    • Jenkins 1.609.1
      Java8
      workflow 1.9
      copy artifact 1.35.2

      use the snippet generator to create a copy artifact step using the General Build Step.

      step([$class: 'CopyArtifact', filter: '*.war', fingerprintArtifacts: true, projectName: 'war', selector: [$class: 'StatusBuildSelector', stable: false]])

      add this to a simple workflow and run it.

      result -> workflow fails with exception

      java.lang.ClassCastException: org.jenkinsci.plugins.workflow.steps.CoreStep.delegate expects interface jenkins.tasks.SimpleBuildStep but received class java.lang.String
