Brad Szabo commented on MNG-2969:
---------------------------------
The reason I have been interested in excluding/overriding a plugin dependency
stems from the issue described in MOJO-687. The short explanation is that the
xmlbeans-maven-plugin v2.0.0 has a transitive dependency (xmlbeans-jsr173-api)
which does not exist anywhere. This makes the plugin unusable without local
modification to the plugin POM. So in that case, one could argue that the
plugin writer unfortunately did not know better :( It would be nice to quickly
work around this by being able to exclude the non-existent transitive
dependency.

> Key: MNG-2969
> URL: http://jira.codehaus.org/browse/MNG-2969
> Project: Maven 2
> Issue Type: Bug
> Components: Dependencies
> Affects Versions: 2.0.6
> Reporter: Stefano Bagnara
>
> When we add a "standard" dependency we can tune its dependency list using the
> exclusions directive.
> THis is not possible with plugins.
> Let's say I add javacc-maven-plugin to my build/plugins section and the
> plugin declared in its pom:
> <dependency>
> <groupId>org.codehaus.plexus</groupId>
> <artifactId>plexus-utils</artifactId>
> <version>1.0.4</version>
> </dependency>
> And I know that this dependency is a compile dependency and I won't need it,
> how can I tune my plugin inclusion so to not download plexus-utils?
> in <pluginManagement> I can add new dependencies to plugin (WHY is this
> needed?) but I cannot exclude existing dependencies: isn't this a bug?
> I can add a new dependency to the plugin and add exclusions for this new
> dependency but I cannot add an exclusion for the top-level dependencies.
> Am I missing something?
