Not sure this is the best way, but you may give it a try:

    final Properties config = new Properties();
    config.put("StrictHostKeyChecking", "no");
    JSch.setConfig(config);

    // register a JschConfigSessionFactory that adds the private key as identity
    // to the JSch instance of JGit so that SSH communication via JGit can
    // succeed
    SshSessionFactory.setInstance(new JschConfigSessionFactory() {
      @Override
      protected void configure(Host hc, Session session) {
        try {
          final JSch jsch = getJSch(hc, FS.DETECTED);
          jsch.addIdentity("KeyPair", a.privateKey(),
              a.sshKey.getPublicKeyBlob(), null);
        } catch (JSchException e) {
          throw new RuntimeException(e);
        }
      }
    });
