Re: [aether-users] Collecting list of transitive dependencies *and* nece

Hi again,

for the benefits of others, here's my findings so far (problem still
unsolved):

I used the GetDependencyHierarchy as starting point of my odyssee
through Aether. So far I have found out the following:

- The solution to my problem *cannot* reside on the Aether side, as
Aether has no concept of "parent". The ArtifactDescriptor returned by
RepositorySystem.readArtifactDescriptor(..) just has dependencies but no
parent which Aether could make use during a subsequent
RepositorySystem.collectDependencies. Hence, a custom
DependencyCollector won't help.

- Maven's DefaultArtifactReader relies on a ModelBuilder. If I could get
a custum implementation to return a ModelBuildingResult with an
effective model listing the parents as dependencies I might be done.

- Maybe wrapping DefaultModelBuilder.build(..) and changing the
ModelBuildingResult's effective model on the fly so that the parent is
also listed as a dependency does the trick. Will try this out.

Any hints on how else to proceed are greatly appreciated, however.

Andreas
