How to make Pipeline job to wait for all triggered parallel jobs?

Question

I\'ve Groovy script as part of the Pipeline job in Jenkins as below:

node {
    stage(\'Testing\') {
        build job: \'Test\', parameters: [string(name: \         


        

Answer 1

This works for me. Triggers 3 jobs. Wait for them to finish. Pay attention to the extra "->" to specify groovy closure. I have one -> on the each loop, and one on the parallel line. It means that the value will be evaluated when running the parallel section.

def jobsString = "job1,job2,job3"
ArrayList jobsList = jobsString.split('\\,')

def parallelJobs2Run = [:]
jobsList.each { job ->
    echo "Going to parallel for job ${job}"
    parallelJobs2Run["${job}"] = { ->
        echo "Calling job ${job}"
        jobResults=build job: "${pathJenkinsFolder}${job}",
        parameters: [
            string(name: 'param1', value: "${value1}"),
            string(name: 'param2', value: "${value2}")
        ],
        propagate: true,
        wait: true

        // List of values: https://stackoverflow.com/questions/46262862/how-to-i-get-the-url-of-build-triggered-with-build-step-on-jenkins
        buildNumber = ${jobResults.number}
        echo "${job} Build number |${buildNumber}| result: |${jobResults.result}|"
        echo "See details on: |${jobResults.absoluteUrl}|"
    }
};
parallel parallelJobs2Run

You should use pipeline parallel expression, which will wait for all spawned jobs / subtasks to complete:

stage('testing') {
    def branches = [:]

    for(i = 0; i < params.size(); i += 1) {
        def param = params[i]

        branches["Test${i}"] = {
            build job: 'Test', parameters: [string(name: 'Name', value: param)], quietPeriod: 2
        }
    }
    parallel branches
}

You can find some more examples in pipeline docs at jenkins.io

Just run into the same problem, and find a working solution. Just use foreach.

stage('testing') {
    def jobs = [:]

    [1,2,3,4,5].each{
        i -> jobs["Test${i}"] = {
            build job: 'Test', 
            parameters: [string(name: 'theparam', value: "${i}")],
            quietPeriod: 2
        }
    }
    parallel jobs
}

However @agg3l's example is not working with multiple jobs.

Map jobResults = [:]

Boolean failedJobs = false
def buildJobWithParams(def jobs_list, Map results) {
  def branches = [:]    
  for(job in jobs_list)
  {
    print job
    branches["Test-${job}"] = {
       def jobBuild = build job: job, propagate: false
       def jobResult = jobBuild.getResult()
       echo "Build of '${job}' returned result: ${jobResult}"
       results[job] = jobResult
    }
  }    
  return branches
}

stage('Run integration tests') {
      steps {
            def job_branch = buildJobWithParams(item_list, jobResults)
            print job_branch
            parallel job_branch
          }
}

The item_list has more than 1 job, however it will execute only last job multiple times.
