Currently, when processing a MavenProject, I'm using getDependencyArtifacts to fetch the direct (non transitive) dependencies. However, this method is marked as deprecated. So, what am I supposed to use as a replacement ? I see there's the method getDependencies, but it fetches transitive dependencies, and I don't see any way to filter direct dependencies.
Am I supposed to use RepositorySystem, and its method collectDependencies, and navigate the resulting graph, and get only the children of the root, which I guess would effectively be the direct dependencies ? Don't I have more direct, non deprecated approaches ?

This is based on a quick search, there is an existing API called Aether. Its documentation is not great.
The method in it is called: getDependencies() and it retrieves direct dependencies according to the javadoc.
There is an example on github:
public class GetDirectDependencies
{
public static void main( String[] args )
throws Exception
{
System.out.println( "------------------------------------------------------------" );
System.out.println( GetDirectDependencies.class.getSimpleName() );
RepositorySystem system = Booter.newRepositorySystem();
RepositorySystemSession session = Booter.newRepositorySystemSession( system );
Artifact artifact = new DefaultArtifact( "org.eclipse.aether:aether-impl:1.0.0.v20140518" );
ArtifactDescriptorRequest descriptorRequest = new ArtifactDescriptorRequest();
descriptorRequest.setArtifact( artifact );
descriptorRequest.setRepositories( Booter.newRepositories( system, session ) );
ArtifactDescriptorResult descriptorResult = system.readArtifactDescriptor( session, descriptorRequest );
for ( Dependency dependency : descriptorResult.getDependencies() )
{
System.out.println( dependency );
}
}
}
