SCM Poll in jenkins multibranch pipeline

Question

Wanted to accommodate scheduled build starting 12AM every 3 hrs till 3PM on every weekday(mon-fri). It should be triggered build only if anything is committed into github repository.

Please provide the exact code as few code is working for multi-branch but not for above schedule.

Answer 1

Sorry what do you mean by the scheduled "build"?

1. Do you want the Multi-Branch to check for more branches on your given interval?

If so you can only do it by "Scan Multibranch Pipeline with defaults Triggers"

2. Do you want to issue a build on the branch when there is change on it?

Noted that the option in

the mult-branch folder > "Scan Multibranch Pipeline with defaults Now" and get all current branches > status > the jobs > View Configuration

is read only.

So, to alter the option, from https://issues.jenkins-ci.org/browse/JENKINS-33900?focusedCommentId=326181&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-326181 , I think you should use the Jenkinsfile to do theSCM for every job.

So, for all jobs you need to configure for SCM poll, include a Jenkinsfile on Git for each of them (Don't forget to install the pipeline-model-definition plugin and all its dependent plugins):

pipeline {
  triggers {
        pollSCM('H 0-15/3 * * H(1-5)')
           }
    agent any
    stages{
        stage('Build') {
            steps {
            echo 'Building.. or whatever'
            }
        }
    }

}

That should do the job, at least it works for me``

Hope it helps
