Call utility function from a utility function in a Jenkins Pipeline Shared Library

Question

I am following the example under Accessing steps . In src/org/foo/Zot.groovy I would like to call a utility function defined in eg src/org/foo/Bar.groovy . How to do that?

I tried several things without success, eg:

// src/org/foo/Zot.groovy
package org.foo;

def bar = new org.foo.Bar()

def checkOutFrom(repo) {
  bar.someFunction()
  git url: "git@github.com:jenkinsci/${repo}"
}

In this case Jenkins hangs on loading the global library. I also tried to import the file.

There have been reproduction of a similar, and probably related problem here: https://issues.jenkins-ci.org/browse/JENKINS-31484

I reproduced a similar situation using the Global CPS Library. The executor stack trace shows that the thread gets locked in InvokerInvocationException, like in the link provided.

I was able to workaround my small reproduce case by adding the @NonCPS annotation to all the called methods down the line.
