maven的settting.xml的镜像地址配置

<!-- mirrors

  | This is a list of mirrors to be used in downloading artifacts from remote repositories.

  |

  | It works like this: a POM may declare a repository to use in resolving certain artifacts.

  | However, this repository may have problems with heavy traffic at times, so people have mirrored

  | it to several places.

  |

  | That repository definition will have a unique id, so we can create a mirror reference for that

  | repository, to be used as an alternate download site. The mirror site will be the preferred

  | server for that repository.

  |-->

  <mirrors>

    <!-- mirror

    | Specifies a repository mirror site to use instead of a given repository. The repository that

    | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used

    | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
