The latest and greatest, e.g. Jenkins (core) 2.115, workflow-cps 2.47
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 hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: B.privateMethod() is applicable for argument types: () values: [] at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:58) at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:54) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:48) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:113) at org.kohsuke.groovy.sandbox.impl.Checker$1.call(Checker.java:157) at org.kohsuke.groovy.sandbox.GroovyInterceptor.onMethodCall(GroovyInterceptor.java:23) at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.SandboxInterceptor.onMethodCall(SandboxInterceptor.java:133) at org.kohsuke.groovy.sandbox.impl.Checker$1.call(Checker.java:155) at org.kohsuke.groovy.sandbox.impl.Checker.checkedCall(Checker.java:159) at com.cloudbees.groovy.cps.sandbox.SandboxInvoker.methodCall(SandboxInvoker.java:17) at A.methodThatCallsPrivateMethod(WorkflowScript:8) at WorkflowScript.run(WorkflowScript:26) at ___cps.transform___(Native Method) at com.cloudbees.groovy.cps.impl.ContinuationGroup.methodCall(ContinuationGroup.java:57) at com.cloudbees.groovy.cps.impl.FunctionCallBlock$ContinuationImpl.dispatchOrArg(FunctionCallBlock.java:109) at com.cloudbees.groovy.cps.impl.FunctionCallBlock$ContinuationImpl.fixName(FunctionCallBlock.java:77) at sun.reflect.GeneratedMethodAccessor204.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at com.cloudbees.groovy.cps.impl.ContinuationPtr$ContinuationImpl.receive(ContinuationPtr.java:72) at com.cloudbees.groovy.cps.impl.ConstantBlock.eval(ConstantBlock.java:21) at com.cloudbees.groovy.cps.Next.step(Next.java:83) at com.cloudbees.groovy.cps.Continuable$1.call(Continuable.java:174) at com.cloudbees.groovy.cps.Continuable$1.call(Continuable.java:163) at org.codehaus.groovy.runtime.GroovyCategorySupport$ThreadCategoryInfo.use(GroovyCategorySupport.java:122) at org.codehaus.groovy.runtime.GroovyCategorySupport.use(GroovyCategorySupport.java:261) at com.cloudbees.groovy.cps.Continuable.run0(Continuable.java:163) at org.jenkinsci.plugins.workflow.cps.SandboxContinuable.access$101(SandboxContinuable.java:34) at org.jenkinsci.plugins.workflow.cps.SandboxContinuable.lambda$run0$0(SandboxContinuable.java:59) at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.GroovySandbox.runInSandbox(GroovySandbox.java:108) at org.jenkinsci.plugins.workflow.cps.SandboxContinuable.run0(SandboxContinuable.java:58) at org.jenkinsci.plugins.workflow.cps.CpsThread.runNextChunk(CpsThread.java:174) at org.jenkinsci.plugins.workflow.cps.CpsThreadGroup.run(CpsThreadGroup.java:332) at org.jenkinsci.plugins.workflow.cps.CpsThreadGroup.access$200(CpsThreadGroup.java:83) at org.jenkinsci.plugins.workflow.cps.CpsThreadGroup$2.call(CpsThreadGroup.java:244) at org.jenkinsci.plugins.workflow.cps.CpsThreadGroup$2.call(CpsThreadGroup.java:232) at org.jenkinsci.plugins.workflow.cps.CpsVmExecutorService$2.call(CpsVmExecutorService.java:64) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at hudson.remoting.SingleLaneExecutorService$1.run(SingleLaneExecutorService.java:131) at jenkins.util.ContextResettingExecutorService$1.run(ContextResettingExecutorService.java:28) at jenkins.security.ImpersonatingExecutorService$1.run(ImpersonatingExecutorService.java:59) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Finished: FAILURE
Workaround that works:
- Changing visibility of A.privateMethod() from private to anything else, e.g. protected or removing the modifier.
