      Thanks to the fix of JENKINS-45982 I dared to continue with one of my original approaches using inheritance in shared Jenkins pipeline library classes, but stumbled over this problem.

      Re-producer "Jenkinsfile":

      #!/usr/bin/env groovy

class A {
  def script
  A(script) { this.script = script }
  def methodThatCallsPrivateMethod() {
    script.echo "In A.methodThatCallsPrivateMethod()"
    privateMethod()
  }
  private def privateMethod() {
    script.echo "In A.privateMethod()"
  }
}

class B extends A {
  B(script) { super(script) }
}

node {

  stage('A') {
    new A(this).methodThatCallsPrivateMethod()
  }

  stage('B') {
    new B(this).methodThatCallsPrivateMethod() // ! This will subsequently fail the pipeline
  }

}

      Current log/error:

      [Pipeline] {
[Pipeline] stage
[Pipeline] { (A)
[Pipeline] echo
In A.methodThatCallsPrivateMethod()
[Pipeline] echo
In A.privateMethod()
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (B)
[Pipeline] echo
In A.methodThatCallsPrivateMethod()
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline

      Workaround that works:

      • Changing visibility of A.privateMethod() from private to anything else, e.g. protected or removing the modifier.
