[jira] Commented: (MNG-2811) issue description: 'Plugin
dependencies override maven core artifacts causing NoClassDefFoundErrors'
[ http://jira.codehaus.org/browse/MNG-2811?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_86956 ]
Kenney Westerhof commented on MNG-2811:
---------------------------------------
It looks like the dependencies brought in by the plugin (maven-model, plexus-utils) are not filtered out the plugin's classrealm.
Since the conflict resolution in 2.0.4 bugs ('nearer found' is reported even for dependencies at the same level, sometimes
causing older versions to replace newer onces), older versions of maven-model etc. could be used, but these should've
been filtered out using the artifact filters since they're core artifacts.
This normally works but maybe the downloading of plugins disrupts this.

> Key: MNG-2811
> URL: http://jira.codehaus.org/browse/MNG-2811
> Project: Maven 2
> Issue Type: Bug
> Components: Plugins and Lifecycle
> Affects Versions: 2.0.4
> Environment: OS agnostic, maven 2.0.4, jdk1.5
> Reporter: David J. M. Karlsen
> Priority: Blocker
> Attachments: 17artifactmultibulid.run1.log, 4artifact.filtered.log
>
>
> Usecase:
> wipe the local .m2 repo totally away. (rm -rf ~/.m2/repository)
> do a:
> mvn -X clean deploy site-deploy.
> Attached is the output from two different projects (one is a 4 artifact project - including the top pom, the other is a multibuild of 17 artifacts, also including top-pom).
> If I just re-run the "mvn -X clean deploy site-deploy" the builds will eventually succeed.
> I'll try to narrow down the pom's to pin down the failure with as little dependencies and plugins in action as possible - but this will take some time.
> I can be pinged at david@codehaus.org or david@davidkarlsen.com for re-running builds if needed.
> The logs are a little anonymized.
