  to 65709fe44fbe796ba3d301fd155e78be8c7c3b58
  - Remove usage of maven staging plugin

    This plugin will be deprecated soon. We need to remove
    the usage of it and migrate to use gerrit-maven-stage jobs
    from global-jjb.

    After this change is merged, we need to:
    - merge https://gerrit.onap.org/r/#/c/77825/
    - Verify this new job works as expected
    - Remove release-java-daily jobs
