Issue

You have a Pipeline or Pipeline Multibranch job, and you want the running job to be aborted automatically if a new run is started. This can be useful if a new commit is made to the same branch of a project, and therefore you have no need to continue building the previous commit.

Environment

• CloudBees CI (CloudBees Core)
• CloudBees CI (CloudBees Core) on modern cloud platforms - Managed Master
• CloudBees CI (CloudBees Core) on modern cloud platforms - Operations Center
• CloudBees CI (CloudBees Core) on traditional platforms - Client Master
• CloudBees CI (CloudBees Core) on traditional platforms - Operations Center
• CloudBees Jenkins Enterprise
• CloudBees Jenkins Enterprise - Managed Master
• CloudBees Jenkins Enterprise - Operations Center
• CloudBees Jenkins Platform - Client Master
• CloudBees Jenkins Platform - Operations Center
• CloudBees Jenkins Distribution
• CloudBees Jenkins X Distribution
• Jenkins LTS

Resolution

The best way to accomplish this is through some simple scripted Pipeline at the start of your Jenkinsfile:

def buildNumber = env.BUILD_NUMBER as int
if (buildNumber > 1) milestone(buildNumber - 1)
milestone(buildNumber)

The outcome of this is that build #1 will create milestone1 in the project. While build #1 is running, if build #2 is started, it will create milestone1 and milestone2 in the project. Build #2 will immediately pass milestone1 and will therefore cause Build #1 to abort.

JENKINS-43353 tracks a feature request to make this a core feature of Pipeline, but the above workaround is the most efficient solution available currently.
