Jenkins / JENKINS-29554 job stuck when executing shell script Issue Type: Bug Assignee: Unassigned Attachments: thread_dump.txt Components: core Created: 22/Jul/15 8:27 AM Environment: windows 7 Priority: Critical Reporter: Gan Dong Hi, My job gets stuck forever when executing a trivial shell script which simply sets up the execution env: [workspace] $ sh -xe "D:\Tomcat 5.5\temp\hudson8794539940981712077.sh" Then it hangs there and never returns. When I logon to the host and run above command manually, there is no issue and the shell commands get executed and displayed correctly. Couldn't find any clue in the threaddump: "Executor #0 for master : executing testlogic-build-ant192 #268" Id=53 Group=main RUNNABLE (in native) at java.lang.ProcessImpl.waitForInterruptibly(Native Method) at java.lang.ProcessImpl.waitFor(Unknown Source) at hudson.Proc$LocalProc.join(Proc.java:319) at hudson.tasks.CommandInterpreter.join(CommandInterpreter.java:137) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:97) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:66) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:20) at hudson.model.AbstractBuild$AbstractBuildExecution.perform(AbstractBuild.java:761) at hudson.model.Build$BuildExecution.build(Build.java:203) at hudson.model.Build$BuildExecution.doRun(Build.java:160) at hudson.model.AbstractBuild$AbstractBuildExecution.run(AbstractBuild.java:536) at hudson.model.Run.execute(Run.java:1741) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:43) at hudson.model.ResourceController.execute(ResourceController.java:98) at hudson.model.Executor.run(Executor.java:374) For a full threaddump, please see the attachement. Could anyone suggest what issue this could be? Thanks in advance, Gan Dong Add Comment

Re: job stuck when executing shell script Could be an issue with the specific commands you're executing in the script. Try finding out which it is.

Re: job stuck when executing shell script

Hi Daniel, Thanks for the response. The issue persists if I replaced the script with merely one echo line: bash-3.2$ cat setenv.sh simple echo echo "This message should be displayed.." It still hangs there and output nothing. It runs fine when I log on to the host and run the same command. D:\testlogic-jenkins\jobs\testlogic-build-ant192\workspace>cat setenv.sh simple echo echo "This message should be displayed.." D:\testlogic-jenkins\jobs\testlogic-build-ant192\workspace>bash -xe setenv.sh + echo This message should be displayed.. This message should be displayed.. D:\testlogic-jenkins\jobs\testlogic-build-ant192\workspace>sh -ex setenv.sh + echo This message should be displayed.. This message should be displayed.. Note I have configured my job with following line to invoke the script: bash -ex setenv.sh It should be able to print the command it executes, but it prints nothing - seems simply hangs before entering the script. Thanks, Gan

Re: job stuck when executing shell script

Hi Daniel, Thanks for the response. The issue persists if I replaced the script with merely one echo line:

{quote} bash-3.2$ cat setenv.sh  ## simple echo

echo "This message should be displayed.." It still hangs there and output nothing. It runs fine when I log on to the host and run the same command. D:\testlogic-jenkins\jobs\testlogic-build-ant192\workspace>cat setenv.sh

## simple echo

echo "This message should be displayed.." D:\testlogic-jenkins\jobs\testlogic-build-ant192\workspace>bash -xe setenv.sh + echo This message should be displayed.. This message should be displayed.. D:\testlogic-jenkins\jobs\testlogic-build-ant192\workspace>sh -ex setenv.sh + echo This message should be displayed..

This message should be displayed.. {quote}

Note I have configured my job with following line to invoke the script: bash -ex setenv.sh It should be able to print the command it executes, but it prints nothing - seems simply hangs before entering the script. Thanks, Gan

Re: job stuck when executing shell script

Looks like I'm facing the same issue, but I can provide more details. In my case shell script hangs in the middle. So I have one shell script, which calls another shell script parent script has this line: ./tools/create_report.sh "Success" "$TEMP_FOLDER/report_template_1.html" child script (create_report.sh) has "#!/bin/bash -x" annotation and following lines in the middle JENKINS_LINKS="JENKINS_LINKS - > $JENKINS_LINKS <! -" DATE=`date "+%H:%M %d %b %Y"` oneLineMessage=`echo $message | sed "s|\n|<br>|g" | sed "s|<br><br>|<br>|g"` Console output shows: + JENKINS_LINKS='JENKINS_LINKS - > <a href="<some URL>">Console output</a> <! -' ++ date '+%H:%M %d %b %Y' and that's it - script hangs forever after date This is reproducible very rarely.

Re: job stuck when executing shell script

I'm facing the same issue. My pipeline script is very simple, I'm running this pipeline is a Unix slave(Configured via SSH). pipeline{ agent {label 'unix-slave'} stages{ stage("test"){ steps{ script { sh "java -version" } } } } }  This pipeline gets stuck at sh command and fails with the following error, ""process apparently never started in /home/user/jenkins/workspace/Test@tmp/durable-e039cc5c (running Jenkins temporarily with -Dorg.jenkinsci.plugins.durabletask.BourneShellScript.LAUNCH_DIAGNOSTICS=true might make the problem clearer)""
