这是我从命令行获得的...我正在使用Windows 7.

Answer 1

似乎连接尚未建立到远程maven存储库。 IE代理可能导致此失败。

按照以下步骤解决此问题： -

第1步：在Tools-->Internet Options-->Connections-->LAN Settings

上查看您的代理商详细信息

第2步：复制代理主机和端口

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

搜索代理标记并填写如下所示的详细信息 -

<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）

如果您未在'settings.xml'默认存储库位置找到'~/.m2/repository'文件，请从'~\apache-maven-3.0.5\conf'位置复制此文件。

第4步：保存文件。

第5步：在命令提示符上运行 - mvn:archetype generate

你的问题应该得到解决。

Answer 2

是的我有同样的问题，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>
