Error with Maven Dependencies in PlayN project

I try learn PlayN, after creating Maven Project and adding dependency to pom.xml 

enter code here
<dependency> 
  <groupId>com.threerings</groupId> 
  <artifactId>tripleplay</artifactId>

</dependency>

I use classes from tripleplay library for menu system, such as showed in Showcase demo project. When run project as Java application all ok, but when run as html application I got errors like this

ant.bat run-html

....

It's strange that the GWT compiler would crash, rather than generating a normal error message. But it looks like you need to add the tripleplay GWT module to your GWT project.

In your game you'll have a file that's named something like:

mygame/html/src/main/java/mypackage/mygame/MyGame.gwt.xml

In that file, you need to add:

<inherits name="tripleplay.TriplePlay"/>

That will let GWT know that it can and should use the TriplePlay source code when compiling things to JavaScript.
