[MNG-7619] Maven should explain why an artifact is present in local repository

[jira-importer]

Tamas Cservenak opened MNG-7619 and commented

Ability to make Maven record:

• why given artifact is present in local repository
• record reverse dep tree how this artifact got resolved

This is mostly for detecting dependency resolution anomalies, ideally best combined with -Dmaven.repo.local when you use new/empty local repo to build a project. After the build, you will end up with reverse dep trees in .tracking directories for each artifact.

To enable, pass -Dmaven.repo.local.recordReverseTree on CLI.
