    Jenkins, Junit and Flaky Test Handler plugin

    java.io.IOException: Unable to serialize com.google.jenkins.flakyTestHandler.junit.FlakyTestResult@55c1d6e9

    I am able to start slave.jar via ssh or via jnlp. The log of the connection shows that the node is correctly started. In a project, I have 2 main parts: - a svn checkout - a shell command to start cmake + compilation. If I launch my build, it hangs. Then, I disabled the svn checkout and leave only the shell command with a "echo hello". If I start the build, it hangs with the following error message: {quote} Started by user anonymous [EnvInject] - Loading node environment variables. Building remotely on slave_linux_64 in workspace /home/crystal/jenkins/workspace/TESTLinux FATAL: command execution failed java.io.IOException: Remote call on slave_linux_64 failed at hudson.remoting.Channel.call(Channel.java:723) at hudson.Launcher$RemoteLauncher.launch(Launcher.java:862) at hudson.Launcher$ProcStarter.start(Launcher.java:353) at hudson.Launcher$ProcStarter.join(Launcher.java:360) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:91) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:60) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:20) at hudson.model.AbstractBuild$AbstractBuildExecution.perform(AbstractBuild.java:804) at hudson.model.Build$BuildExecution.build(Build.java:199) at hudson.model.Build$BuildExecution.doRun(Build.java:160) at hudson.model.AbstractBuild$AbstractBuildExecution.run(AbstractBuild.java:586) at hudson.model.Run.execute(Run.java:1603) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:247) Caused by: java.lang.NoClassDefFoundError: Could not initialize class jenkins.model.Jenkins$MasterComputer at hudson.Launcher$LocalLauncher.<init>(Launcher.java:755) at hudson.Launcher$RemoteLaunchCallable.call(Launcher.java:991) at hudson.Launcher$RemoteLaunchCallable.call(Launcher.java:965) at hudson.remoting.UserRequest.perform(UserRequest.java:118) at hudson.remoting.UserRequest.perform(UserRequest.java:48) at hudson.remoting.Request$2.run(Request.java:326) at hudson.remoting.InterceptingExecutorService$1.call(InterceptingExecutorService.java:72) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at hudson.remoting.Engine$1$1.run(Engine.java:63) at java.lang.Thread.run(Thread.java:724) Build step 'Execute shell' marked build as failure Finished: FAILURE {quote} When I looked at the jenkins directory I configured on the slave, all the required jar are present, the workspace directory is present and the build directory is correctly created by the jenkins master.
