Can I use a Closure to define a stage in a Jenkins Declarative Pipeline?

Question

I\'m trying to do something like this:

def makeStage = {
  stage(\'a\') {
    steps {
      echo \'Hello World\'
    }
  }
} 
pipeline {
  agent none
  stage

Super late, but in case anyone runs into this issue, a possible solution would be to wrap your generated stage around a script declarative and invoke .call on the generated stage.

So for you:

def makeStage = {
  return {
    stage('a') {
      echo 'Hello World'
    }
  }
}

pipeline {
  agent none
  stages {
    stage ('hello world') {
      steps {
        script {
          makeStage().call()
        }      
      }
    }
  }
}

Whoops. edited, I had "steps" inside on my stage('a') in the makeStage declaration. "steps" is a declarative pipeline directive so it was throwing an error inside the script block.
