In order to really achieve this, we need mojo configurations (which are
  provided both in terms of static expressions that are just looked up, and
  in terms of user-provided configuration from properties or the POM).
  If these mojos are to be first-class components, the configuration from these
  various sources must be consolidated and injected using the container.

  Currently, mojo configuration is done externally to the container, in the

          <name>proxies</name>
          <version>1.0.0+</version>
          <description>
            Configuration for different proxy profiles. Multiple proxy profiles
            might come in handy for anyone working from a notebook or other
            mobile platform, to enable easy switching of entire proxy
            configurations by simply specifying the profile id, again either from

    boolean required() default false;

 - those that are used locally by the user like <developerConnection/>

* User configuration

 User configuration which is utilized site wide are controlled with the ${user.home}/.m2/maven.properties.

 User configuration which is utilized at the project level are controlled with the
 ${project.home}/maven.properties file.

Plugin configuration

 The configuration of plugins is of the same form as the maven {{{plugin-descriptors}plugin descriptors}}
