Once the ClassRealm has been populated and all Plexus components have been discovered a lookup can be performed to retrieve the primary plugin component. Currently the component would need to be looked up and then the BasicComponentConfigurator would need to configure the component with a given Plexus configuration. We will discuss later how we would retrieve the Plexus configuration required for a given plugin.
