Hi Robert, thank you for the pointer.

Alas, the information doesn't quite solve my problems -- but maybe I'm
just being obtuse.
Let's say I want to built (and resolve) the test-scoped classpath of
org.apache.maven.shared:maven-artifact-transfer:0.9.1. All I have is
this coordinate.
What I do:
DefaultDependableCoordinate coord = new DefaultDependableCoordinate();
coord.setGroupId("org.apache.maven.shared");
coord.setGroupId("maven-artifact-transfer");
coord.setVersion("0.9.1");
dependencyResolver.resolveDependencies(
session.getProjectBuildingRequest(), coord, null);
This gives the following list of artifacts (sorted, to allow for better
comparison):
> commons-codec:commons-codec:jar:1.6
> commons-io:commons-io:jar:2.5
> org.apache.maven.shared:maven-artifact-transfer:jar:0.9.1
> org.apache.maven.shared:maven-common-artifact-filters:jar:3.0.1

This differs quite a bit from what "mvn dependency:list" outputs when
run on a SVN checkout of the maven-artifact-transfer project:
> commons-codec:commons-codec:jar:1.6:compile
> commons-io:commons-io:jar:2.5:compile
> junit:junit:jar:4.11:test
> org.apache.maven.shared:maven-common-artifact-filters:jar:3.0.1:compile
> org.apache.maven.shared:maven-shared-utils:jar:3.1.0:compile
> org.apache.maven:maven-aether-provider:jar:3.0:runtime
> org.apache.maven:maven-artifact:jar:3.0:compile

The list returned by resolveDependencies contains
maven-artifact-transfer (fine), but lacks *some* test-scoped
dependencies (like junit:junit:4.11), while others like
org.sonatype.aether:aether-impl:1.7 are included. However, a lot of
provided-scoped dependency (org.eclipse.aether) are missing, but some
are present (org.sonatype.aether).
Can you explain to me what's going on here? I feel like I am missing an
important conceptual bit.
In a similar vein, can you enlighten me what the "type" of a
DependableCoordinate is? In particular, how does it differ from the
extension or packaging?
Best wishes,
Andreas
