build & current build

get all current build parameters

import hudson.model.*

timestamps { ansiColor('xterm') {
  node('controller') {
    def parameters = currentBuild.rawBuild?.actions.find{ it instanceof ParametersAction }?.parameters
    parameters.each {
      println "parameter ${it.name}:"
      println it.dump()
      println "-" * 80
    }
  }
}}

check previous build status

useful info:

method hudson.model.Run getPreviousBuild
method hudson.model.Run getResult
method org.jenkinsci.plugins.workflow.support.steps.build.RunWrapper getRawBuild

if( ! hudson.model.Result.SUCCESS.equals(currentBuild.rawBuild.getPreviousBuild()?.getResult()) ) {
  echo "last build failed"
}

Stop the current build

stop current

// stop and show status to UNSTABLE
if ( 'UNSTABLE' == currentBuild.result ) {
  currentBuild.getRawBuild().getExecutor().interrupt(Result.UNSTABLE)
}

// stop and show status to NOT_BUILT
if ( 'ABORTED' == currentBuild.result ) {
  currentBuild.rawBuild.executor.interrupt( Result.NOT_BUILT )
}

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

Run previousBuild = currentBuild.getPreviousBuildInProgress()
while ( previousBuild ) {
  if ( previousBuild.isInProgress() && previousBuild.getExecutor() ) {
    println ">> aborting previous build #${previousBuild.number}"
    def cause = { "interrupted by build #${currentBuild.getId()}" as String } as CauseOfInterruption
    previousBuild.getExecutor().interrupt( Result.ABORTED, cause )
  }
  previousBuilds = currentBuild.getPreviousBuildInProgress()
}

abort previous running build

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

def abortPreviousBuilds() {
  Run previousBuild = currentBuild.getPreviousBuildInProgress()

  while (previousBuild != null) {
    if (previousBuild.isInProgress()) {
      def executor = previousBuild.getExecutor()
      if (executor != null) {
        println ">> Aborting older build #${previousBuild.number}"
        def cause = { "interrupted by build #${currentBuild.getId()}" as String } as CauseOfInterruption
        executor.interrupt(Result.ABORTED, cause)
      }
    }
    previousBuild = previousBuild.getPreviousBuildInProgress()
  }
}

or Stopping Jenkins job in case newer one is started

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)

stop all

Thread.getAllStackTraces().keySet().each() {
  t -> if (t.getName()=="YOUR THREAD NAME" ) { t.interrupt(); }          // or t.stop();
}

// and
Jenkins.instance.getItemByFullName("JobName")
                .getBuildByNumber(JobNumber)
                .finish(
                        hudson.model.Result.ABORTED,
                        new java.io.IOException("Aborting build")
                );

How to time out Jenkins Pipeline stage and keep the pipeline running?

`warnError`

node( 'controller' ) {
  warnError( 'Script failed!' ) {
    sh( 'false' )
  }
}

`catchError`

stage( 'false' ) {
  catchError(
    buildResult : 'SUCCESS',
        message : 'stage failed, but build succeed',
    stageResult : 'FAILURE'
  ){
    sh label: env.STAGE_NAME,
       script: 'exit 2'
  }
}

or just be simply:

 catchError( buildResult: 'SUCCESS', stageResult: 'FAILURE' ) {
   sh( 'false' )
 }

set unstable

catchError( message: 'script failed', buildResult: 'UNSTABLE', stageResult: 'UNSTABLE' ) {
  sh( 'false' )
}

catchError unstable

`error`

Signals an error. Useful if you want to conditionally abort some part of your program. You can also just throw new Exception(), but this step will avoid printing a stack trace

error( 'failed the build' )

`unstable`

Prints a message to the log and sets the overall build result and the stage result to UNSTABLE. The message will also be associated with the stage result and may be shown in visualizations.

unstable( 'unstable the build' )

get stage of a build

get stage name

stage( 'build' ) {
  println "${env.STAGE_NAME}"
}

get all stages of a build

WorkflowRun run = Jenkins.instance.getItemByFullName("####YOUR_JOB_NAME####")._getRuns()[0]
