Open phaus opened this issue 13 years ago • 27 comments

I am using openjdk 6 and jenkins 1.437. The build direktly under CLI works fine for me. I am also using the xvnc plugin.

any progress on this one? We're having equal symptoms

i just replaced version 1.2.3 with version 1.2.2 and the error went away. I will give 1.2.4 another try :-).

phaus avatar Dec 17 '11 21:12 phaus

Sorry. I've been busy and will be busy this year... I'll try to check it in new year break..

ikeike443 avatar Dec 21 '11 07:12 ikeike443

The latest plugin update seems to work perfekt with play 1.2.4. So i think this issue is done.

phaus avatar Jan 16 '12 09:01 phaus

Oh, really? Thanks!

ikeike443 avatar Jan 16 '12 09:01 ikeike443

We also have this issue running jenkins 1.424.1 on ubuntu with openjdk 6 and play 1.2.4. Currently it happens on play command restart.

Thanks. Would you attach a stack trace or something info?

The play application crashes when restarted from jenkins but not if I restart it manually as our jenkins user. Could it be the OpenJDK?

michael1976 avatar Jan 25 '12 11:01 michael1976

Ok, it isn't an issue with OpenJDK. Today we tried the Sun 6 JDK but the problem still exists. I guess next we try to downgrade the plugin?

michael1976 avatar Jan 30 '12 13:01 michael1976

Is there any news on this fix?

mgonto avatar Mar 08 '12 14:03 mgonto

I'm also investigating this problem together with a colleague. I'll get back here if/when we find a solution.

jorgen99 avatar Mar 08 '12 15:03 jorgen99

Sorry for waiting. I'll check it soon, maybe in this month...

ikeike443 avatar Mar 14 '12 04:03 ikeike443

Ok, We don't get the ClassNotFoundException any more. We've done a couple of changes and to be honest, I'm not really sure which one of them made the errors go away.

First of all we added a parameter to the JAVA_OPTS in the jenkins.conf-file. We're running Ubuntu so our file is located in /etc/init/jenkins.conf

We use Jenkins to "restart" one of our play servers when we've pushed new features to our git-repo. We don't want Jenkins killing off our play process. So we tried adding the jvm-parameter below.

env JAVA_OPTS="-Dhudson.util.ProcessTreeKiller.disable=true"

We also noticed that the class com.gmail.ikeike443.PlayAutoTestBuilder used the deprecated way of launching processes. So we modified the code to use the new way with Launcher.ProcStarter. We also did some refactorings and broke the "perform"-method into smaller pieces.

The changes can be found in this repo: https://github.com/jorgen99/HudsonPluginForPlay

Try using a version of it and see if it helps you.

jorgen99 avatar Mar 21 '12 18:03 jorgen99

Thank you.

I'll merge it. But are you sure that this patch is a solution for the issue?

ikeike443 avatar Mar 23 '12 07:03 ikeike443

Honestly, I have not ever faced this problem.

I have been using this plugin with play-1.2.2, 1.2.3, 1.2.4 and with jenkins-1.450.

Does anybody face this problem still now?

Jorgen's solution may help you...

Are there any more info?

Thanks.

ikeike443 avatar Mar 23 '12 08:03 ikeike443

I will release jorgen's ver after getting more info.

ikeike443 avatar Mar 23 '12 08:03 ikeike443

Did you install from this repo by handed packaging (hudsonpluglinforplay) or from jenkins update center (play-plugin) ?

ikeike443 avatar Mar 23 '12 09:03 ikeike443

The version that we used when we were experiencing the problems was installed with the plugin-manager inside Jenkins.

jorgen99 avatar Mar 23 '12 09:03 jorgen99

Thanks.

Hmmmmm

OMG, I've just faced this problem with 0.0.13-SNAPSHOT just now!! But, when re-installing 0.0.12 from the plugin-manager, I do not faced this problem.

What is it..

ikeike443 avatar Mar 23 '12 09:03 ikeike443

Strange! So it seems like we did not solve the problem after all. I'll try and install 0.0.12 again and see if I can reproduce the problem again.

I am reading and investigating now..... http://jenkins.361315.n4.nabble.com/Not-stable-td4465894.html

Thanks Jorgen.

We're running Jenkins ver. 1.424.6, by the way.

jorgen99 avatar Mar 23 '12 10:03 jorgen99

I don't sure but maybe this problem is around loading job/config.xml...

Facing this issue on OS : win 7 64 JDK : 1.6.0_30 Tomcat : 7.0.25 Jenkins : 1.460 playframework-plugin : 0.0.12 play: 1.2.4 Code is on github : http://github.com/smougenot/DevOps_demo/tree/master/BACK_OFFICE/pe_presentation

My build launches several "Play commands" using jenkins : clean then deps and then precompile

this last operation throw the exception

Maybe there is a lead coherent with the modification of JAVA_OPTS. http://groups.google.com/group/play-framework/browse_thread/thread/69d1500c7d05300c

Addon to my former message

Running Jenkins in standalone mode does not cause this problem.

"%JAVA_HOME%\bin\java.exe" -jar jenkins.war
