Hiding in Plain Sight: Unmasking the Jenkins DSL
summary
Claims that Jenkins already exposes the real DSL as the structured form submission JSON and that YAML can express it; shows a yaml project plugin that reads checked-in YAML, lazily binds objects, supports tag shorthand for plugin classes, and instantiates jobs on change; demos convert a freestyle job to a Matrix job, run builds via Git branches, and integrate with the multi-branch integration so branches get their own job configs; engineers report twice as many feature branches and <10% of config still on the master, and the demos work end-to-end.
