://bz.apache.org/netbeans/show_bug.cgi?id=42079, except that it does not happen with the Swing JFileChooser as shown above.
Is it a known problem, and if it is, is there a mean to fix it? I was thinking for example about a setting on the command line used to start Netbeans.
There is a bug in netbeans with links from the desktop, that behaves like you described. Try to remove all links from the desktop and default location for the open file dialog.
issues.apache.org/jira/browse/NETBEANS-1537
It was a BROKEN PATH in a link on the desktop in Windows 10, in my case.
NetBeans 12.5 -> Creating a new project dialog, than "Browse" to choose appropriate directory took a very long time. I tried to test links on my desktop. I found one old "broken link". Broken in terms - it pointed out to non existent path. I corrected this path in this link and... voilà, magically NetBeans is working correctly.
Ok -- this is crazy -- but after trying everything listed, here is what finally worked for me.
I created a Batch file on the desktop to point to the netbeans64.exe app. the secret for me was to NOT do a cd to the netbeans location.. but to call the app in using the full path. Here is what my batch file looks like
"C:\Program Files\NetBeans-15\netbeans\bin\netbeans64.exe"
I know it seems way too easy.. but it works for me. As Sam Snead said about the latest golf gear back in the 60's "I ain't no scientist. just a believer.." LOL!!!
I had the same problem. As they wrote here, it is necessary to check the links on the desktop. Removing bad links helped me.
I had the same issue on Windows, thanks to you guys I solved it by removing the symbolic links (shortcuts) from the desktop, but not from any desktop, I mean that this method didn't work for me when I removed them from the user desktop "C:\Users\user\Desktop", it only worked when I removed them from the public desktop, which is located at "C:\Users\Public\Desktop".
I hope this clarification helps and sorry I don't have enough reputation here on StackOverflow to comment, so I had to post this as an answer....
I find that this happens when I run Netbeans without administrator rights.
With admin rights it works fine.
Had this issue with Netbeans 15. Resolved it by removing a broken shortcut from my desktop.
I'm going to college for programming at a tech school right now. I deleted a project in windows explorer on windows 7 ultimate 64. I can't seem to delete the project inside Eclipse to reuse the folder in the same work space to do my programming homework projects. Yes I need to use the same folders and work spaces for class. I've already tried deleting the Eclipse folder, the meta data folder, and all of the Eclipse folders. Doing all of this has netted me the result of Eclipse telling me I can't use the same folder because a project is already in it even though the folder has been deleted and remade. I can't seam to find any possible reason how eclipse is remembering that there was a project there.
Any help would be greatly appreciated on this task.
OK, I have a really basic (read stupid) question. I am just beginning Java programming, and am using Eclipse 3.7.2. I have done a few beginning projects without any problems. All of a sudden, when I create a new project using the wizard, it is not creating the src/.java file. When I try to manually add it after creating the project, I end up getting some cryptic error messages.
I have re-followed several walk-throughs on project creation for clues as to any option I may have accidentally un-checked and no luck.
Googling the answer brings up results for more advanced problems that are unrelated.
I have combed the preferences, but nothing looks obvious, and
I have gone hunting for any user app data I could delete to force a clean slate.
I have even created a new instance of Eclipse to a different directory and still have the same result.
My son's instance, which is on the same computer still creates the .java file from the wizard. The only difference is that my instances have the Android SDK installed (I am trying to create basic Java projects and not Android projects).
I am at a loss, and have lost a lot of time trying to correct the situation. What do I need to do to reenable the creation of a src/.java file in Eclipse?
Screenshots (click on image for full size):
Make sure you are choosing a java project from the right folder in the wizard. It sounds like it is creating an android java project, which is probably why your src folder is missing. See if there is a helloworld project under example projects too in the wizard, that may get you started too. Screenshot may help us. I want to see which project type you choose and which folder it is in.
