Maven: class not found - Vaadin Server

Please Help.
As my team has to start integration project on Vaadin/Activiti/Spring Data-JPA, this issue creeps up.
Team has no knowledge of Ivy, so custom Maven POM was written. (Noo Archetype :D)
Please look into attachement for Error displayed by tomcat, and project structure.
In some of the cases, tomcat is complaining misssing raindeer.scss.

Constant Maven Class Not found for Vaadin Server.
Application is vanilla copy of Document Manager Application.

Environment: Eclipse Kepler, Win 7 64bit, Tomcat 7, Maven
