Maven -无法使用maven模板创建项目

Question

我试图使用命令propmt中的maven模板创建maven项目。但是看起来好像下载了jar，而G占有失败了。Maven版本为3.2.1。请告诉我为什么会发生这种事？

你在和代理合作吗？如果是这样，您可以在%MAVEN_HOME%/conf/setings.xml中检查代理配置。

 <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。
