Included the component in my pom and now get the following at startup…
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'vaadinApplicationContextInitializer' defined in class path resource [com/vaadin/flow/spring/VaadinApplicationConfiguration.class]
: Initialization of bean failed; nested exception is java.lang.IllegalStateException: Running project in development mode with no access to folder '/Users/dgos/Development/workspace/Unilabs/vaadin/notification-menu/notification-menu'.
Build project in production mode instead, see https://vaadin.com/docs/v15/flow/production/tutorial-production-mode-basic.html
