Parallel jobs using build flow plugin with loop in jenkins

parallel takes a list of Closures, so you should be able to use collect to return a list:

import jenkins.model.Jenkinsimport java.util.regex.*Pattern myRegex = ~/release_status.*/parallel jenkins.model.Jenkins.instance.items.collect { item ->    { ->         if (item.name ==~ myRegex) {            build( "$item.name" )        }    }}

An alternative that only returns a Closure if the name passes (rather than a Closure for every item, a lot of which will finish early) is:

import jenkins.model.Jenkinsimport java.util.regex.*Pattern myRegex = ~/release_status.*/parallel Jenkins.instance.items.findAll { item -> item.name ==~ myRegex}                               .collect { item -> { -> build("$item.name") } }

Here is my solution that might be helpful with Folders plugin:

import jenkins.model.Jenkins//Configuration blockdef dryRun = truedef projectFolder = 'Path/To/Folder'def phases = ['.*-Build','.*-Deploy', '.*-Regression', '.*Service-Full-Performance-Test']//Configuration blockdef phasesRegex = []phases.each{  phasesRegex.push(~/${projectFolder}\/${it}/)}def jobs = []items = jenkins.model.Jenkins.instance.getItemByFullName(projectFolder);items.getAllJobs().collect{  jobs.push(it.getFullName())}phasesRegex.each{  run = jobs.grep(it)  parallel run.collect{ job ->    { ->      if (dryRun) println "Dry Run of Job: ${job}"      else build(job)    }  }}
