First of all, it is a waste of an executor slot to wrap the build step in node . Your upstream executor will just be sitting idle for no reason. Second, from a multibranch project, you can use the environment variable BRANCH_NAME to make logic conditional on the current branch. Third, the job parameter takes an absolute or relative job name. If you give a name without any path qualification, that would refer to another job in the same folder, which in the case of a multibranch project would mean another branch of the same repository. Thus what you meant to write is probably if (env.BRANCH_NAME == 'master') { build '../other-repo/master' }

Context: How can I trigger build of another job from inside the Jenkinsfile ? I assume that this job is another repository under the same github organization , one that already has its own Jenkins file. I also want to do this only if the branch name is master, as it doesn't make sense to trigger downstream builds of any local branches. Update: stage 'test-downstream' node { def job = build job: 'some-downtream-job-name' } Still, when executed I get an error No parameterized job named
