Vaadin Spring Boot + Bower components

Hi, I’m trying to use vaadin spring boot with the addon app-layout, but this addon uses some bower components, I just tried some examples in the my build pom, but nothing working.

I tried this example https://github.com/marcushellberg/polymer-spring-boot/blob/master/pom.xml
and https://github.com/appreciated/vaadin-app-layout/blob/master/app-layout-demo/pom.xml

When I was using this addon with guice and jetty it was working fine.

this is what is loading in my project ![chrome-inspect]
