> Maven dependency tree factory produces a dependency tree where duplicates and
> conflicts are omitted - or present, marked, but with no children. These
> duplicates (conflicts) are reported through the results of the query - but
> there's no indication that the artifact is actually incomplete (no subtree)
> or where the complete subtree should be found.
> An exhaustive dependency traversal is affected by that behaviour. The desired
> state would be to:
> * for a duplicated artifact, report also a copy of the subtree: exhaustive
> dependency traversal will process it
> * if a back reference appears, to an artifact reported higher in the branch,
> make a separate node instead of back reference, and leave the children empty.
> This prevent infinite loops during (simple) traversals.
> For graph algorithms an additional API ({*}project.dependency{*}) should be
> introduced, that
> * reports that a tree node is a duplicate, providing a reference to the
> 'master' copy of the subtree. The client may opt to skip it, process the
> master instead or just use the master's identification.
> * report that a tree node had a conflict (which has been resolved), and what
> the original (conflicting) artifact is. This will usually indicate a version
> clash between library dependencies, but it will be useful to see it in the
> data.
