Running stages in parallel with Jenkins workflow / pipeline

Question

Please note: the question is based on the old, now called \"scripted\" pipeline format. When using \"declarative pipelines\", parallel blocks

Answer 1

that syntax is now deprecated, you will get this error:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 14: Expected a stage @ line 14, column 9.
       parallel firstTask: {
       ^

WorkflowScript: 14: Stage does not have a name @ line 14, column 9.
       parallel secondTask: {
       ^

2 errors

You should do something like:

stage("Parallel") {
    steps {
        parallel (
            "firstTask" : {
                //do some stuff
            },
            "secondTask" : {
                // Do some other stuff in parallel
            }
        )
    }
}

Just to add the use of node here, to distribute jobs across multiple build servers/ VMs:

pipeline {
  stages {
    stage("Work 1"){
     steps{
      parallel ( "Build common Library":   
            {
              node(''){
                  /// your stuff
                  }
            },

        "Build Utilities" : {
            node(''){
               /// your stuff
              }
           }
         )
    }
}

All VMs should be labelled as to use as a pool.
