推荐答案

根据 Maven 文档，我们必须添加一些 settings.xml 和这里提到的设置 代理指南 .

As per maven documentation we have to add some settings.xml with setting in it mentioned here Guide to proxies .

<settings>
   <proxies>
      <proxy>
        <id>example-proxy</id>
        <active>true</active>
        <protocol>http</protocol>
        <host>proxy.example.com</host>
        <port>8080</port>
        <username>proxyuser</username>
        <password>somepassword</password>
        <nonProxyHosts>www.google.com|*.example.com</nonProxyHosts>
      </proxy>
   </proxies>
   .
   .
</settings>

另一种快速下载依赖的方法如下

Another way to do download dependencies quickly is as follows

mvn clean install -DproxySet=true -DproxyHost=myproxy.com -DproxyPort=YourPort 

第二个对我来说很好.希望上述解决方案中的至少一种对您有用，希望您的网络没有来自 maven 存储库的任何被阻止的服务器.

the second one works fine for me. Hope atleast one of above solution will work for you hoping your network doesn't have any blocked servers from maven repo.
