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.
integration/config.git uses:
git+https://gerrit.wikimedia.org/r/integration/jenkins-job-builder.git@master#egg=jenkins_job_builder
We should just use pypi for now until we gotta fork again. Then proceed with catching up upstream.
