How to disable automatic build from scm change in Jenkinsfile

Question

I have a Jenkinsfile that I've set up with a cron for a pipelineTriggers parameter. I can't seem to figure out how to disable the job from building from a merge to the master branch of the repo. Is there a way in the Jenkinsfile to disable the automatic build from an scm change?

Answer 1

If you're using a Multibranch Pipeline, you should be able to do this on the job's Configure page:

1. Scroll down to "Branch Sources"
2. Under "Property strategy", choose "Named branches get different properties"
3. Click "Add exception", enter "master" as the branch name
4. Click "Add property", choose "Suppress automatic SCM triggering"
5. Save

That would prevent changes to the master branch from triggering a build of the corresponding job.

Answer 2

For declarative pipelines, use the when directive with a triggeredBy condition, e.g.

when { triggeredBy 'TimerTrigger' }
