Problems with creating a pipelineJob environment variables via groovy script

Question

does this https://jenkinsci.github.io/job-dsl-plugin/#path/pipelineJob-environmentVariables-groovy actually work?

Probably more of an plugin issue.

groovy scripts to set env vars seem to work for freestyle job. But I can't get them to work with pipeline jobs. They don't cause any errors but the environment variable won't get set either.

Anyone else played around with it?

pipelineJob('example') {
  environmentVariables {
    env('ONE', '1')
    env('TWO', '2')
    groovy('''
    def a = 1
    return [THREE: 3 * a]
    ''')
  }
  
  definition {
    cps {
      script('''
      pipeline {
        agent any
        
        stages {
          stage('Env') {
            steps {
              sh 'env'
            }
          }
        }
      }
      
      ''')
    }
  }
}

thx
