collect the result from pipeline triggered downstream jobs

Hey,

I have been trying different ways to collect the result from pipeline
triggered downstream jobs without any success. Any idea how to do it?

Apprioach #1 - Mapping the build data trough Cause.UpstreamCause (as
suggested here:
https://groups.google.com/forum/#!topic/jenkinsci-dev/nNvy6YLgP58):

pipelineIntegrationJobs.each {
i -> jobs["${nirvanaMajor}.${nirvanaMinor}_${i}"] = {
build (job: "${nirvanaMajor}.${nirvanaMinor}_${i}",
parameters: [
string(name: 'branch', value: "${svnBranch}", description: 'svn repository
url'),
string(name: 'buildmajor', value: '10', description: 'release major
identifier'),
string(name: 'buildminor', value: '4', description: 'release minor
identifier'),
string(name: 'fix', value: "${env.fix}", description: 'fix level'),
string(name: 'buildnumber', value: "${env.buildNumber}", description:
'artifacts build number'),
string(name: 'revision', value: "${env.buildNumber}", description:
'checkout revision'),
string(name: 'joblabel', value: "${pipelineName}", description: "optional
job description")
], quietPeriod: 0, propagate: false, wait: true).result
def upstreamJob =
Jenkins.instance.getItem("${nirvanaMajor}.${nirvanaMinor}_${env.JOB_NAME}")
def job = Jenkins.instance.getItem("${nirvanaMajor}.${nirvanaMinor}_${i}")
job.builds.each { Run build ->
if (build.result != null) {
Cause.UpstreamCause cause = build.getCause(Cause.UpstreamCause.class)
if (cause.pointsTo(upstreamJob)) {
println("------------>" + build.number)
}
}
}
}
}

This results in a NPE:
05:34:41 Finished

[Pipeline] {
[Pipeline] echo
05:34:41 ------------------------------------
[Pipeline] echo
05:34:41 Job Status Summary:

Approach #2 - Using the .result property of the build job (as suggested in
the official documentation here:
https://jenkins.io/doc/pipeline/steps/pipeline-build-step/):

pipelineIntegrationJobs.each {
i -> jobs["${nirvanaMajor}.${nirvanaMinor}_${i}"] = {
childJob = build (job: "${nirvanaMajor}.${nirvanaMinor}_${i}",
parameters: [
string(name: 'branch', value: "${svnBranch}", description: 'svn repository
url'),
string(name: 'buildmajor', value: '10', description: 'release major
identifier'),
string(name: 'buildminor', value: '4', description: 'release minor
identifier'),
string(name: 'fix', value: "${env.fix}", description: 'fix level'),
string(name: 'buildnumber', value: "${env.buildNumber}", description:
'artifacts build number'),
string(name: 'revision', value: "${env.buildNumber}", description:
'checkout revision'),
string(name: 'joblabel', value: "${pipelineName}", description: "optional
job description")
], quietPeriod: 0, propagate: false, wait: true).result
}
childJobName = "${nirvanaMajor}.${nirvanaMinor}_${i}"
jobStateResults.put(childJobName, childJob)
}

In post section:
script {
println "------------------------------------"
println "Job Status Summary:"
jobStateResults.each{ k, v -> println "${k}:${v}" }
println "------------------------------------"
}

This yields null:

17:56:37 [10.4_test_admin_api_win] null
[Pipeline] [10.4_test_admin_api_win] }
[Pipeline] [10.4_test_admin_tool_win] echo
18:04:25 [10.4_test_admin_tool_win] null
[Pipeline] [10.4_test_admin_tool_win] }
[Pipeline] [10.4_test_cluster_tool_win] echo
18:17:44 [10.4_test_cluster_tool_win] null
[Pipeline] [10.4_test_cluster_tool_win] }
[Pipeline] [10.4_test_jms_linux] echo
18:22:33 [10.4_test_jms_linux] null
[Pipeline] [10.4_test_jms_linux] }
[Pipeline] [10.4_test_client_system_linux] echo
18:26:41 [10.4_test_client_system_linux] null
[Pipeline] [10.4_test_client_system_linux] }
[Pipeline] [10.4_test_jms_win] echo
18:39:40 [10.4_test_jms_win] null
[Pipeline] [10.4_test_jms_win] }
[Pipeline] [10.4_test_client_system_win] echo
18:47:20 [10.4_test_client_system_win
