URI maps to a resource, and the resource itself is a Plexus component which can itself have a reference to the host application in order to perform its work. This may not occur in the first versions of the plugin API but a resource needs to simply become the mapping mechanism by which parameters are taken from the REST side of the application and mapped into a method call within a given Plexus component. Whether that be the core Nexus application or a component provided by a plugin.

  That should be all there is to it.

  Remove set/getMojoConfiguration(..), as it will become obsolete.

* MavenSession

  We may need to enable the context injection here, since this will be
  instantiated per-project. If we always inject the same context parameters,
