As of now I believe that repo is
          the test repo for the p2 migration. Although if you are seeing
          strangeness with it then it may indicate a problem encountered
          when they did the test migration to create the repo.

          Guys,
          
          
          Is
            git.eclipse.org/gitroot/equinox/rt.equinox.p2.git supposed
            to be ready to use?
          
          I
            tried cloning it and the operation seems to finish
            successfully but afterwards most of the projects (when
            imported in Eclipse) don’t compile properly.
          For
            example p2.repository doesn’t see some of the exported
            packages by p2.core.
          
          Any
            idea what’s wrong? 
          
          Thanks,
          Katya
