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's a simple example without loops or functions based on @Ed Randall's post:

node('docker') {
    stage('unit test') {
        parallel([
            hello: {
                echo "hello"
            },
            world: {
                echo "world"
            }
        ])
    }

    stage('build') {
        def stages = [:]

        stages["mac"] = {
            echo "build for mac"
        }
        stages["linux"] = {
            echo "build for linux"
        }

        parallel(stages)
    }
}

...which yields this:

Note that the values of the Map don't need to be stages. You can give the steps directly.
