How can I write pipeline script to trigger a job and parameters from property files

[Alex 2013]

  

   I have a jenkins pipeline and I want to have a post-build action which will trigger another job.

   That job is using parameters from property files. I wonder how I write this in the pipeline definition

   For example, below is trigger the job with a String parameter named 'systemname', thanks

   post {

          always {

                echo 'post build action'

                build job: 'metrics-report', parameters: [[$class: 'StringParameterValue', name: 'systemname', value: systemname]]

          }

    }
