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和gatting失败了。 Maven版本是3.2.1。请告知为什么会这样?

你在使用代理吗?如果是这样,您可以在%MAVEN_HOME%/ conf / settings.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
