JGIt: pulling across directories. [message #1615041]

Guys, I have been checking out some options and its getting a really big headache to do fairly simple operation.

I have a repository A initialized with JGit, all added and commited.

I do same with other repository in directory B.

Now I am trying to pull all changes from A to B.

In command line it is as simple as git pull ../A

With jgit I have set the config:

config.setString("remote", "local", "url", "file://" + uri);

But... it simply fails saying nothing to fetch. CLI normally fetches everything nicely.

Is there any docs explaining what to do? Can anyone help?

Pete,

you can directly specify the URL to repository B in the pull command
like this:
Git git = Git.open( new File( "/path/to/repo-a" ) );
git.pull().setRemote( "/path/to/repo-b" ).call();
git.close();

Does that work for you? Otherwise please share the code that you use to
pull.

The code that worked was via configuration (no docs to point that out, but luckily git has some):

//uri is absolute FS path
PullCommand p = this.git.pull();
Config config = this.git.getRepository().getConfig();
config.setString("remote", "xxx", "url", "file://" + uri + "");
config.setString("remote", "xxx", "fetch", "+refs/heads/*:refs/remotes/*");
p.setRemote("xxx");
p.setStrategy(MergeStrategy.RECURSIVE).call();

The code I tried is same as you suggested and it was:

PullCommand p = this.git.pull();
p.setRemote(uri);
p.setStrategy(MergeStrategy.RECURSIVE).call();

Exception I receive is:

org.eclipse.jgit.api.errors.InvalidConfigurationException: No value for key remote./Users/peter/bin/repos/out/23423/prod/testrepo.url found in configuration
Fetching and full generating from DB took: 1648ms
at org.eclipse.jgit.api.PullCommand.call(PullCommand.java:247)
at versioning.JGit.pull(JGit.java:138)
at Processor.update(Processor.java:139)
at Main.mainCall(Main.java:139)
at Main.main(Main.java:62)

I think much changed from old api which had File option as argument. I like generic config option but... life is easier with default options (that File argument didnt do any harm to have).

Notice that I have two directories, one is initialized and second one too. They dont have remotes and I wanna pull from one to another (very basic). Its not common use case but this practice is useful in some back-end cases.
