Dynamic stages in pipeline

[Arnaud Brunet]

Hi guys,

I try to make a pipeline script with dynamic stages.

In static way, I do

pipeline {
  agent any
  options {
    timestamps()
  }
  stages {
    stage('Init') {
      steps {
        script {
          echo "TOTO"
        }
      }
    }
  }
}

but I want my stages to be dynamic, something like that :

def jobStages = [

  'init': {

     echo "Init"

  }

]

pipeline {

  agent any

  options {

    timestamps()

  }

  stages {

    jobStages.each { name, closure ->

      stage(name) {

        steps {

          script {

            closure.call()

          }

        }

      }

    }

  }

}

But Jenkins doesn't like it :

/var/lib/jenkins/jobs/AXI-TEST-Pipeline Script/builds/79/libs/jenkins-shared-libs/vars/standardBuild.groovy: 27: Expected a stage @ line 27, column 13.
               jobStages.each { name, closure ->
               ^

/var/lib/jenkins/jobs/AXI-TEST-Pipeline Script/builds/79/libs/jenkins-shared-libs/vars/standardBuild.groovy: 26: No stages specified @ line 26, column 9.
           stages {
           ^

Is there a way to do this ?

Regards,

Arnaud.

I think with the declarative syntax all of the "scaffolding" (stages, post, when) bits have to be set in stone.

This recent thread might be slightly relevant

It is good of what I thought. Thank you for the confirmation.
