mirrors:
        # Worlds listed here have their settings mirrored in their children.
        # The first element 'world' is the main worlds name, and is the parent world.
        # subsequent elements 'world_nether' and 'world_the_end' are worlds which will use
        # the same user/groups files as the parent.
        # the element 'all_unnamed_worlds' specifies all worlds that aren't listed, and automatically mirrors them to it's parent.
        # Each child world can be configured to mirror the 'groups', 'users' or both files from its parent.
        world:
          world_nether:
          - users
          - groups
        world_the_end:    #独立配置end世界权限
          - users
          - groups
          all_unnamed_worlds:
          - users
          - groups
    #  world2:      (World2 would have it's own set of user and groups files)
    #    world3:
    #    - users    (World3 would use the users.yml from world2, but it's own groups.yml)
    #    world4:
    #    - groups   (World4 would use the groups.yml from world2, but it's own users.yml)
    #  world5:
    #    - world6   (this would cause world6 to mirror both files from world5)
