      Description

      (probably/likely related to JENKINS-51166)

       

      in a scripted pipeline using a shared library "vars" .groovy file, passing "params.*" values results in an exception  

      java.lang.NullPointerException: Cannot get property (property) on null object
      

      but if I define an intermediary variable and pass that, it works

      I'm not sure how to explain it in groovy parlance, but an example should demonstrate:

      shared-test/vars/paramEcho.groovy (provided via filesystem_scm 2.1): 

      #!/usr/bin/env groovy
      
      def call(body) {
          def config = [:]
          body.resolveStrategy = Closure.DELEGATE_FIRST
          body.delegate = config
          body()
      
          node {
              echo "config=${config}"
          }
      }
      

      failing Jenkinsfile 

      #!groovy
      
      @Library('shared-test') _
      
      properties( [
          parameters([
              booleanParam(name:'truefalse', defaultValue:true, description:'boolean')
              ,string(name:'stringthing', defaultValue:'mary had a little lamb', description:'string')
          ])
      ] )
      
      paramEcho {
          booleanvalue = params.truefalse
          stringvalue = params.stringthing
      }
      

       

      result
