def resolve_url(url, redirects):
  """ Resolve URL of a Maven artifact.

  prefix:path is passed as URL. prefix identifies known or custom
  repositories that can be rewritten in redirects set, passed as
  second arguments.

  A special case is supported, when prefix neither exists in
  REPO_ROOTS, no in redirects set: the url is returned as is.
  This enables plugins to pass custom maven_repository URL as is
  directly to maven_jar().

  Returns a resolved path for Maven artifact.
