Cannot use intellij and vaadin

I’m using vaadin 8.3 + intellij 2017.3 with vaadin plugin.
I let the wizard making the job, but when I run with tomcat the test http://localhost:8080, I just get in the browser a wonderful “$END$”

Any idea ?

thanks

The Vaadin Support plugin is very old and [hasn’t been maintained in about 5 years]
(https://plugins.jetbrains.com/plugin/6727-vaadin-support); I recommend not using it. Instead, just create a new Maven project using one of the official archetypes and use that.
