如果你的公司正在建立一个防火墙,并使用HTTP代理服务器来阻止用户直接连接到互联网。如果您使用代理,Maven将无法下载任何依赖。

为了使它工作,你必须声明在 Maven 的配置文件中设置代理服务器:settings.xml.

1. Maven配置文件

找到文件 {M2_HOME}/conf/settings.xml, 并把你的代理服务器信息配置写入。注:{M2_HOME}  => D:\software\yiibai.com\apache-maven

{M2_HOME}/conf/settings.xml
<!-- proxies
   | This is a list of proxies which can be used on this machine to connect to the network.
   | Unless otherwise specified (by system property or command-line switch), the first proxy
   | specification in this list marked as active will be used.
   |-->
  <proxies>
    <!-- proxy
     | Specification for one proxy, to be used in connecting to the network.
     |
    <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>
      <username>proxyuser</</username>
      <password>proxypass</password>
      <host>proxy.host.net</host>
      <port>80</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
    -->
  </proxies>

取消注释代理选项,填写您的代理服务器的详细信息。

<!-- proxies
   | This is a list of proxies which can be used on this machine to connect to the network.
   | Unless otherwise specified (by system property or command-line switch), the first proxy
   | specification in this list marked as active will be used.
   |-->
  <proxies>
      <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>
      <username>yiibai</username>
      <password>password</password>
      <host>proxy.yiibai.com</host>
      <port>8888</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
  </proxies>

2. 保存文件

完成后,Apache Maven 应该是能够通过代理服务器立即连接到Internet。

注意:重新启动不是必需的。Maven 只是一个命令,当你调用它,它会再次读取该文件。
