title: How to disable automatic build from scm change in Jenkinsfile
body: <p>I have a Jenkinsfile that I've set up with a <code>cron</code> for a <code>pipelineTriggers</code> 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?</p>
