Pass a Groovy List as parameter to Build command in Jenkinsfile

Question

I want to be able to pass a List variable to the Build command in Jenkinsfile something like:

stage('test') {
  def listName = []
  build job: "/job/jobname", parameters: listName, propagate: false
}

When I try something like this I get an error:

hudson.model.PasswordParameterValue~PasswordParameterValue(name: String, value: String, description: String)}[], propagate?: boolean, quietPeriod?: int, wait?: boolean): java.lang.ClassCastException: class org.jenkinsci.plugins.workflow.support.steps.build.BuildTriggerStep.setParameters() expects java.util.List but received class java.lang.String

That error appears to be referring to other code than what is in the question. — Matthew Schuchard, Aug 30 '19 at 13:17

Was able to get through this by using below code:

stage('test') {
   def listName = []
   listName .add([$class: 'StringParameterValue', name: "${listKey}", value: "${list.value}"])
   build job: "/job/jobname", parameters: listName, propagate: false
}

You should pass Map to parameters:

stage('test') {
  def listName = [string(name: 'PARAM_NAME', value: "PARAM_VALUE")]
  build job: "/job/jobname", parameters: listName, propagate: false
}

But aren't you passing a `List` here? – Cameron Hudson Feb 20 '20 at 17:28
