HI JGit team!

I was trying to use jgit to do a pull or fetch, but i am not able to do it

I tried

My repository is located in a file called test so I did

FileRepositoryBuilder builder = new FileRepositoryBuilder();
Repository repository = builder.setGitDir(new File("test")).readEnvironment().findGitDir().build();
Git git = new Git(repository);
PullCommand pc = git.pull();
pc.call();

And it gave me this error

Pull on repository without HEAD currently not supported

I am not sure what it means,
Please help me out, thanks

Check if the repository you are trying to pull from contains any commits. A fresh empty repository might have HEAD not yet defined. To check this run "git show-ref --head" and check if it lists "HEAD".

Also check this: you should have a currently checkout-out branch in the repo from which you do pull. The error message tells you that we can't resolve the current HEAD in your local repo - the repo into which you want to pull. Maybe it's a very new repo where the master branch is not yet born (no commit has been done yet to master).

Hi Thank you for your reply

The GIT Repository I am using is this
egit.eclipse.org/jgit.git

I was able to do a GIT fetch/pull with TortoiseGUI
With pull I get this
Pull on repository without HEAD currently not supported

With get I get this origin: not found.

If I use fetch setting teh remote location the GIT URL: git.fetch().setRemote("egit.eclipse.org/jgit.git").call();
I got
org.eclipse.jgit.errors.TransportException: Nothing to fetch.
at org.eclipse.jgit.transport.Transport.fetch(Transport.java:1038)

git show-ref --head shows this
Please help me!, THanks!

The URL starts with http, I didn't added because the form showed an error

Found it!

I have to point the File to the .git folder instead of this parent folder!

Case closed, thanks!

This code works!
FileRepositoryBuilder builder = new FileRepositoryBuilder();
Repository repository = builder.setGitDir(new File("test/.git")).readEnvironment().findGitDir().build();
Git git = new Git(repository);
PullCommand pc = git.pull();
pc.call();
