Mojo fails to read parameters fed via plugin config

[Michael Coxon <MC...@fairfaxdigital.com.au>]

Maven 2.09, Windows XP, Java 1.5
 
I have built a Mojo which extends AbstractMojo via a couple of abstract
classes. These abstracts themselves request parameters, such that the
list of declarted parameters is:
 
    /**
     * @parameter expression="${localRepository}"
     */
    protected ArtifactRepository localRepository;

    /**
     * @parameter default-value="../../tomcat/ingestor/bin"
     */
    protected String ingestorContainerBinaryDirectory;
 
    /**
     * @parameter default-value="../../tomcat/deliverer/bin"
     */
    protected String delivererContainerBinaryDirectory;
 
    /**
     * @parameter default-value="../../tomcat/production-interface/bin"
     */
    protected String productionInterfaceContainerBinaryDirectory;

    /**
     * ingestor start script.
     * @parameter
     */
    private String startCommand;
 
    /**
     * ingestor start VM args.
     * @parameter default-value="catalina.bat start"
     */
    private String ingestorEnvSettings;
 
    /**
     * proof start VM args.
     * @parameter default-value=""
     */
    private String proofDelivererEnvSettings;
 
    /**
     * public start VM args.
     * @parameter default-value=""
     */
    private String publicDelivererEnvSettings;
 
    /**
     * pi start VM args.
     * @parameter default-value=""
     */
    private String productionInterfaceEnvSettings;

The problem is that none of these parameter values are being read by the
mojo when I run mvn ubercommand:run. If I supply default values to each
of these parmeters, the default values are set (as expected) the
expression values are likewise set. but if I just have @parameter, no
values are set and the parameters values reamin null.
 
Since there seems to be little or no doco or support issues around this
I'm obviously missing something obvious. Could someone kindly point out
to me what I've missed.
 
thanks
