Are you aware of -Xdiag:resolver?

No, I wasn't aware of that option. Nice. It presents roughly the same
info in a more procedural form.

...OTOH the quasi-graphical tree display (the idea is stolen from "mvn
dependency:tree" command) has some additional useful info such as "uses
of a service that was not satisfied" and in my opinion better visualizes
a global view of why all resolved modules are pulled-in. The procedural
"evaluation" of resolving and the final list of resolved modules is
useful too. If you like this display:
