multi-branch stage with when-branch fails with NullPointerException after jenkins restart

    • workflow-cps-plugin 2801.vf82a_b_b_e3e8a_5

      Repro steps:

      • create multi-branch pipeline with the pipeline below
      • start pipeline, wait for "input" (approval) to be pending
      • restart the Jenkins service
      • click Proceed to allow the pipeline to continue
      • the second stage fails with the error below

      Notes:

      • if you do not restart Jenkins while the input stage is pending then the pipeline will complete successfully
      • this approach worked on version 2.325
      • it started failing on 2.332.3
      • it continues to fail on 2.346.1
      • note the use of "agent none" in the approval step to avoid blocking an agent while waiting on approval, and the use of "agent any" on the subsequent step to pull the source code and perform further actions

      Pipeline:

      pipeline {
          agent none
          stages {
              stage('Approval') {
                  agent none
                  when {
                      anyOf {
                          branch 'main'
                      }
                  }
                  steps {
                      script {
                          timeout(time: 7, unit: 'DAYS') {
                              milestone()
                              input "Approve?"
                          }
                      }
                  }
              }
              stage('After Approval') {
                  agent any
                  when {
                      anyOf {
                          branch 'main'
                      }
                  }
                  steps {
                      script {
                          echo env.BRANCH_NAME
                      }
                  }
              }

          Description Original: Repro steps:
           * create multi-branch pipeline with the pipeline below
           * start pipeline, wait for "input" (approval) to be pending
           * restart the Jenkins service
           * click Proceed to allow the pipeline to continue
           * the second stage fails with the error below

          Notes:
           * if you do not restart Jenkins while the input stage is pending then the pipeline will complete successfully
           * this approach worked on version 2.325
           * it started failing on 2.332.3
           * it continues to fail on 2.346.1
           * note the use of "agent none" in the approval step to avoid blocking an agent while waiting on approval, and the use of "agent any" on the subsequent step to pull the source code and perform further actions

          Pipeline:
          {code:java}
          pipeline {
              agent none
              stages {
                  stage('Approval') {
                      agent none
                      when {
                          anyOf {
                              branch 'main'
                          }
                      }
                      steps {
                          script {
                              timeout(time: 7, unit: 'DAYS') {
                                  milestone()
                                  input "Approve?"
                              }
                          }
                      }
                  }
                  stage('After Approval') {
                      agent any
                      when {
                          anyOf {
                              branch 'main'
                          }
                      }
                      steps {
                          script {
                              echo env.BRANCH_NAME

          as a non-ideal work-around, on the stages after the approval stage, i'm using script blocks to filter by branch, instead of using `when`

           

           

          steps {
              script {
                  // branch/tag check is implemented as a script to work-around a bug in the "when" block
