Это то, что я получаю из командной строки .. и я использую окно 7.

Answer 1

Похоже, что соединение не установлено в удаленное хранилище Maven. Прокси IE может привести к этой ошибке.

Выполните следующие действия для решения этой проблемы: -

Шаг 1: Проверьте свои данные прокси-сервера на - Tools-->Internet Options-->Connections-->LAN Settings

Шаг 2: скопировать и порт прокси

Шаг 3: перейти по умолчанию локального расположения хранилища: Default: ~/.m2/repository и редактировать файл 'settings.xml'

поиска прокси-тег и заполнить детали, как

цен ниже

<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> 

По умолчанию Порт прокси: 80 (применяется в соответствии с вашими настройками)

, если вы не нашли 'settings.xml' файл на '~/.m2/repository' месте в хранилище по умолчанию затем скопировать этот файл из '~\apache-maven-3.0.5\conf' места.

Шаг 4: сохраните файл.

Шаг 5: работать в команде prompt-- mvn:archetype generate

ваша проблема должна быть решена.

Answer 2

Да у меня была такая же проблема, настройки прокси-сервера в файле setting.xml marven папки командой

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

затем снимите комментарий раздел прокси и и установить прокси-сервер, как показано ниже

<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>
