Specifying ssh key for jgit

I’m wondering how I can use jgit to connect to github using a specified ssh key file (i.e. one not in ~/.ssh/).

Unfortunately, I’m not sure how to use JschConfigSessionFactory properly. I’ve tried creating a setup just like the one in this article: Using Keys with JGit to Access a Git Repository Securely

    I’ve noticed that the custom overriden methods in JschConfigSessionFactory aren’t ever actually invoked. This is almost certainly the cause of the problem… but don’t know why they’re not invoked; I pass the custom JschConfigSessionFactory to SshSessionFactory using SshSessionFactory.setInstance(sessionFactory);

    Does anybody know what I’m doing wrong?

    GitHub uses password authentication for https URLs and public-key authentication for SSH URLs (see https://gist.github.com/grawity/4392747).

    The SshSessionFactory is only consulted for SSH URLs like git@github.com:user/repo.git. To authenticate for an https URL you can use the CredentialsProvider. The base class for commands that may establish connections is TransportCommand and has a setCredentialsProvider() method.
    If you equip the PushCommand with a CredentialsProvider that supplies user name and password, you should be able to successfully establish a connection.

    For further details about authenticating with JGit you may want to read this article: http://www.codeaffine.com/2014/12/09/jgit-authentication/
