C:\software\apache-maven-3.0.3\conf\settings.xml 我已在此处启用代理，如下所示：

….


<proxies>
    <!-- proxy
     | Specification for one proxy, to be used in connecting to the network.
     |-->
    <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>      
      <host>www.BT.co.uk</host>
      <port>80</port>
      <nonProxyHosts>localhost|google.com</nonProxyHosts>
    </proxy>

  </proxies>

…。

http

localhost | google.com

我现在面临的问题是什么？为什么不下载

找到解决方案：

解决方案#1:

settings.xml文件中的代理存在问题：

<host>webproxy</host>

4> 转到Maven settings.xml并输入为：

<proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>          
      <host>web-proxy.ind.abc.com</host>
      <port>8080</port>          
</proxy>

可选择的
真的
http
web-proxy.ind.abc.com
8080

5> 运行mvn：通过命令提示符安装或通过eclipse运行

=====

解决方案#3:

---

对于任何其他问题，请删除maven本地存储库并再次运行mvn:install。

显然这是代理问题。使用VPN或在setting.xml中编辑进程设置。

---

关于这个错误我查了很多。最后，我使用VPN（虚拟专用网络）禁用代理，并能够使用Maven的cemtral repository。

尝试检查位于以下目录下的settings.xml文件中的代理设置：

---

C:\Users\UserName\.m2

我刚刚将“\apache-maven-3.1.1\conf”目录下的setting.xml复制到windows机器的目录“${user.home}/.m2/”，并根据我的网络更改所需的代理设置，如下所示，它对我有效

<proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>http</protocol>
  <host>www-proxy.xxxx</host>
  <port>8080</port>
</proxy>

可选择的
真的
http
www-proxy.xxxx
8080

谢谢--

窗口首选项Maven用户设置。检查，settings.xml是否存在？如果eclipse拒绝，请从您的朋友处获取settings.xml或设置指向它的路径。

我们观察到，maven项目创建在尝试从此URL下载archtype时失败：该URL属于“https”协议

因此，上面提到的解决方案#2只有在对settings.xml稍作更改后才起作用。除了使用“http”协议，我还必须使用“https”

可选择的
真的
https
web-proxy.ind.abc.com
8080

希望它能帮助别人

注意：请确保检查以下internet设置

---

Internet Explorer>Internet选项>连接[选项卡]>局域网设置>在代理服务器下检查使用局域网代理服务器>高级>检查“所有协议使用相同的代理服务器”，然后单击确定。

在Settings.xml中的代理标记下添加以下内容对我有效

<proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>https</protocol>          
  <host>web-proxy.ind.abc.com</host>
  <port>8080</port>  
</proxy>

可选择的
真的
https
web-proxy.ind.abc.com
8080

问题很好，提供了所有相关信息。请将您的解决方案也添加为答案并接受，以便有此问题的其他人更容易找到它。对于所有仍需要大纲的人：。还请取消对代理标记的注释

<proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>http</protocol>
  <host>www-proxy.xxxx</host>
  <port>8080</port>

  <active>true</active>
  <protocol>https</protocol>          
  <host>web-proxy.ind.abc.com</host>
