IDEA maven 项目如何获取项目离线运行所需的全部依赖（ .m2格式）

背景：maven项目要将整个项目的依赖移植到某无法联网服务器进行测试，需要项目离线运行所需的全部依赖

步骤：

1. 首先需要有项目源码，解压后，使用IDEA Open Project

2. 在Settings中，配置settings.xml文件的完整路径，以及依赖文件夹的完整路径

setting.xml如果没有，可以复用下面的，随便找个位置放一下（路径不要有中文）

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
