Fresh Vaadin 8.1 app "multimodule" app fails to build

Question

When creating a new Vaadin 8.1.0 app named bogus using the archetype vaadin-archetype-application-multimodule, the build fails in IntelliJ 2017.2 when running Maven Projects panel > bogus-ui > Plugins > jetty > jetty:run

I get these error messages on console.

Using Java 8 Update 144 on macOS Sierra 10.12.5 with IntelliJ Ultimate edition 2017.2.

The linked Question, Maven: How to use jetty:run in a multi-module Maven project, without needing to install, is not a duplicate of this Question. That one asks about one module (the Web Module) picking up on changes made in other modules and causing a rebuild rather than retrieving built items from local repository. I am asking how to run the app in the first place, long before needing to trigger re-builds.

Answer 1

Lifecycle > install on root/parent module

Maven needs to find dependencies before running.

You need to run 'mvn install' on root (parent) project or on your backend module (and other project that backend depends on).
