Eclipse hangs on loading workbench

Question

My eclipse stops loading workbench. I tried already starting with ./eclipse --clean

When starting from console it throws following exception:

java.lang.NullPointerException

Whats wrong with my workbench?

Answer 1

Here's a less destructive method that worked for me:

I'm on Windows machine with a copy of Spring Tool Suite (an extension of Eclipse) which I'm running from a random directory. In my command line prompt, I had to navigate to the directory which contained my STS.exe and run: STS.exe -refresh.

After that, I could open my Eclipse the normal way (which was through a pinned taskbar icon).

Answer 2

Pretty old question but the most simple answer isn't yet posted.
Here it is :
1) In [workspace]\.metadata\.plugins\org.eclipse.e4.workbench delete workbench.xmi file.
In most cases it's enough - try to load Eclipse.
Still you have to re-configure your specific perspective settings (if any)

2) Now getting problems with building projects that worked perfectly? As of my experience following steps help:
- uncheck Projects->Build automatically
- switch to Java perspective (if not yet): Window -> Open perspective -> Java
- locate Problems view or open it: Window -> Show view -> Problems
- right-click on problem groups and select Delete. Be sure to delete Lint errors
- clean the workspace: Project -> Clean... with option Clean all projects
- check Projects->Build automatically
- if problems persist for some projects: right-click project, select Properties -> Android and make sure appropriate Project Build Target is chosen

3) It was always sufficient for me. But if you still get problems - try @george post recommendations

I had this problem in Windows 7, this is what fixed it for me.

cd ~/Documents/workspace/.metalog/.plugins

rm -rf org.eclipse.core.resources

Answer 4

It might also help to try to load and save the workspace with a newer eclipse version:

I am using eclipse 3.8. When starting up the splash screen would hang. There were no error messages in the log. What helped was to open the workspace with eclipse 4.2.2. After opening and closing the workspace I was able to load it again with 3.8.

Answer 5

Get a backup copy of the .metadata/.plugin/org.eclipse.core.resources folder, then delete that folder and launch eclipse. That should launch the workspace, but all projects will be gone as org.eclipse.core.resources keeps a list of all projects.

Next, close eclipse properly and copy back org.eclipse.core.resources from back up to .metadata/.plugins/ folder overriding the existing one.

Open eclipse and things should work fine with all your projects back to normal.

Answer 6

deleting workspace/.metadata/.lock and starting eclipse with -clean -refresh worked for me.
