Git – How make Eclipse/EGit recognize existing repository information after update

eclipsegit

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?

Best Answer

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

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

Git – Managing large binary files with Git

I discovered git-annex recently which I find awesome. It was designed for managing large files efficiently. I use it for my photo/music (etc.) collections. The development of git-annex is very active. The content of the files can be removed from the Git repository, only the tree hierarchy is tracked by Git (through symlinks). However, to get the content of the file, a second step is necessary after pulling/pushing, e.g.:

$ git annex add mybigfile
$ git commit -m'add mybigfile'
$ git push myremote
$ git annex copy --to myremote mybigfile ## This command copies the actual content to myremote
$ git annex drop mybigfile ## Remove content from local repo
...
$ git annex get mybigfile ## Retrieve the content
## or to specify the remote from which to get:
$ git annex copy --from myremote mybigfile

There are many commands available, and there is a great documentation on the website. A package is available on Debian.

Git – How to move some files from one git repo to another (not a clone), preserving history

If your history is sane, you can take the commits out as patch and apply them in the new repository:

cd repository
git log --pretty=email --patch-with-stat --reverse --full-index --binary -- path/to/file_or_folder > patch
cd ../another_repository
git am --committer-date-is-author-date < ../repository/patch

Or in one line

git log --pretty=email --patch-with-stat --reverse -- path/to/file_or_folder | (cd /path/to/new_repository && git am --committer-date-is-author-date)
