eclipse stuck when building workspace

I am using eclipse 3.4.1 Java EE under Vista. It seems to like getting stuck when building my workspace. Canceling the build doesn't seem to do anything as well.

Why is this happening and how do I fix the problem?

Solution 1:

I was able to fix this with the following:

First, exit Eclipse. Then temporarily move the following .projects folder to a safe location:

mv .metadata\.plugins\org.eclipse.core.resources\.projects projects

Start and exit Eclipse, then move the .projects folder back to where it was originally:

mv projects .metadata\.plugins\org.eclipse.core.resources\.projects

Use at your own risk, of course.

Solution 2:

Some time it's very helpful to execute eclipse from command line with "-clean" parameter to enforce it produce clean up for workspace.
