No entity view base class given and none found in the project.

I’ve been trying out the sample project about the PizzaShop. I executed all the different commands, but at the end when creating the web-ui in Vaadin it fails.

roo> vaadin setup --applicationPackage ~.web --baseName pizzashop --themeName pizza --useJpaContainer false
Performing vaadin setup
Theme pizza already exists
Updated SRC_MAIN_WEBAPP\WEB-INF\web.xml
roo> vaadin generate all --package ~.web.ui --visuallyComposable true
No entity view base class given and none found in the project.

Any help would be most welcome
