I'm not quite sure what you're asking. Are you wondering why the 
pattern I supplied is truly necessary, and why your fails?

org.codehaus.enunciate#enunciate-rt;1.10 specifies a *module*, which 
will have multiple artifacts. If you retrieve those based solely upon 
name-revision.ext, then jars containing different contents, and with 
different type will collide into the same local jarname when you retrieve.

Try "find ~/.ivy2 -name 'enunciate*.jar'" and see what you get 
(substitute the name of your cacheDir if you've changed the default). 
You'll see that the enunciate module has two jars with an artifact 
name of enunciate-rt (they differ by classifier). That's why a 
more-specific retrieve pattern is required.

Thanks,
