I'm pretty new to Vaadin and Spring but was looking for a version of the Vaadin Dashboard demo to get me started with my app. I found this but I can't get it to run in IntelliJ. It took me a while but I seem to have it building Ok. The following error is what I get trying to run the project. I've not changed any code.

Can you help me out?
