This job will run only on master branch and is used to prepare the maintenance/reference branch before doing a release.
Define a new Jenkinsfile to:
- create the maintenance branch matching the current version (11.x, 12.x, ...)
- bump version on the `master` branch.
For instance, triggering this job with the current version being 11.1-SNAPSHOT will do:
- create a 11.x branch
- update the version on master to 12.0-SNAPSHOT
