Spotless can format <java | markdown | license headers | anything> using <gradle | maven | anything>.
Ideally, a code formatter can do more than just find formatting errors - it should fix them as well. Such a formatter is really just a Function<String, String>, which returns a formatted version of its potentially unformatted input.
It's easy to build such a function, but there are some gotchas and lots of integration work (newlines, character encodings, idempotency, and build-system integration). Spotless tackles those for you so you can focus on just a simple Function<String, String> which can compose with any of the other formatters and build tools in Spotless' arsenal.
