dependencies and attached artifacts

Hello,
I write maven plugin, which packages jar file along with some other files and
create new file. This new file is attached at project as attached artifact with
type "nbm-file":

projectHelper.attachArtifact( project, "nbm-file", null, nbmfile );

This is ProjectA.

Than I have some other project, ProjectB, which depends on ProjectA – either
directly or it has ProjectB in transitive dependencies. In my plugin for
ProjectB I need collect all attached artifacts of type "nbm-file" from whichever
project ProjectB has in its transitive dependencies (i. e. attached artifact of
ProjectA and may be attached artifacts of type "nbm-file" from other transitive
dependencies). What is the right way how to do this? I have some code now, but I
it looks strange to do it this way:

Set artifacts = project.getArtifacts();
Iterator it = artifacts.iterator();
while ( it.hasNext() ) {
  Artifact art = (Artifact) it.next();
  if (!"nbm-file".equals(art.getType())) {
    art = artifactFactory.createArtifact(art.getGroupId(), art.getArtifactId(),
art.getVersion(), art.getScope(), "nbm-file");
    try {
      resolver.resolve(art, remoteRepos, local);
    } catch (ArtifactResolutionException ex) {
      getLog().error( ex );
      continue;
      // unknown error
    } catch (ArtifactNotFoundException ex) {
      continue;
      //attached artifact of type "nbm-file" not found, probably some normal
"jar" dependency
    }
  }
}

Should I instead transform each Artifact to MavenProject and use
getAttachedArtifacts() method? Or should this be solved in completely different
manner?

If the attached artifacts are not explicitly listed as dependencies, then your best bet is to use the projectBuilder to materialize the MavenProject and then get the attached artifacts.
