Scripted jenkinsfile parallel stage

Question

I am attempting to write a scripted Jenkinsfile using the groovy DSL which will have parallel steps within a set of stages.

Here is my jenkinsfile:

n         


        

Answer 1

Here is an example from their docs:

Parallel execution

The example in the section above runs tests across two different platforms in a linear series. In practice, if the make check execution takes 30 minutes to complete, the "Test" stage would now take 60 minutes to complete!

Fortunately, Pipeline has built-in functionality for executing portions of Scripted Pipeline in parallel, implemented in the aptly named parallel step.

Refactoring the example above to use the parallel step:

// Jenkinsfile (Scripted Pipeline)


stage('Build') {
    /* .. snip .. */
}

stage('Test') {
    parallel linux: {
        node('linux') {
            checkout scm
            try {
                unstash 'app'
                sh 'make check'
            }
            finally {
                junit '**/target/*.xml'
            }
        }
    },
    windows: {
        node('windows') {
            /* .. snip .. */
        }
    }
}
