      Description

      1) I created sample job (see "sample_job_config.xml" attachment) which has "PROJECT_NAME" parameter
      2) I want to run it in parallel 5 times with different "PROJECT_NAME" values. I created following script for this:

      pipeline {
          agent none
          stages {
              stage('Processing projects') {
                  steps {
                      script {
                          def projects = ['project0', 'project1', 'project2', 'project3', 'project4']
                          def projectsBuilds = [:]
      
                          def labelParameters
                          for (project in projects) {
                              //JENKINS-55426 need to save iterated variable value into intermediate variable, otherwise there will be last value from collection for all jobs
                              def currentProject = project
                              labelParameters = []
                              labelParameters.add([$class: 'LabelParameterValue', name: 'node', label: 'linux'])
                              labelParameters.add([$class: "StringParameterValue", name: "PROJECT_NAME", value: currentProject])
      
                              projectsBuilds[currentProject] = {
                                  stage(String.format('%s execution', currentProject)) {
                                      build job: 'Sample-Job', parameters: labelParameters
                                  }
                              }
                          }
      
                          parallel projectsBuilds;
                      }
                  }
              }
          }
      }
      

      3) However, when I run this script it only invokes job ONCE, not FIVE TIMES (see screen)
