Maven用到的Repositories說明：
maven-central：maven中央庫，默認從https://repo1.maven.org/maven2/拉取jar
maven-releases：私庫發(fā)行版jar
maven-snapshots：私庫快照（調(diào)試版本）jar（只需要在發(fā)布的版本號后面加上-SNAPSHOT）
maven-public：倉庫分組，把上面三個倉庫組合在一起對外提供服務灌诅，在本地maven基礎配置settings.xml中使用售担。

nexus3中央倉庫改為阿里云

如果出現(xiàn)

from/to central (http://139.155.180.170:8081/repository/maven-public/): Not authorized

檢查server對應的id和mirror的id是否一致
