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: 'Name', value: 'Foo1')], quietPeriod: 2, wait: false         build job: 'Test', parameters: [string(name: 'Name', value: 'Bar1')], quietPeriod: 2, wait: false         build job: 'Test', parameters: [string(name: 'Name', value: 'Baz1')], quietPeriod: 2, wait: false         build job: 'Test', parameters: [string(name: 'Name', value: 'Foo2')], quietPeriod: 2, wait: false         build job: 'Test', parameters: [string(name: 'Name', value: 'Bar2')], quietPeriod: 2, wait: false         build job: 'Test', parameters: [string(name: 'Name', value: 'Baz2')], quietPeriod: 2, wait: false     } } 

which executes multiple other freestyle jobs in parallel, because of wait flag being set to false. However I'd like for the caller job to finish when all jobs are finished. Currently the Pipeline job triggers all the jobs and finishes it-self after few seconds which is not what I want, because I cannot track the total time and I don't have ability to cancel all triggered jobs at one go.

How do I correct above script for Pipeline job to finish when all jobs in parallel are completed?

I've tried to wrap build jobs in waitUntil {} block, but it didn't work.

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 }
