Jenkins Declarative: Trigger another pipeline and pass the stage results to current pipeline

Question

I have two declarative pipelines in Jenkins. I would like to trigger pipelineB within parameters from the stage that is running inside pipeline A and check the build/stage results of pipelineB to decide whether if pipelineA should be continue or aborted. If pipelineB build/stage results is success then pipelineA should continue with Stage C, unless it should be aborted.

       stage('A'){
            steps{
                script{
                     //Do something
        }  


        stage ('B'){
            steps {
                script {
                        // Trigger another pipeline and check result of this
                        build job: 'pipelineB', parameters: [
                        string(name: 'param1', value: "value1")
                      ]
                }
            }
        }


        stage('C'){
            steps{
                script{
                   //Do something
        }

Answer 1

Get the downstream job build result and assign to upstream job build result.

script {
  // Trigger another pipeline and check result of this
  ret = build(job: 'pipelineB', 
                  parameters: [
                      string(name: 'param1', value: "value1")
                  ],
                  propagate: true,
                  wait: true)

  echo ret.result
  currentBuild.result = ret.result
}
