How to use maven shade plugin with spring boot 2.2.x?

Question

I am following the example provided in the answer: Spring Boot With Maven Shade Plugin - Controllers not mapped (404 Error)

But when loading the application I get:

Guess something is missing.

It looks like this:

Anyone got it working?

A solution to make not-so-fat jars (meaning no unnecessary classes) with traditional spring boot plugin is also welcome.
