Temporarily disable SCM polling on Jenkins Server in System Groovy

You could disable only those jobs which have an SCM polling trigger. This groovy script will do that:

Hudson.instance.items.each { job ->  if ( job.getTrigger(  hudson.triggers.SCMTrigger ) != null ) {    println "will disable job ${job.name}"    job.disable()  }}

Re-enabling the jobs will be left as an exercise : )

1. If it is one or 2 builds that are configured to do SCM polling, you can go into the configuration of each build and uncheck the box. It is that simple :)

2. If you are using jenkins job builder, it should be even easier to change the configuration of several jobs at a time.

3. If you using slaves or even on master, SCM polling is dependent on JAVA ? remove JAVA from the machine temporarily from the location where it is configured in master jenkins ;) The polling will fail :P This is a stupid hack ;)

I hope that helps !! ?

Try following Groovy script to comment out SCM Polling:

// WARNING: Use on your own risk! Without any warranty!import hudson.triggers.SCMTriggerimport hudson.triggers.TriggerDescriptor// from: https://issues.jenkins-ci.org/browse/JENKINS-12785TriggerDescriptor SCM_TRIGGER_DESCRIPTOR = Hudson.instance.getDescriptorOrDie(SCMTrigger.class)assert SCM_TRIGGER_DESCRIPTOR != null;MAGIC = "#MAGIC# "// comment out SCM Triggerdef disable_scmpoll_trigger(trig){   if ( !trig.spec.startsWith(MAGIC) ){    return new SCMTrigger(MAGIC + trig.spec)  }  return null  }// enable commented out SCM Triggerdef enable_scmpoll_trigger(trig){   if ( trig.spec.startsWith(MAGIC) ){    return new SCMTrigger(trig.spec.substring(MAGIC.length()))  }  return null  }Hudson.instance.items.each {  job ->   //println("Checking job ${job.name} of type ${job.getClass().getName()} ...")  // from https://stackoverflow.com/a/39100687  def trig = job.getTrigger( hudson.triggers.SCMTrigger )  if ( trig == null ) return  println("Job ${job.name} has SCMTrigger: '${trig.spec}'")  SCMTrigger newTrig = disable_scmpoll_trigger(trig)  // SCMTrigger newTrig = enable_scmpoll_trigger(trig)  if (newTrig != null ){    newTrig.ignorePostCommitHooks = trig.ignorePostCommitHooks    newTrig.job = job    println("Updating SCMTrigger '${trig.spec}' -> '${newTrig.spec}' for job: ${job.name}")    job.removeTrigger(SCM_TRIGGER_DESCRIPTOR)    job.addTrigger(newTrig)    job.save()  }    }return ''

To enable SCM polling again just change these two lines

  //SCMTrigger newTrig = disable_scmpoll_trigger(trig)  SCMTrigger newTrig = enable_scmpoll_trigger(trig)

Tested on Jenkins ver. 2.121.3

Known limitations:

• supports single line "Schedule" (spec property) only
