gen already exists but is not a source folder

Question

I am developing my Android project, After I removed a unused library, I got the error:

myproject/gen already exists but is not a source fold         


        

Answer 1

I had SVN configured for a project with the same problem, deleted all folders and files, retrieved it again from SVN and still no luck. The only thing that helped was reverting the changes, and deleting/re-importing projects to the workspace. Hope this helps
