How can i use 'parallel' option in jenkins pipeline in the 'post' section?

问题

I looked at many pipeline examples and how to write the post build section in a pipeline script. But never got my answer i was looking for. I have 4 jobs - say Job A,B,C and D. I want job A to run first, and if successful it should trigger Job B,C,D in parallel. If Job A fails, it should trigger only Job B. Something like below:

pipeline {
    agent any

stages {
    stage('Build_1') {
        steps {
            sh '''
               Build Job A
            '''
        }
    }

post {
    failure {
        sh '''
            Build Job B
        '''
    }
    success {
         sh '''
             Build Job B,C,D in parallel
         '''
    }
}
}

I tried using 'parallel' option in post section but it gave me errors. Is there a way to build Job B,C,D in parallel, in the post 'success' section?

Thanks in advance!

回答1:

The error message is quiet clear about this:

Invalid step "parallel" used - not allowed in this context - The parallel step can only be used as the only top-level step in a stages step

The more restrictive declarative syntax does not allow the usage of parallel in thw post section at the moment.

If you don't want to switch to the scripted syntax, another option that should work: Build the jobs B,C,D in parallel in a second stage and move the the failure condition in the post section of your first stage. As a result job B,C,D will run if A is successful. If A is not successful only job B will run.

pipeline {
    agent any

    stages {
        stage('one') {
            steps {
                // run job A
            }   
            post {
                failure {
                    // run job B
                }
            }
        }
        stage('two') {
            steps {
                parallel(
                     // run job B, C, D
                )

            }
        }
    }
}
