API to find "effective-direct" dependencies
-- It was suggested [1] that I ask this question in a new thread, it might
have gotten lost in the noise --
I'm looking for existing API that will give me a MavenProject's
"effective-direct" dependencies, taking into account "grouped dependencies"
[2].
By "effective-direct" dependencies, I mean: all direct and all directly
listed in pom dependencies (recursively in pom dependencies, e.g. if pom
dependency has pom dependency)
I can get either direct-only [3] or all (direct and transitive) [4]
dependencies from MavenProject, but I don't see how I can get
effective-direct dependencies.
I see there is DepedencyNode [5] API, but I don't know if that will remain
stable with Maven 3 on the way. I was hoping someone already had this part
figured out and I could just leech off their work.
Thanks

Thanks, Ron, I'll look into that too.
My initial investigations lead me to DependencyNode:
org.apache.maven.shared.dependency.tree.DependencyNode
It needs a few other components to be instantiated:
org.apache.maven.shared.dependency.tree.DependencyTreeBuilder
org.apache.maven.project.MavenProject
org.apache.maven.artifact.repository.ArtifactRepository (local repository)
org.apache.maven.artifact.factory.ArtifactFactory
org.apache.maven.artifact.metadata.ArtifactMetadataSource
org.apache.maven.artifact.resolver.filter.ArtifactFilter
org.apache.maven.artifact.resolver.ArtifactCollector
I need to check if those remain stable between Maven 2 and 3. If I find
some answers, I'll post back.

How is this different from what Eclipse shows?
Can you use their code from the Pom editor?
