从Aether解决依赖关系中的URL

Question

我正在使用以太来解决maven依赖关系。在Aether示例中关注this example之后

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 );
    }
}

这给了我一个List<Dependencies>。我如何从这些工件的依赖项中获取文件？
