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?

Right click on a project and go to Team. Does it have the usual Git stuff, or does it allow you to "share" the project? If it says "share", then just set it up again. – Jeremy
@Jeremy: I tried this already - the usual git stuff is missing there, that's exactly the problem. Furthermore, using "share" doesn't allow me to use the repository that already exists in the project folder (using gitk on that folder works perfectly fine...). Using "share", i could clone that repo, but i don't want to clone it, i want to use it from within Eclipse. – tohuwawohu
Are you able to click on the checkbox that says "User or create Repository..." and select it? – Jeremy
@Jeremy: thanks a lot, now it works. I had to set the local repositories up again before using "Team -> Share... -> Use Repository". After adding them to the Git Repositores view, eclipse allowed me to "activate" them as you described. – tohuwawohu
I have identified some generic steps to reproduce this (not only after Eclipse upgrades) and opened a bug report. Feel free to upvote it to help it get prioritised. – Pyves

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

    select repository to use

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.
