[Descriptor Element] configuration [Annotation] @component role="..." roleHint="..." [Required?] No [Notes] 
Populates the field with an instance of a Plexus component. This is like declaring a requirement in a Plexus component. The default requirement will have a role equal to the declared type of the field, and will use the default role hint. You can customise either of these by providing a role and/or roleHint parameter. e.g. @component role="org.apache.maven.artifact.ArtifactHandler" roleHint="ear"Note: This is identical to the deprecated form of parameter: @parameter expression="${component.yourpackage.YourComponentClass}".
