Description Markus Keller

Eclipse 3.6.2
J/EGit 1.2.0.201110021920

After killing Eclipse in bug 360133, I cannot use "Team > Reset > Hard" any more, since I always get the error below.

I found bug 350677 comment #1:
> To worksround the issue you can delete the lock file (index.lock).
> It is contained in the .git directory.

This worked, but I shouldn't have to know that as an EGit user.

You are right, EGit should be more user friendly here and ask the user if he killed git earlier which may result in such a zombie index.lock file, and if he wants to remove this stale lock file.

Just got hit by this also.

Isn't it a dupe of bug 339781?
