Task element not showing in Stage in Delivery Pipeline View when inside script block

[Joseph Pratt]

Hello all,

I have a question centered around using the "task" method in a script block in a declarative Jenkinsfile. What I'm attempting to do is create a DSL using Groovy where the Jenkinsfile is essentially a config file allowing a dev team to fill in string values and have the declarative pipeline build their projects behind the scenes.

Here's an example Jenkinsfile:

// Jenkinsfile

@Library('pipeline-library') _

project {

   commit {

       buildScript 'build.ps1'

   }

}

vars/project.groovy in the shared 'pipeline-library' would look like this:

// vars/project.groovy

import groovy.transform.Field

import com.foo.*

@Field Closure commitClosure

def call(body) {

   body.resolveStrategy = Closure.DELEGATE_FIRST

   body.delegate = this

   body()

// Declarative pipeline

   pipeline {

       agent any

       stages {

           stage('Commit') {

               steps {

                   script {

                       commitClosure()

                   }

               }

           }

       }

   }

}

def commit(Closure cl) {

cl.resolveStrategy = Closure.DELEGATE_FIRST

cl.delegate = commit

commitClosure = cl

}

and vars/commit.groovy would be:

// vars/commit.groovy

def call(body) {

   body.resolveStrategy = Closure.DELEGATE_FIRST

   body.delegate = this

   body()

}

def buildScript(String str) {

task 'Compile'

powershell str

}

However, since the commit closure is executed in the script block, the task is not showing up in the stage in the Delivery Pipeline view.

First, is there a better way I should be creating the DSL, and second, is it intended that tasks not show up in the stage view when executed from a script block?

Thanks in advanced!

So after further investigation, I found why it wasn't working as expected. The short version is, tasks execute directly in the call() block will not show up in the Delivery Pipeline view
e.g.

def call(body) {

body.resolveStrategy = Closure.DELEGATE_FIRST

body.resolveStrategy = this
// this won't show

task 'Compile'

 body()

}

However, if it is called by the resolution of the closure in another .groovy file, it will show as expected.

This may be a defect, or it may just be due to how Groovy handles closures. Either way, calling it in another .groovy file that is resolved via the previous closure works for me!

Thanks,
Joseph
