Running Vaadin Flow beverage-starter-flow with standalone jetty does not work

Launching beverage-starter-flow with mvn jetty:run then it works just fine. But if download same version of Jetty (9.4.11.v20180605) and launch it through IntelliJ IDEA then I get the following error.

How to fix this? Should skeleton-starter-flow work with standalone Jetty?

here was an exception while trying to navigate to '' with the exception message 'Unable to create an instance of 'com.vaadin.starter.beveragebuddy.ui.views.reviewslist.ReviewsList'. The constructor threw an exception.'
java.lang.IllegalArgumentException: Unable to create an instance of 'com.vaadin.starter.beveragebuddy.ui.views.reviewslist.ReviewsList'. The constructor threw an exception.

Solution

Running Jetty or Tomcat from IntelliJ did not copy frontend folder from webapp sources to target/beveragebuddy-1.0-SNAPSHOT/frontend/. Running mvn package fixed this.
