How can I trigger another job from a jenkins pipeline jenkinsfile with GitHub Org Plugin

Question

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 some-downtream-job-name found   I am sure that this job exists in jenkins and is under the same organization folder as the current one  It is another job that has its own Jenkinsfile   Please note that this question is specific to the GitHub Organization Plugin which auto-creates and maintains jobs for each repository and branch from your GitHub Organization

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

In addition to the above mentioned answers  I wanted to start a job with a simple parameter passed to a second pipeline and found the answer on http   web archive org web 20160209062101 https   dzone com refcardz continuous-delivery-with-jenkins-workflow So i used  stage   Starting ART job         build job   RunArtInTest   parameters     class   StringParameterValue   name   systemname   value  systemname

Use build job plugin for that task in order to trigger other jobs from jenkins file  You can add variety of logic to your execution such as parallel  node and agents options and steps for triggering external jobs  I gave some easy-to-read cookbook example for that    1 example for triggering external job from jenkins file with conditional example   if  env BRANCH NAME     master       build job  exactJobName    parameters       string name   keyNameOfParam1  value   valueOfParam1       booleanParam name   keyNameOfParam2  value  valueOfParam2          2 example triggering multiple jobs from jenkins file with conditionals example    def jobs         job1Title       if  env BRANCH NAME     master           build job  exactJobName    parameters           string name   keyNameOfParam1  value   valueNameOfParam1           booleanParam name   keyNameOfParam2  value  valueNameOfParam2                        job2Title       if  env GIT COMMIT     someCommitHashToPerformAdditionalTest           build job  exactJobName    parameters           string name   keyNameOfParam3  value   valueOfParam3           booleanParam name   keyNameOfParam4  value  valueNameOfParam4           booleanParam name   keyNameOfParam5  value  valueNameOfParam5

The command build in pipeline is there to trigger other jobs in jenkins   Example on github  The job must exist in Jenkins and can be parametrized  As for the branch  I guess you can read it from git
