Git、NPM、Maven代理或镜像加速下载

Git、NPM、Maven加速下载

Git

直接在终端命令行键入命令
代理：

git config --global https.proxy http://127.0.0.1:1080
git config --global https.proxy https://127.0.0.1:1080

端口号根据情况自行修改

取消代理：

git config --global --unset http.proxy
git config --global --unset https.proxy

npm

使用淘宝镜像加速下载

npm config set registry https://registry.npm.taobao.org
npm config set disturl https://npm.taobao.org/dist
npm config set electron_mirror https://npm.taobao.org/mirrors/electron/
npm config set sass_binary_site https://npm.taobao.org/mirrors/node-sass/
npm config set phantomjs_cdnurl https://npm.taobao.org/mirrors/phantomjs/

Maven

找到Maven的安装目录，如D:\Program Files\apache-maven-3.6.3在旗下的conf目录中找到settings.xml，如果没有新建一个
复制或者修改内容为：

 <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
                          https://maven.apache.org/xsd/settings-1.0.0.xsd">
