New Vaadin 14 app fails to run, error “Failed to determine 'node' tool.” Missing Node.js and npm tools

Question

I used the Get Started page to create a new Vaadin 14 app, after choosing the Plain Java Servlet option.

The web page successfully downloaded a .zip<

Answer 1

Almost same here. Win 10, JDK 11.0.2, node 10.16.2 installed globally

mvn results in

[ERROR] Failed to determine 'npm.cmd' tool. 
[ERROR] Please install it either:
[ERROR] - by following the https://nodejs.org/en/download/ guide to install it globally
[ERROR] - or by running the frontend-maven-plugin goal to install it in this project:
[ERROR] $ mvn com.github.eirslett:frontend-maven-plugin:1.7.6:install-node-and-npm -DnodeVersion="v10.16.0"

So... first advice to install it globally fails. second one works.
