Title: Message Title

Alexander Samoylov created an issue   Jenkins / JENKINS-59778 Pipeline script fails to call Java code on slave: Failed to deserialize the Callable object Issue Type: Bug Assignee: Jeff Thompson Components: pipeline, remoting Created: 2019-10-14 11:56 Environment: Jenkins server: 2.190.1 Priority: Minor Reporter: Alexander Samoylov This is a simple pipeline script on which the issue is reproduced: import jenkins.security.MasterToSlaveCallable; //import hudson.remoting.Callable; def executeJavaCodeOnNode() { def node = Jenkins.getInstance().slaves.find({it.name == env.NODE_NAME}) def hostChannel = node.getComputer().getChannel() def task = new MasterToSlaveCallable<String, IOException>() { public String call() throws IOException { return new String("-on the node-"); } }; hostChannel.call(task); } // Main node ('linux-01') { executeJavaCodeOnNode() } This simple pipeline script fails with multiple Java exceptions. I think the most relevent of them are: java.lang.IllegalArgumentException: Unable to locate class file for class WorkflowScript$1 at hudson.remoting.Which.classFileUrl(Which.java:65) at hudson.remoting.RemoteClassLoader$ClassLoaderProxy.fetch4(RemoteClassLoader.java:860) at hudson.remoting.RemoteClassLoader$ClassLoaderProxy.fetch3(RemoteClassLoader.java:889) at sun.reflect.GeneratedMethodAccessor753.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at hudson.remoting.RemoteInvocationHandler$RPCRequest.perform(RemoteInvocationHandler.java:929) at hudson.remoting.Request$2.run(Request.java:369) at hudson.remoting.InterceptingExecutorService$1.call(InterceptingExecutorService.java:72) at org.jenkinsci.remoting.CallableDecorator.call(CallableDecorator.java:19) at hudson.remoting.CallableDecoratorList$1.call(CallableDecoratorList.java:21) at jenkins.util.ContextResettingExecutorService$2.call(ContextResettingExecutorService.java:46) at jenkins.security.ImpersonatingExecutorService$2.call(ImpersonatingExecutorService.java:71) and Also: hudson.remoting.Channel$CallSiteStackTrace: Remote call to channel at hudson.remoting.Channel.attachCallSiteStackTrace(Channel.java:1743) at hudson.remoting.Request.call(Request.java:202) at hudson.remoting.RemoteInvocationHandler.invoke(RemoteInvocationHandler.java:286) at com.sun.proxy.$Proxy5.fetch3(Unknown Source) at hudson.remoting.RemoteClassLoader.findClass(RemoteClassLoader.java:209) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:348) at hudson.remoting.MultiClassLoaderSerializer$Input.resolveClass(MultiClassLoaderSerializer.java:134) at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1868) at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1751) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:2042) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1573) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:431) at hudson.remoting.UserRequest.deserialize(UserRequest.java:291) at hudson.remoting.UserRequest.perform(UserRequest.java:190) at hudson.remoting.UserRequest.perform(UserRequest.java:54) at hudson.remoting.Request$2.run(Request.java:369) at hudson.remoting.InterceptingExecutorService$1.call(InterceptingExecutorService.java:72) .... .... ....
