Eclipse quit unexpectedly (Mac OS X 10.7.4 and Eclipse 3.8)
This is probably because eclipse shutdown abnormally. Open the Terminal and go to the location where eclipse is installed.
cd /Applications/Eclipse.app/Contents/MacOS
Then run eclipse from the terminal like...
./eclipse -clean
It should start, once it does go to the Eclipse menu and Quit eclipse.
If you have any shortcuts on the desktop you'll have to remove them and make new shortcuts with the executable.
I had the same problem on my Mac running OS X Mountain Lion 10.8.2.
I tried:
- Installing/updating to the newest version of Sun Java.
- Re-downloading a different Eclipse Package.
- Re-installing Eclipse.
None of these things worked. I was using The Unarchiver 3.3 to unarchive the tar.gz archive—this was the problem. I right clicked the archive and selected Open With → Archive Utility.app (10.8). Then I dragged the unarchived folder to Applications and now Eclipse runs. Seems The Unarchiver was corrupting a file. Very strange, The Unarchiver has never let me down before but this seems to be the problem.
