Bug description

Subject PR #11072

Problem is demonstrated here:
https://gist.github.com/cstamas/c4ae65fb50a16fbc561ab49027ea0172

tl;dr: mvn spotless:apply stopped working with latest master

Facts:

• the plugin does not have G level metadata
• the complex heuristics did download all plugin JARs to figure out prefixes (hence was slow)
• the PR made Maven rely on metadata only

Debatable:

• is the change correct, or we need more here?
• is publishing a plugin to central without (expected) G level metadata (where prefixes are listed) ok?
