> MOJO-393 is about letting the user define an alternate configuration element, thus changing the way the webstart plugin works.
> For that the idea was to make the mojo field an interface, provide a default implementation in the plugin and let the user use plexus to instanciate a new implemenation.
> so for most users we would have:
> <configuration>
> <bla>
> </bla>
> </configuration>
> and for some:
> <configuration>
> <bla implementation="com....bla">
> </bla>
> </configuration>
> Unfortunately, today I am forced to specify the implementation in both cases. There's no way to inform the plugin to use the default implementation.
> The plugin.xml contains:
> <parameter>
> <name>bla</name>
> <type>...BlaInterface</type> <!-- that will fail -->
> ...
> </parameter>
> I tried to use
> /**@parameter implementation="...BlaImplementation"*/
> BlaInterface bla;
> but that fails as well.
> Marking critical because it doesn't allow me add new features to the plugin without breaking the config.xml.
