How to get latest build number from another job in jenkins pipeline

Question

I am using jenkins pipeline 2.0, and I would like to get another job's latest successful build number.

What's the pipeline syntax to use?

Answer 1

You can get it this way

def buildNumber = Jenkins.instance.getItem('jobName').lastSuccessfulBuild.number

If you get a RejectedAccessException you will have to approve those methods, see In-process Script Approval
