Aggregates repository definitions by merging duplicate repositories and optionally applies mirror, proxy and
authentication settings from the supplied session.
Params:
session – The repository session during which the repositories will be accessed, must not be null.
dominantRepositories – The current list of remote repositories to merge the new definitions into, must not be null.
recessiveRepositories – The remote repositories to merge into the existing list, must not be null.
recessiveIsRaw – true if the recessive repository definitions have not yet been subjected to mirror, proxy and authentication settings, false otherwise.

RepositorySystemSession.getMirrorSelector()

Returns:
The aggregated list of remote repositories, never null./**
