"Build Periodically" with a Multi-branch Pipeline in Jenkins

geowa4 picture geowa4 · Aug 26, 2016 · Viewed 53k times · Source

I'm running Jenkins 2 with the Pipeline plugin. I have setup a Multi-branch Pipeline project where each branch (master, develop, etc.) has a Jenkinsfile in the root. Setting this up was simple. However, I'm at a loss for how to have each branch run periodically (not the branch indexing), even when the code does not change. What do I need to put in my Jenkinsfile to enable periodic builds?

If you use a declarative style Pipeline and only want to trigger the build on a specific branch you can do something like this:

String cron_string = BRANCH_NAME == "master" ? "@hourly" : ""

pipeline {
  agent none
  triggers { cron(cron_string) }
  stages {
    // do something
  }
}
