      Like in JENKINS-50731:

      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.

      I am not sure anymore (updated) whether or not this is really a bug: because I had already "qualifiyied" calls to 'acme.<steps>' with the script context (or so) also before switching back to using inheritance (thanks to the fix of JENKINS-45982) SpecialBuild below was basically duplicating things of Build like this:

      class SpecialBuild {

  def script
  def acme

  SpecialBuild(def script) {
    this.script = script
    this.acme = script.acme
  }

  void build() {
    acme.build() { // ! Using the 'acme.build' step from 'vars/acme.groovy'
      script.node {
        acme.skipableStage("init") { // Direct usage of 'acme.skipableStage' step worked
          script.echo "acme 'Pipeline from SCM Script'"
        }

        acme.skipableStage('checkout') { // Direct usage of 'acme.skipableStage' step worked
          acme.svnCheckout('UpdateWithCleanUpdater')
        }
      }
    }
  }
  
}

      How to reproduce?

      (I tried to include only minimal things and have not tested it after this "thinning out", so maybe there are small mistakes...)

      "Jenkinsfile"
      #!/usr/bin/env groovy

echo 'Sandbox pipeline'

@Library('acme-shared-library') _

acme.specialBuild() {
}
      Classes in shared pipeline library ('src' section)
      • 'src/Build.groovy' 
        #!/usr/bin/env groovy

class Build implements Serializable {

  def script
  def acme

  Build(def script) {
    this.script = Objects.requireNonNull(script, 'script must not be null')
    this.acme = script.acme
  }

  void build(Closure body) {
    try {
      body()
    } catch (e) {
    	acme.notifyFailing(...) // Direct access/usage of 'acme' works here

    	// While there would be no need to re-throw the exception to propagate the error (because the build result must be set
    	// to failure for email-ext anyhow before), re-throw it for e.g. script approval requests:
    	throw e
    }
  }

}
      • 'src/SpecialBuild.groovy' 
        #!/usr/bin/env groovy

class SpecialBuild extends Build {

  SpecialBuild(def script) {
    super(script)
  }

  void build() {
    super.build() { // Mind this instead of 'acme.build()' like before using inheritance
      script.node {
        script.acme.skipableStage("init") { // This works
          script.echo "acme 'Pipeline from SCM Script'"
        }

        acme.skipableStage('checkout') { // ! This does NOT work
          acme.svnCheckout('UpdateWithCleanUpdater')
        }
      }
    }
  }
  
}
      Corresponding steps in shared pipeline library ('vars' section)
      • 'vars/acme.groovy' 
        #!/usr/bin/env groovy

void svnCheckout(String workspaceUpdater = 'UpdateUpdater') {
  // ...
}

void build(Map args, Closure body) {
  // ...
  def build = new Build(this)
  build.build(body)
}

void skipableStage(String stageName, Closure body) {
  skipableStage(stageName, false, body)
}
void skipableStage(String stageName, def skipCondition, Closure body) {
  skipableStage(stageName, skipCondition, null, body)
}
void skipableStage(String stageName, Closure skipBody, Closure body) {
  skipableStage(stageName, false, skipBody, body)
}
void skipableStage(String stageName, def skipCondition, Closure skipBody, Closure body) {
  // ...
}

void specialBuild() {
  // ...
  def acmeSpecialBuild = new SpecialBuild(this)
  acmeSpecialBuild.build()
}

void notifyFailing(...) { ... }

      Current log/error

      Note that this slightly differs to what would expect as it is from the original problem (with less reduced shared library code).

Finished: FAILURE

      Workaround that works:

      • Instead of calling acme.skipableStage(...) in SpecialBuild.build() => call script.acme.skipableStage(...)
