I tried to restart my computer twice (verify no file is locked).
I tried to remove the server folder.

My latest work isn't committed to SVN.

Any suggestion?

Thanks,

Found a solution!

I deleted the file: /.metadata/.plugins/org.eclipse.core.resources/.snap and it solved the problem.

Thanks!

Great, worked. I had to delete .snap and 36.snap and it worked. – 2sb Jul 11 '16 at 20:32

I think this an error you can't get on it. Try to move all the work in your workspace in a new workspace because it has to do with the bundle, that is the reason it as crashed previously and it won't work on the same workspace

Delete your workspace. Then open eclipse. Take Backup before delete.

Thank you, I didn't realize that starting from scratch will help him solve his problem, but not sure how in any way the problem is solved by doing this, he cannot start eclipse and work in the same context he was working before, this is like saying if your car does not work, throw it away, and buy a new car, strange way of solving things. – tonio Jan 20 '16 at 18:44

I'm running Red Hat Jboss Developer Studio 10.0 (a bundled version of Eclipse), and had this same problem. Deleting the *.snap file in C:\workspace.metadata.plugins\org.eclipse.core.resources worked for me. (This is after an unexpected restart that wouldn't allow me to acknowledge the last Eclipse shut-down pop-up.)

As to why deleting it works, according to What are *.snap files in eclipse?:

"*.snap files represent the changes in workspace state of the IDE during the runtime. This is mostly for eclipse crash recovery plan. When a crash happens these files are used to recover the state of the eclipse workspace."

Apparently, if the crash is severe enough, the snap(shot?) file gets corrupted, and cannot get back to a last good state. But getting Eclipse up at all is better than nothing. You many need to re-import your projects (I had to import my latest one).

Can't open workspace in eclipse