How about changing eclipse to point to a new workspace. That may drop the android settings. Under the file menu, choose switch workspace and pick a new location. Thats most likely why a new install did not fix it. That workspace may have android settings in it, so change to a new folder somewhere else to test it like c:\workspace2\
Here's a good tutorial I found that may help too.
eclipse java project tutorial
I have been working as a programmer for approx 15 years. I have significant experience with 3 languages. Object Pascal, C# and Python. I just took a job (like two days ago) as a project manager for a Java project that has been written with the following tech stack.
Java EE
Eclipse Helios
Tomcat
Spring
MySQL
Code is in SVN
In preperation of starting the job, I read a couple of books on Java and played around with eclipse. The language doesn't bother me at all - it's very similar to C#. What I'm really struggling with now feels more like how to get started.
I've sync'd the code from the SVN repository, but literally am not sure how to proceed. I think I'm use to having solution or a project file to "open" (like in Delphi and Visual Studio). So, do I need to create a new workspace and "import" it from the file system?
I apologies for the newbie questions. I just feel a bit lost getting started here. Maybe someone that has recently come from a Visual Studio background can sympathize with me situation! :)
Thanks in advance for your help.
Well, it depends a bit on how your company's SVN is organized. For example, do they check in the Eclipse project settings, or do they expect you to check out the code and then generate Eclipse settings? Both are common approaches.
Assuming they have project settings in SVN, you should be able to just import them. You can either directly import from SVN as a new project (using the Eclipse new project wizard), or you can check out the code from SVN with an external tool (e.g. Tortoise) and then use Eclipse's import wizard to import the project. Go to Import -> General -> Existing projects into workspace, then browse to the location of your SVN working copy, and it should automatically pick up the Eclipse project(s) there.
update following up on your comments, let me expand a bit. Say, you check out a working copy from SVN using Tortoise, for example to c:\foo. You can then import any projects in that working copy into Eclipe, using the "Import existing projects into workspace" option I mentioned above. In the import wizard, you can choose if Eclipse should copy the actual code into its workspace directory, or should leave it where it is and just keep references. This is personal taste but I usually do not let Eclipse copy the code into its own workspace. That way, I can work with the code in Eclipse (and do SVN updates/commits directly from Eclipse), but also can quite easily do operations on my svn working copy outside Eclipse.
A workspace in Eclipse can contain multiple Projects.
When you open eclipse it has you select which workspace to use, and then you should be able to import the code into eclipse as a new Project. Have you tried using the Project Wizard?
You won't find an exact equivalent of the .csproj file, the closest you get is the .project & .classpath files, between them eclipse has all the information to describe a project. If your svn checkout contains the .project file, you can directly import your project into eclipse using the Import Wizard. Else you can try creating a new project and pointing it to your svn checkout.
I am very new to Eclipse (Galileo, Eclipse IDE for Java Developers) and working on my first Android app, but have used SVN on many other kinds of projects and development. Last night I took my first crack at pushing the new source into a shared repository (at work) and then pulling it back down at home.
Based on an SO question/answer, I had ignored the bin and gen folders, but added everything else. When I got home, I had hoped it would be as easy as pointing eclipse to the newly downloaded source tree.
I tried setting the workspace (requested when eclipse started) to the precise folder holding all source. Nothing showed up. It was as if I were starting fresh regardless of all the source and files sitting in the workspace folder.
Then I thought maybe I needed to open a "project" file to get things rolling. Opening the .project file yielded the contents of that file in the XML editor of eclipse.
What am I missing here? Is the project metadata not stored in the source tree? Do I have to build project metadata up on every machine that gets a working copy of the source? Is this something wrong with my home Eclipse install? Can someone give me an overview of how they (successfully) do this?
You should be able to do it like you tried. Make sure you have the Android Development Tools (android eclipse plugin) installed along with the android SDK and make sure you set up ADT before you open the project.
Not checking in the bin directory makes sense to me, but I do check in the gen folder and don't have any problems.
Here is what I do to open a project from SVN if the source is already on the machine:
Open eclipse
Click on File->Import
Select General->Existing Projects into Workspace
Or you can also do this:
Open Eclipse
File -> Import
Select SVN -> Checkout Projects from SVN
Follow the steps to get from SVN
