这是我从命令行得到的……我正在使用 Windows 7。

Answer 1

似乎尚未建立与远程 maven 存储库的连接。 IE Proxy 可能会导致此故障。

请按照以下步骤解决此问题：-

第 1 步：检查您的代理详细信息 - Tools-->Internet Options-->Connections-->LAN Settings

第 2 步：复制您的代理主机和端口

第 3 步：转到默认本地存储库位置：Default: ~/.m2/repository 并编辑 'settings.xml' 文件

搜索代理标签并填写如下详细信息-

<proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>http</protocol>
  <username><user-name></username>
  <password><password></password>     
  <host><proxy-host></host>
  <port>80</port>          
</proxy>

默认代理端口：80（根据您的设置应用）

如果您在'~/.m2/repository' 默认存储库位置未找到'settings.xml' 文件，则从'~\apache-maven-3.0.5\conf' 位置复制此文件。

第 4 步：保存文件。

第五步：在命令提示符下运行——mvn:archetype generate

您的问题应该得到解决。

Answer 2

是的，我遇到了同样的问题，通过命令在marven文件夹的setting.xml文件中配置代理

sudo gksu gedit /usr/share/maven/conf/settngs.xml

然后取消注释代理部分并设置您的代理，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>
    <username></username>
    <password></password>
    <host>10.3.100.207</host>
    <port>8080</port>
    <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
</proxy>
