>                 Key: MNG-396
>                 URL: http://jira.codehaus.org/browse/MNG-396
>             Project: Maven 2
>          Issue Type: Improvement
>          Components: Plugins and Lifecycle
>            Reporter: Brett Porter
>            Priority: Minor
>
> currently, all plugins inherit everything in the Maven classloader hierachy, and we must
filter those out so they end up with those versions.
> We should minimise this, by separating the classloaders:
> boot - classworlds
>  |
>  v
> core - plexus
>  |
>  v
> shared - anything that is passed from Maven's core to plugins (Eg project, plugin api,
report api, ...)
>  |  
>  +-> individual plugin classloader
>  |
>  +-> Maven internal classloader - add wagon, etc.
> This allows invididual plugins to use newer or incompatible versions of JARs that Maven
itself uses.
