Sudden weird errors on a project-Collection of common programming errors

I have went through that problem a lot of times, and tried everything you tried. Rebuild, recompile, refresh, remove and add JDK, remove and reinstall Eclipse… nothing worked

The only thing I concluded is that the workspace metadata was corrupted.

What I did (every time it happened) was

• Create an empty workspace
• Import -> existing projects into worskpace
• Mark the “copy projects” (else it will only link them)
• Wait for the copy, and start working with the new workspace

If you work with SCM systems (Git, SVN, etc), making a full checkout will do the trick too, but the worskpace import will let you retrieve those changes you didn’t get to commit (if any).

It’s a little painful if you have somethings already set (like JDK names, servers, etc), but then I realized it was faster than keep searching how to fix the workspace

Regards!

PS : I’ve been working with Kepler lately, and everything works fine till now
