Internally the way @component works is to take the role of component supplied or figure it out. With that role a lookup against the container is executed. The MavenProject is not something that is available from the container because it is not a component. So I doubt it works, unless some magic was done to just make the @Component act on MavenProject's which itself doesn't make sense. It is meant to be a parameter, and that's what it has always been.
