Stopping Jenkins job in case newer one is started

Question

Is it possible to specify that, in case on job (A) is triggered more than once, that previous jobs are removed from queue, and only latest one is left in queue or started if

Answer 1

use execute system groovy script step:

import hudson.model.Result
import jenkins.model.CauseOfInterruption

//iterate through current project runs
build.getProject()._getRuns().each{id,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 = new CauseOfInterruption(){ 
      public String getShortDescription(){
        return "interrupted by build #${build.getId()}"
      }
    }
    exec.interrupt(Result.ABORTED, cause)
  }
}

//just for test do something long...
Thread.sleep(10000)

and in the interrupted job there will be a log:

Build was aborted
interrupted by build #12
Finished: ABORTED
