You are missing key jar files. I would make sure you’ve correctly done an Install/Update (Look at Eclipse Preferences)
using the vaadin link: Vaadin Update Site http://vaadin.com/eclipse/

You can see how to setup Eclipse for Vaadin at this link:
https://vaadin.com/book/-/page/getting-started.environment.html#getting-started.environment.eclipse
