Our current workaround is to do something like:

try {
    bat "do stuff"
}
finally {
    CpsThread.current().head.get().addAction(new LabelAction("name of step"))
}

ssutherland, I'm looking for this same functionality, and I was keen to try your workaround, but I don't know where to get CpsThread from?

CpsThread is a class in one of the pipeline plugins. You'll need to add an import for it in your script

import org.jenkinsci.plugins.workflow.cps.CpsThread

Excellent, thanks

See JENKINS-37324. Do not use the CpsThread hack! Use stage to wrap your step in a labeled block.

jglick I don't believe it's supported within parallel steps?

You can put stage wherever you want (except when using Declarative). What a particular visualization plugin in its current implementation will or will not render is another matter. Pipeline Steps will show it.

Is there a separate bug for Blue Ocean not being able to visualize this, then?

node() {
    stage('Run Everything') {
        parallel firstBranch: {
            stage('Get Current Working Directory') {
                sh(script: 'pwd')
            }        
        }, secondBranch: {
            stage('Test') {
                println 'Second Branch Test'
            }        
        }
    }
}

Yes there is. I do not have time to look it up unfortunately.

Looks like I wanted JENKINS-38442
