Jenkins – Accessing the current Jenkins build in Groovy script

groovyJenkins

I have created a Groovy script which is used in a System Groovy Script step in a Jenkins job which needs to access the current build of the current job.

The current build is required when using an Hudson.model Cause.UpstreamCause to link the current build of my current job to a dependent job that I am scheduling.

Since code is more concise:

my-job-step.groovy:

def scheduleDependentJob(jobName) {
  def fooParam = new StringParameterValue('foo', 'bar');
  def paramsAction = new ParametersAction(fooParam)

  println "Scheduling dependent job"
  def currentJob = ???
  def cause = new Cause.UpstreamCause(currentBuild)
  def causeAction = new hudson.model.CauseAction(cause)
  instance.queue.schedule(job, 0, causeAction, paramsAction)
}

The CauseAction constructor (Seen on http://javadoc.jenkins-ci.org/hudson/model/Cause.UpstreamCause.html) requires a Run object, which the current build object should be an instance of. I just can't find a good way to get the current running job build inside of a Groovy script.

If in your Jenkins job you are using Groovy plug-in, then inside Execute system Groovy script step the plug-in already provides you access to some predefined variables:

build
    The current AbstractBuild.
launcher
    A Launcher.
listener
    A BuildListener.
out
    A PrintStream (listener.logger).

For example:

println build.getClass()

Outputs:

class hudson.model.FreeStyleBuild
