"Aether" and the Apache Maven resolver are supported. However the docs for this are in very bad shape, and a naive Google search is likely to point you to a lot of outdated and misleading information. https://github.com/GoogleCloudPlatform/cloud-opensource-java/tree/master/dependencies has code for that does this sort of thing. That may give you some more up to date pointers.
You will likely have to use some internal Maven classes to make this work. The "published" API is lacking in a few critical areas.
