@xmass Is this still valid? I see a lot of work here and want to make sure it is adequately tracked
Is there an associated Github issue with this PR? What about a Jenkins jira? If so, can you link them? If not, can you open them and note this PR?
Thank you for that.
I am coming onboard as a maintainer and link to make sure we keep as much details across the Jenkins spectrum as well.
Thanks again :-)

Going to need to fix the ci build job

The goal was to use it instead of gitlabBuilds to set pending status to git defining git repository and commit parameters which the gitLabBuilds doesn't have. To modify gitLabCommitStatus was easier for me.
The problem I'm trying to adders here is when you start the pipeline the gitLabBuilds might not have the correct information about the git repository and which commit shall be used and often it confuses it with git repository of shared library. This solution I would call as workaround to missing functionality of gitlabBuilds and should be inherited by someone who understands better the code of gitLabBuilds and add the option to have possibility to set the git repository and commit.
