Porcelain API

While JGit contains a lot of low level code to work with Git repositories, it also contains a higher level API that mimics some of the Git porcelain commands in the org.eclipse.jgit.api package.

Most users of JGit should start here.

AddCommand (git-add)

AddCommand allows you to add files to the index and has options available via its setter methods.

• addFilepattern()

Here's a quick example of how to add a set of files to the index using the porcelain API.

Git git = new Git(db);
AddCommand add = git.add();
add.addFilepattern("someDirectory").call();

CommitCommand (git-commit)

CommitCommand allows you to perform commits and has options available via its setter methods.

• setAuthor()
• setCommitter()
• setAll()

Here's a quick example of how to commit using the porcelain API.

Git git = new Git(db);
CommitCommand commit = git.commit();
commit.setMessage("initial commit").call();

TagCommand (git-tag)

TagCommand supports a variety of tagging options through its setter methods.

• setName()
• setMessage()
• setTagger()
• setObjectId()
• setForceUpdate()
• setSigned() - not supported yet, will throw exception

Here's a quick example of how to tag a commit using the porcelain API.

Git git = new Git(db);
RevCommit commit = git.commit().setMessage("initial commit").call();
RevTag tag = git.tag().setName("tag").call();

LogCommand (git-log)

LogCommand allows you to easily walk a commit graph.

• add(AnyObjectId start)
• addRange(AnyObjectId since, AnyObjectId until)

Here's a quick example of how get some log messages.

Git git = new Git(db);
LogCommand log = git.log().call();

MergeCommand (git-merge)
