Jenkins ver. 2.164.3 with OpenJDK "11.0.3+1-Debian-1bpo91"
git-client-plugin v2.7.7 and v3.0.0-beta9
Jenkins slave running OpenJDK11
Hi,
I have an automated Jenkins setup. While provisioning, I add as part of init.groovy.d an SSH key as a new SSH key as credentials to the Jenkins master (new BasicSSHUserPrivateKey(..., new BasicSSHUserPrivateKey.FileOnMasterPrivateKeySource(sshKeyPath))). Furthermore, I add a job using this credentials, and I setup Jenkins slaves automatically.
When running my job the first time (which will run on a slave), I get the following exception
java.io.NotSerializableException: com.cloudbees.jenkins.plugins.sshcredentials.impl.BasicSSHUserPrivateKey$FileOnMasterPrivateKeySource at java.base/java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1185) at java.base/java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1553) at java.base/java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1510) at java.base/java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1433) at java.base/java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1179) at java.base/java.io.ObjectOutputStream.writeArray(ObjectOutputStream.java:1379) at java.base/java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1175) at java.base/java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1553) at java.base/java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1510) at java.base/java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1433) at java.base/java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1179) at java.base/java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:349) at hudson.remoting.UserRequest._serialize(UserRequest.java:264) at hudson.remoting.UserRequest.serialize(UserRequest.java:273) Caused: java.io.IOException: Unable to serialize UserRPCRequest:org.jenkinsci.plugins.gitclient.GitClient.addCredentials[java.lang.String,com.cloudbees.plugins.credentials.common.StandardCredentials](25) at hudson.remoting.UserRequest.serialize(UserRequest.java:275) at hudson.remoting.UserRequest.<init>(UserRequest.java:101) at hudson.remoting.Channel.call(Channel.java:955) at hudson.remoting.RemoteInvocationHandler.invoke(RemoteInvocationHandler.java:283) Caused: hudson.remoting.RemotingSystemException at hudson.remoting.RemoteInvocationHandler.invoke(RemoteInvocationHandler.java:299) at com.sun.proxy.$Proxy82.addCredentials(Unknown Source) at org.jenkinsci.plugins.gitclient.RemoteGitImpl.addCredentials(RemoteGitImpl.java:200) at hudson.plugins.git.GitSCM.createClient(GitSCM.java:845) at hudson.plugins.git.GitSCM.createClient(GitSCM.java:813) at hudson.plugins.git.GitSCM.checkout(GitSCM.java:1186) at org.jenkinsci.plugins.workflow.steps.scm.SCMStep.checkout(SCMStep.java:120) at org.jenkinsci.plugins.workflow.steps.scm.SCMStep$StepExecutionImpl.run(SCMStep.java:90) at org.jenkinsci.plugins.workflow.steps.scm.SCMStep$StepExecutionImpl.run(SCMStep.java:77) at org.jenkinsci.plugins.workflow.steps.SynchronousNonBlockingStepExecution.lambda$start$0(SynchronousNonBlockingStepExecution.java:47) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:834
Reloading or restarting Jenkins solves the problem.
