JGit SSH support via JSch

This bundle provides an implementation of git transport over SSH implemented via JSch.

This bundle should be considered deprecated. It is essentially unmaintained, and the JGit project may decide anytime to remove it completely without further ado.

The officially supported SSH transport is in bundle org.eclipse.jgit.ssh.apache and is built upon Apache MINA sshd.

Service registration

This bundle declares a service for the java.util.ServiceLoader for interface org.eclipse.jgit.transport.ssh.SshSessionFactory. The core JGit bundle uses the service loader to pick up an implementation of that interface. The bundle in an OSGi fragment to ensure that the service loader works in an OSGi environment without the need to install a service loader bridge.

Note that JGit simply uses the first SshSessionFactory provided by the ServiceLoader.

Using a different SSH implementation

To use a different SSH implementation:

  • Do not include this bundle in your product.
  • Include the bundle of the alternate implementation.
    • If the service loader finds the alternate implementation, nothing more is needed.
    • Otherwise ensure the service declaration from the other bundle is on the Classpath of bundle org.eclipse.jgit,
    • or set the SshSessionFactory for JGit explicitly (see below).

Configuring an SSH implementation for JGit

The simplest way to set an SSH implementation for JGit is to install it globally via SshSessionFactory.setInstance(). This instance will be used by JGit for all SSH connections by default.

It is also possible to set the SSH implementation individually for any git command that needs a transport (TransportCommand) via a org.eclipse.jgit.api.TransportConfigCallback.

To do so, set the wanted SshSessionFactory on the SSH transport, like:

SshSessionFactory customFactory = ...; // Get it from wherever
FetchCommand fetch = git.fetch()
  .setTransportConfigCallback(transport -> {
    if (transport instanceof SshTransport) {
      ((SshTransport) transport).setSshSessionFactory(customFactory);
    }
  })
  ...
  .call();

Using an external SSH executable

JGit has built-in support for not using any Java SSH implementation but an external SSH executable. To use an external SSH executable, set environment variable GIT_SSH to the path of the executable. JGit will create a sub-process to run the executable and communicate with this sub-process to perform the git operation.
