> For mojo parameters which have default values in the POM but can be overriden we should have a standard way of doing this:
>     /**
>      * Directory containing the generated JAR.
>      *
>      * @parameter expression="${outputDirectory}" default-value="${pom.build.outputDirectory}"
>      * @required
>      */
>     private File outputDirectory;
> So there is a short name which can be overriden in a POM configuration or the command line (outputDirectory), but if not specified we'll fall back to the standard recommended value in the POM. There is some inconsistencies in a lot of the plug-ins with respect to this.
