Cannot add any web components to design

[pleku]

Steps to reproduce

1. get Spring project base from vaadin.com/start (Vaadin 14 RC1)
2. Install designer
3. switch to designer EAP channel
4. add a new design (added Java companion file)

Actual behavior

5. in designer palette all vaadin web components are disabled and "tooltip" says I'm missing required dependencies

Expected behavior

5. one can add eg. Vaadin button as a design to the project from the palette

IDE, Designer and OS version

IntelliJ IDEA 2019, Designer EAP (4.?), Windows 10

Happened to me with Vaadin 14 RC2 Spring base starter

This also happens with a Spring Boot project created by using http://start.vaadin.com. Using IntelliJ and Designer EAP 4.3.0.beta2

Same issue with plain java starter (IDEA). All components are disabled.

Also I couldn't even create new design there before I had ran mvn jetty:run once. I know it tells to run 'mvn clean package', but again, designer should secure dependencies it needs. Frontend dependency management is very volatile in npm based projects.
