Cannot get property 'stages' on null object

XMLWordPrintable

      I have the following simple pipeline:

      @Library("yooture@test")
import org.foo.Zot

pipeline {
    agent any
    stages {
        stage('Example') {
            steps {
                echo 'Hello World'
            }
        }
    }
    post {
        always {
            echo 'I will always say Hello again!'
        }
    }
}

      I have the same pipeline in two separate repos in a branch called `develop` (copy/paste).

      In the repo called 'dummy' the job runs fine and the output is like this:

      As you can see from the commit hashes, the exact same version of the shared library is used: 3ca0c91267dcdad0ca87753530d6ccc72052de6d (test)

      The shared library (branch test) has only one file: src/org/foo/Zot.groovy - but its not even used within the pipeline script.

      package org.foo;

def echo(msg) {
  echo "-> ${msg}"
}

      This is as far as I was able to break down the issue, but now I'm absolutely lost and have no further ideas on how to debug this issue.
