Set the pipeline name and description from Jenkinsfile

You need to use currentBuild like below. The node part is important

node {    currentBuild.displayName = "$yournamevariable-$another"    currentBuild.description = "$yourdescriptionvariable-$another"}

Edit: Above one renames build where as Original question is about renaming jobs.Following script in pipeline will do that(this requires appropriate permissions)

item = Jenkins.instance.getItemByFullName("originalJobName")item.setDescription("This description was changed by script")item.save()item.renameTo("newJobName")

I'm late to the party on this one, but this question forced me in the #jenkins chat where I spent most of my day today. I would like to thank @tang^ from that chat for helping solve this in a graceful way for my situation.

To set the JOB description and JOB display name for a child in a multi-branch DECLARATIVE pipeline use the following steps block in a stage:

steps {    script {        if(currentBuild.rawBuild.project.displayName != 'jobName') {            currentBuild.rawBuild.project.description = 'NEW JOB DESCRIPTION'            currentBuild.rawBuild.project.setDisplayName('NEW JOB DISPLAY NAME')        }        else {            echo 'Name change not required'        }    }}

This will require that you approve the individual script calls through the Jenkins sandbox approval method, but it was far simpler than anything else I'd found across the web about renaming the actual children of the parent pipeline. The last thing to note is that this should work in a Jenkinsfile where you can use the environment variables to manipulate the job items being set.

I tried to used code snippet from accepted answer to describe my Jenkins pipeline in Jenkinsfile. I had to wrap code snippet into function with @NonCPS annotation and use def for item variable. I have placed code snippet in root of Jenkinsfile, not in node section.

@NonCPS def setDescription() {     def item = Jenkins.instance.getItemByFullName(env.JOB_NAME)     item.setDescription("Some description.")     item.save()}setDescription()
