  • Maven更新慢怎么办?试试换成国内镜像

    汗一个,最近刚找到方法。以前竟然忍受那么慢的更新速度。

    解决办法是修改配置文件 apache-maven-3.3.3confsettings.xml

    我这边主要做了三个地方的修改

    1、仓库保存位置(默认是C盘),修改如下图

    2、添加镜像站点。找到 mirrors标签。修改如下图:

    3、修改默认JDK版本

    完整的文档settings.xml如下:

     23  | This is the configuration file for Maven. It can be specified at two levels:
     24  |
     25  |  1. User Level. This settings.xml file provides configuration for a single user,
     26  |                 and is normally provided in ${user.home}/.m2/settings.xml.
     27  |
     28  |                 NOTE: This location can be overridden with the CLI option:
     29  |
     30  |                 -s /path/to/user/settings.xml
     31  |
     32  |  2. Global Level. This settings.xml file provides configuration for all Maven
     33  |                 users on a machine (assuming they're all using the same Maven
     34  |                 installation). It's normally provided in
     35  |                 ${maven.home}/conf/settings.xml.
     36  |
     37  |                 NOTE: This location can be overridden with the CLI option:

     41  | The sections in this sample file are intended to give you a running start at
     42  | getting the most out of your Maven installation. Where appropriate, the default
     43  | values (values used when the setting is not specified) are provided.
