Unable to lock by label in a declarative pipeline script

XMLWordPrintable

      Attempting to lock a resource label in a declarative pipeline script fails with the following error:

      org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
      WorkflowScript: 7: Missing required parameter: "resource" @ line 7, column 17.
                         lock(label: 'foo') {
                         ^

      The error was generated by the following declarative pipeline script:

      pipeline {
          agent none
          stages {
              stage('Build') {
                  agent none
                  steps {
                      lock(label: 'foo') {
                          echo 'Do something here that requires unique access to the resource'
                      }
                  }
              }
          }
      }
      

      If resource is swapped in for label, the script is able to execute. Likewise if lock call is called from a non-declarative pipeline, label works fine.
