Spring Shell is very cool

If you are fed up with UI-oriented applications (like, say, Messus (a.k.a. Nexus) ) you can always try to embed a Spring-powered shell, so as to have a powerful scripting cli.

Just follow this example

https://docs.spring.io/spring-shell/docs/2.0.0.RELEASE/reference/htmlsingle/

and in a few clicks you have a functional shell.

BEWARE: baeldung has an example, but it's based on the old API. You will search in vain for Bootstrap class under org/springframework/shell
