Java Project Git Tag Changed From master to NO-HEAD [message #1584958]

I have a number of Java projects that have been added to eGit. The git repository for each project resides in a directory GitRepositories. For a project Foo, the git repository is located in .../GitRepositories/Foo.

Many of the projects have a short history of commits after the initial commit. In the package explorer, after the projects were initially committed, eGit displays a short string next to the project (e.g. [Foo master]).

For some of my projects, the short string next to the project has now changed to [GitRepositories NO-HEAD]. When a change is made to a file in the project, you no longer get the > next to the file when the code change is saved.

If you right click on the project, select Properties and select Git, the project would have originally displayed:

Git directory: .../GitRepositories/Foo/.git
Working directory: .../GitRepositories/Foo

Now some of the projects display:

Git directory: .../GitRepositories/.git
Working directory: .../GitRepositories

The directory structure of the git repositories has not changed.

Anybody know what has happened? More important, does anybody know how to get the project configured correctly?

This happens if the repository's HEAD (pointer to the currently checked out branch, sometimes to
a directly checked out commit or tag) is missing or points to nowhere.

Does your repository's .git folder contain a file named "HEAD" ? If yes, what's the content of this file ?
What's the output of "git status" on this repository ?

What seems to have happened is that eGit now mistakenly thinks that project Foo is in directory .../GitRepositories rather than the proper .../GitRepositories/Foo.

There is a .../GitRepositories/.git, which is nonsensical since GitRepositories contains multiple separately controlled projects. It appears to have been created on January 17. It is a mostly empty hierarchy of directories. The HEAD file contains:

ref: refs/heads/master

There is no refs/heads/master file.

If I look at one of my projects (e.g. .../GitRepositories/Foo), there is a .git directory there as expected and proper. The HEAD file also contains:

ref: refs/heads/master

In this case however, there is a refs/heads/master file that contains a proper object reference: 6b2ae59c7bb853ea8fdbf9c7e4a38a8f937c869a.

Another interesting symptom is that Eclipse seems to know that the project is in .../GitRepositories/Foo. I had first noticed something was wrong when a file edit on a previously committed file did not result in the > being displayed in front of the file name to indicate that a commit was needed. I have discovered though that Eclipse has been happily storing the updates in the proper source code file in .../GitRepositories/Foo/Foo/src/com/...

I have resolved the problem.

I right clicked on the project and used Team -> Disconnect to disconnect eGit from the repository. I then right clicked on the project and used Delete (without removing project content from disk!!!) to remove the project from Eclipse.

I then used the Eclipse File menu to import a Git project from an existing local repository (.../GitRepositories/Foo/.git).

Once I had done this for all of my projects, I deleted the empty .../GitRepositories/.git directory that had mysteriously been created.

I still don't know how the problem occurred in the first place. I had upgraded to Luna recently, but I am not sure if I had done this near the time when this problem showed up.
