Pipeline jobs - pass parameters upstream?

Question

TL;DR: Obviously in a Jenkins pipeline job you can easily pass parameters downstream. What I want to know is if you can pass them upstream.

Use ca

Answer 1

It should be as simple as that:

stage ('Build 3') {
        res = build job: 'job_three', parameters: [[$class: 'StringParameterValue', name: 'filename', value: "$filename"]]
        echo "$res.buildVariables.filename"
}

Assuming that in job_three you do

env.filename = "col new file name"
