I've already done that. Based on the documentation in the provided classes (like Installer) I had expected that the artifact(s) being installed would be accompanied by their metadata to the local repository (as clearly documented in org.sonatype.aether.impl.Installer and org.sonatype.aether.RepositorySystem.install()).

Unfortunately this is not the case, there is no metadata associated with the installed artifacts. Or at least no files found of maven-metadata*.xml

I went barking up the wrong tree, because the metadata installation does not happen. So I thought it was my fault (may indeed still be).

I had assumed so as well, but it just does not seem to work. My code is here [1] if you're interested.

Not much difference from what I can see.
