Jenkins - abort running build if new one is started

With Jenkins script security many of the solutions here become difficult since they are using non-whitelisted methods.

With these milestone steps at the start of the Jenkinsfile, this is working for me:

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

The result here would be:

• Build 1 runs and creates milestone 1
• While build 1 is running, build 2 fires. It has milestone 1 and milestone 2. It passes milestone 1, which causes build #1 to abort.

enable job parallel run for your project with Execute concurrent builds if necessary

use execute system groovy script as a first build step:

import hudson.model.Resultimport jenkins.model.CauseOfInterruption//iterate through current project runsbuild.getProject()._getRuns().iterator().each{ run ->  def exec = run.getExecutor()  //if the run is not a current build and it has executor (running) then stop it  if( run!=build && exec!=null ){    //prepare the cause of interruption    def cause = { "interrupted by build #${build.getId()}" as String } as CauseOfInterruption     exec.interrupt(Result.ABORTED, cause)  }}

and in the interrupted job(s) there will be a log:

Build was abortedinterrupted by build #12Finished: ABORTED 

If anybody needs it in Jenkins Pipeline Multibranch, it can be done in Jenkinsfile like this:

def abortPreviousRunningBuilds() {  def hi = Hudson.instance  def pname = env.JOB_NAME.split('/')[0]  hi.getItem(pname).getItem(env.JOB_BASE_NAME).getBuilds().each{ build ->    def exec = build.getExecutor()    if (build.number != currentBuild.number && exec != null) {      exec.interrupt(        Result.ABORTED,        new CauseOfInterruption.UserInterruption(          "Aborted by #${currentBuild.number}"        )      )      println("Aborted previous running build #${build.number}")    } else {      println("Build is not running or is current build, not aborting - #${build.number}")    }  }}
