使用命令行代理创建maven项目时发生的问题

Question

我在setting.xml中添加了正确的代理。但是当我运行mvn命令创建maven项目时：

mvn archetype:generate -DgroupId=testDemo -DartifactId=demo1 -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false 

我收到以下错误。我尝试过使用不同的代理和系统，但得到相同的错误。另外当我在eclipse中创建maven项目时，得到相同的错误。 这是网络问题，还是可以通过setting.xml中的一些更改来解决。

这是一个网络问题。目前您的防火墙阻止行家回购http://repo.maven.apache.org/我猜你需要在setting.xml

更新更新代理网址，用户名和密码也异常显示Authentication Required所以我假设代理凭证都没有配置
