Description

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.
