How make Eclipse/EGit recognize existing repository information after update?

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.

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 .git subdirectory, but Eclipse seems to treat each project as if it wasn't a git repository already.

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?

Thanks to Jeremy, i found how to reactivate the repos myself. Basically, two steps were required:

1. Add the (already existing) local repository to EGit's Git Repositories view;
2. "Share" each of the projects again using "use or create repository".

The second step won't work if the repo isn't available in the repository view. So, after an eclipse upgrade, do the following:

Add the (already existing) local repository to EGit's Git Repositories view

• Open the Git Repositories view:
• Hit the "add" button (Tooltip: Add an existing local Git Repository to this view)
• In the "Add Git Repositories" dialogue, under Search criteria, enter the workspace directory, select "Look for nested repositores", and hit Search:
• Select the repositories you want to add and click OK

"Share" each of the projects again using "use or create repository"

• Open you existing project in Eclipse's Project explorer;
• Right-click and select "Team -> Share Project...":

• Select Git Project, and in the next dialogue, select "Use or create Repository in parent folder of project". Important: don't try to select the repository from the combo box that's visible when "Use or create Repository in parent folder of project" isn't selected - it won't work.

  

The wizard suggests the local git repository that's located in the current project, so just hit Finish.

Even after adding git repos I cannot do Team/Share on project, but what helped was to close and open project - you can also select multiple projects so action is quick

In my case, the git repos existed but the team context did not show the "Share this project" option. It looked like the project was partially configured with git.

I could fix the problem by deleting the project (without deleting the actual files) and then importing the project back to eclipse.
