• mirrors may be arranged a plurality of mirror, each mirror has id, name, url, mirrorOf properties. 

• id uniquely identifies a mirror 

• name seemingly not much use, the equivalent of a library is the official description url address 

• mirrorOf represents a mirror image of alternative locations, for example, represents a central place on the central official

The above configuration <mirrorOf> * </ mirrorOf> * in the meaning (according to id mirrorOf and repository of) matches all library (repository), this means that if you need a jar, he would go to download the jar from a mirror address . No matter how many you configure the library, even if the address is not the same these libraries will still be accessible from the mirror address.
