Hi jfernandez,
Naïve guess(es):
* Are you maybe missing this:
import com.cloudbees.groovy.cps.NonCPS
* though not sure if the annotation would/should not then lead to an
error instead already?
* Or is this a declarative pipeline and you are missing the script { … }
step based wrapping of calling your findCommitter() method (assuming that
calling it when being declared in the declarative pipeline is even allowed like
this)?
steps {
script {
findComitter()
}
}

Subject: how to avoid cps error using XmlSlurper() method in jenkins pipeline
I am using a simple test pipeline to get a username out of a xml file, I have
written a simple function using the XmlSlurper method and I have included the
@NonCPS annotation at the beginning of the function but I keep getting an
error, even though the function seems to work as it prints out in the console
the username I am trying to find but it finishes the build with failure status.
This is the pipeline:
```
import groovy.xml.*
import jenkins.model.Jenkins
@NonCPS
def findComitter(){
committer = ""
found = false
file = new
XmlSlurper().parse("C:/Users/User/.jenkins/jobs/Phoenix_pipeline/builds/288/changelog6429015253614530280.xml")
file.entry.each { entry ->
entry.changenumber.each { changenumber ->
changenumber.children().each { tag ->
if(tag.name() == "changeUser" && found != true){
committer = tag.text()
found = true
}
}
}
}
println committer
//return committer.toString()
}
pipeline {
agent any
stages {
stage('test') {
steps {
findComitter()
}
}
}
}
```
this is the output I get, as you can see the function call seems to work as it
get to the ```println commiter``` step but then I get an error and failure
build status:

I have been looking through the SO threads and all the info I got is to use the
@NonCPS annotation to use any non-serializable objects, which I have done.
