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

To simplify the answer of @Ed Randall here. Remember this is Jenkinsfile scripted (not declarative)

stage("Some Stage") {
    // Stuff ...
}


stage("Parallel Work Stage") {

    // Prealocate dict/map of branchstages
    def branchedStages = [:]

    // Loop through all parallel branched stage names
    for (STAGE_NAME in ["Branch_1", "Branch_2", "Branch_3"]) {

        // Define and add to stages dict/map of parallel branch stages
        branchedStages["${STAGE_NAME}"] = {
            stage("Parallel Branch Stage: ${STAGE_NAME}") {
                // Parallel stage work here
                sh "sleep 10"
            }
        }

    }

    // Execute the stages in parallel
    parallel branchedStages
}


stage("Some Other Stage") {
    // Other stuff ...
}

Please pay attention to the curly braces. This will result in the following result (with the BlueOcean Jenkins Plugin):
