Re: [cross-project-issues-dev] Build fails/success depending on the server in which it's run.


The error was included in the original mail/post. I'll paste you again:

INFO:  junit '-DX.display=:11' '--launch' 'org.eclipse.ocl.ecore.tests/launches/org.eclipse.ocl.ecore.tests (Plugin).launch' '--flatXML' '--output' '/opt/users/hudsonbuild/workspace/buckminster-mdt-ocl-core-3.1-nightly/MDT-OCL.test.results/org.eclipse.ocl.ecore.plugin.tests.xml'
Required plug-in 'org.eclipse.jdt.junit4.runtime' could not be found.
Terminating xvnc.
Archiving artifacts
The error could arise for any kind of problem in the configuration along the complex build process. I've not really investigated or tried to fix the error when running on master/fastlane, since the build has been properly working on hudson-slave1 since time ago. IMO, It looks like that some plugin is required in the target platform managed by buckminster when running our JUnits. What is perplexing is that the same build/configuration works in one server, but it doesn't work in other servers.

I don't really want to make you spend time on this if you don't have any clue, I'm happy while having my build working on hudson-slave1. It would be great running the build in other servers, though. So, if anybody else have a clue or has experienced and fixed this strange issue, please let us know it.

Best Regards,

You would have to help me understand what exactly is causing the failure, because the logfiles seem to be an endless spew of characters that make no sense to me  :)

In principle, all of the Linux Hudson machines are configured identically, except for their IP address and name.

Now that the servers activity is calmed down. I've decided to experiment with this issue again. The result of our build [1] has been the same (excepting that we don't have hudson-slave2 server :) as you have recently announced ):

- hudson-slave1: build succeed
- master: build failed
- fastlane: build failed

In principle, I don't have any problem to be tight to a specific server, specially now that we have more slots for hudson-server1 :D, however, I'm curious to know why this may be happening. Is anybody else experiencing this issue ?

I'm not sure if this is related or not, but the Master's disk had filled up yesterday with endless Hudson/Java stack trace spew.  I've cleared the log and restarted everything (yesterday) and all seems well.

Hello Folks,

With the storage problem we have had with the servers, I've discovered a weird issue building against different servers.

Our buckminster based build [1] used to be run using hudson-server1. However, I've discovered that if I run my build on a different server (hudson-slave2, fastlane and master) the build fails when trying to execute some Plugin Junit tests with the following error:

INFO:  junit '-DX.display=:12' '--launch' 'org.eclipse.ocl.ecore.tests/launches/org.eclipse.ocl.ecore.tests (Plugin).launch' '--flatXML' '--output' '/opt/users/hudsonbuild/.hudson/jobs/buckminster-mdt-ocl-core-3.1-nightly/workspace//test.results/org.eclipse.ocl.ecore.plugin.tests.xml'
Required plug-in 'org.eclipse.jdt.junit4.runtime' could not be found.

There are other tests which are executed. The difference is that "org.eclipse.ocl.ecore.tests (Plugin).launch" is a plugin junit tests launch configuration.

Before figuring out why this plugin is missed and who needs it, I'd like to ask you a couple of questions:

- Why could a build success in a server and fail in another one. Is there any kind of information available ?
- Does anybody face on this/similar issue ?
