      The meta-ref of a change (e.g refs/changes/1/1/meta) might not be replicated with the same push as the patchset (e.g. refs/changes/1/1/1), but later. If Jenkins tries to clone from the Gerrit replica, Gerrit will try to check the users permission to read that revision and fails, because it requires the meta-ref to build the change notes. In the Gerrit logs this looks like:

      Thus, the gerrit-trigger plugin should ensure that both the patchset ref and meta-ref were replicated.
