Vaadin/Maven2/Eclipse Build Issue

I'm trying to run "mvn verify" or "mvn vaadin:compile" to build my project and I'm getting all sorts of errors.

Environment
- Eclipse Mars
- Maven
- Vaadin 7.5.9
- maven-vaadin-application archetype

I simply created a new Maven project in Eclipse and added a few UI components to the project and now I'm trying to build it so I can test the app in Tomcat. 

The erros are in compiling the widgetset as far as I can tell.
