IDEA使用maven 下载jar包速度慢

IDEA使用maven下载jar包速度慢

1、使用maven会从国外的网站进行下载，所以速度会格外的慢，需要修改setting文件。
在项目右键—>Maven—>选择“open settings.xml”，如果没有 “open settings.xml”，则选择“create settings.xml”。
2、把下面内容复制到setting.xml中，重启IDEA，maven下载将使用国内阿里云的镜像，下载速度会明显加快。

          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.
