Marking upstream Jenkins/Hudson as failed if downstream job fails

Question

I am using Parameterized Trigger Plugin to trigger a downstream build.

How do I specify that my upstream job should fail if the downstream fails? The upstream job is

Answer 1

this code will mark the upstream build unstable/failed based on downstream job status.

def failRecursivelyUsingCauses(cause) {

        def projectName = cause.upstreamProject
        def number = cause.upstreamBuild
        upstreamJob = hudson.model.Hudson.instance.getItem(projectName)
        if(upstreamJob) {
             upbuild = upstreamJob.getBuildByNumber(number)
