I have a very simple pipeline that malfunctions unexpectedly. Adding @NonCPS
decorators also does not workaround the job failure problem, so I'm mystified
as to how to write this correctly. I'm not sure if there is a coding error in
the pipeline libs, a coding error in our local lib, or a simpler means of doing
what I really need. What is really weird is that the intended operation seems
to work, but fails the job with a surprise serialization traceback! Bug or
what?
The problem is simple: discover the build number of a separate project feeder
job and use that in the current pipeline.
1) Simple pipeline job (Takes a parameter, prints it out)
Takes a String parameter PARAM1
Pipeline definition:
println PARAM1
2) Global library ("jenkins-common", defined in our Jenkins configuration)
#!/usr/bin/groovy
// Pass in "buildJob"
// If the job is a multi-branch, pass in "branch" as well
// -1 indicates that we could not determine the last successful build number
def call(body) {
// evaluate the body block, and collect configuration into the object
def config = [:]
body.resolveStrategy = Closure.DELEGATE_FIRST
body.delegate = config
body()
// See http://javadoc.jenkins-ci.org/jenkins/model/Jenkins.html
jenkins = jenkins.model.Jenkins.getInstance()
job = jenkins.getItemByFullName(config.buildJob)
def build = null
if (job instanceof org.jenkinsci.plugins.workflow.job.WorkflowJob) {
build = job.getLastSuccessfulBuild()
} else if (job instanceof
org.jenkinsci.plugins.workflow.multibranch.WorkflowMultiBranchProject) {
build = job.getBranch(config.branch).getLastSuccessfulBuild()
}
if (null != build) {
result = build.getResult()
return (result == hudson.model.Result.SUCCESS) ? build.getNumber() : -1
} else {
return -1
}
}
3) Main job (Figure out any job's last successful build number and pass it to
another job)
@Library("jenkins-common")
@NonCPS
def getBuild(def name) {
return lastSuccessfulBuildnumber {
buildJob = name
branch = "master"
}
}
int awsBuild = getBuild("/CDS/AWS Cloudtrail")
// The following will yield the same result
// def awsBuild = lastSuccessfulBuildnumber {
// buildJob = name
// branch = "master"
// }
build job: '.Test/Print parameter', propagate: false, parameters: [
[$class: 'StringParameterValue', name: 'PARAM1', value: "${awsBuild}"]
]
3b) This works just fine
int awsBuild = 123
build job: '.Test/Print parameter', propagate: false, parameters: [
[$class: 'StringParameterValue', name: 'PARAM1', value: "${awsBuild}"]
]
4) Kicking off job 3 will result in a failure. But, it will properly kick off
the "print parameter" job!
5) Console output from print parameter
Started by upstream project "Main job" build number 50
originally caused by:
Started by user xxxx
Replayed #49
[Pipeline] echo
2
[Pipeline] End of Pipeline
Finished: SUCCESS
6) Console output from main job
Started by user xxxx
Replayed #50
