Eclipse deletes java files on build of an android project

I have an interesting problem. I开发者_运维知识库 pull down an android project from cvs, which works fine. Once Eclipse builds the project, my .java files are removed. XML files, pngs, everything else is fine. I seem to be left with just the package tree, but no source files. Any thoughts?

• Right click on the project
• Properties
• Java Build path
• Source

Check that the src folder path is correct.
