Jenkinsで下流ビルドと上流ビルドを取得する方法

HowToGetDownAndUpstreamBuild.groovy

// あるプロジェクトの下流ビルドと上流ビルドを取得する方法
// 以下は groovy plugin の Execute system Groovy script の中で使用して
// TEST プロジェクトの下流ビルドと上流ビルドを取得する例
def jobname = "TEST"
def job = hudson.model.Hudson.instance.getItem(jobname)
def dep = hudson.model.Hudson.instance.dependencyGraph

assert job, "ERROR: Can't find the job $jobname."
assert dep, "ERROR: Can't get the dependency graph."

def downjobs = dep.getDownstream(job)
def upjobs   = dep.getUpstream(job)

println downjobs.name
println upjobs.name

You could rewrite it as follows:

def jobname = "TEST"
def job = hudson.model.Hudson.instance.getItem(jobname)

assert job, "ERROR: Can't find the job $jobname."

def buildTrigger = job.publishersList.get(hudson.tasks.BuildTrigger)
if (buildTrigger) {
  def childs = buildTrigger.childProjects
  childs.each {
    println it.name
  }
}

Thank you for making my code simpler.

I have found a simpler way to get downstream & upstream jobs.
