JGit related questions are probably better directed to the
jgit-dev@eclipse.org mailing list, as that is the list most of the
JGit contributors monitor and answer questions on.  The project is
hosted at http://www.eclipse.org/jgit/ so you may find more resources
there too, including the latest 0.10.1 release.

Use the Git object in the org.eclipse.jgit.api package.  There is an
init method that can create a new repository at the given directory.

Try the checkout() method on the Git object.

Try the commit() method on the Git object.

But if you want to avoid using the working directory, you'll need to
go through a much lower-level API, setting up your own DirCache, and
using an ObjectReader and ObjectInserter to interact with the
Repository class.  Doing this requires some knowledge of the basic Git
data model (commits, trees, blobs).
