We use a fork of jenkins-job-builder via the Gerrit repository integration/jenkins-job-builder.git Gerrit repository.
It had a cherry pick of a patch I have made years ago: https://review.opendev.org/#/c/471030/1 which I have dropped some minutes ago (it is no more needed). Our fork is now pointing at tag 2.0.2.
We should just use pypi for now until we gotta fork again. Then proceed with catching up upstream.
