title: How make Eclipse/EGit recognize existing repository information after update?
body: <p>After upgrading Eclipse from Helios to Indigo with EGit plugin 1.0.0, all my projects seem to have lost their metadata about their git repositories, respectively.</p>
  
  <p>In Helios, every Eclipse project was a git repository on its own. When updating to Indigo, i hoped i could continue using the workspace from Helios. After the update, all projects are still present in the workspace; and in each project directory, there's still the <code>.git</code> subdirectory, but Eclipse seems to treat each project as if it wasn't a git repository already.</p>
  
  <p>So, there's still all git metadata in the project folders, but eclipse doesn't recognize them. Is there another way to "reactivate" the git functionality?</p>
