Eclipse will not start and I haven't changed anything

Solution 1:

I used eclipse -clean -clearPersistedState and that worked for me. You will lose your window layout configuration, but that seems minor to me.

For Linux systems try: ./eclipse -clean -clearPersistedState

Solution 2:

Ok so i figured it out. Go to yourWorkspace/.metadata/.plugins and delete everything in there. Eclipse will start and repopulate the folder.

Solution 3:

Removing workbench.xmi under workspace/.metadata/.plugins/org.eclipse.e4.workbench/ worked for me. It did not remove the existing projects.

Solution 4:

This works like champ on mac os or windows.

Remove workbench.xmi located at workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi. Then start your Eclipse or ADT. This will not erase your workspace or repository.

Remove workbench.xmi cmd:

rm workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi.
