Maven - 无法使用 Maven 模板创建项目

Question

我正在尝试使用命令 propmt 中的 maven 模板创建 maven 项目。但看起来下载 jar 并且 gatting 失败了。 Maven 版本是 3.2.1。请告知为什么会这样？

C:\workspace>mvn archetype:generate -DgroupId=com.mkyong -DartifactId=CounterWebApp -DarchetypeArtifactId=maven-archetype-webapp -Dinte ractiveMode=false [INFO] Scanning for projects...

您是否正在使用代理？如果是这样，您可以在 %MAVEN_HOME%/conf/settings.xml 中检查您的代理配置

 <proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>http</protocol>
  <username></username>
  <password></password>
  <host></host>
  <port></port>
  <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
</proxy>

您似乎无法连接到 maven 存储库
