Eclipse internal error while initializing Java tooling

Question

I am getting errors from Eclipse Indigo running on Windows 7 Ultimate. For each of the following items:

Android SDK content loader
Building workspace
Initial         


        

Answer 1

In my case, I had two of three projects with this problem in my current workspace. I opened workspace catalog and made a backup of corrupted projects, deleted them afterwards. Then opened eclipse once again. Obviously there was missing data to work with. Closed eclipse once again and added back earlier saved projects without metadata catalogs.

TL;DR. Just remove metadata catalogs from projects in your workspace.
