      Hi,

      I've tried to switch to the next (unreleased) version of the Git plugin, in order to integrate with Jenkins credentials repository.

      I've selected:

      • Repository: git@github.com:ORG/PROJECT.git
      • Credentials: <A ssh deploy key linked to that project>
      • Git executable: JGit
      • Activate SSH Agent with the same credentials

      The SSH key isn't set as the "default key" of the Jenkins shell user on the server.

      As a result, Git SCM Polling, Github web hook and pre-build fetch fail.
      When I switch back to the "native" git executable, polling and web hook fail (as usual), but pre-build fetch succeed.

      Here is the stack trace I get:
