AFAIK, Aether (deliberately?) doesn't offer this functionality.

That being said, when I come across tasks like this, I often search for
a Maven plugin that needs to do something similar. In this case,
build-helper:remove-project-artifact [1] and
dependency:purge-local-repository [2] come to mind. Their use of Aether
or its predecessor has probably seen more real-world testing than your
code will anytime soon, so chances are that they don't delete an
artifact only half-way, making a mess of the repository's metadata.

Hope this helps.

Andreas
