Kill all queued jenkins jobs

kill_deploy_jobs.groovy

import hudson.model.*

def q = Jenkins.instance.queue

q.items.each {
  if (it =~ /deploy-to/) {
    q.cancel(it.task)
  }
}

kill_queued_jenkins.groovy

import hudson.model.*

def q = Jenkins.instance.queue

q.items.each { q.cancel(it.task) }

Kill all 'queued deploy' jobs:

import hudson.model.*

def q = Jenkins.instance.queue

q.items.each { 
  if (it =~ /deploy-to/) {
  	q.cancel(it.task)
  }
}

why not just

import hudson.model.*
def queue = Hudson.instance.queue
println "Queue contains ${queue.items.length} items"
queue.clear()
println "Queue cleared"
