如果公司基于安全因素考虑，要求使用通过安全认证的代理服务器访问因特网，这种情况夏，需要为 Maven 配置HTTP代理，才能让他正常访问外部仓库，配置代理服务器需要在~/.ms2/settings.xml 文件中，添加代理配置：

 
 

<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">
