使用代理后的命令行创建maven项目时出现问题

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

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

我得到以下错误。我尝试了不同的代理和系统，但得到了相同的错误。当我在eclipse中创建maven项目时，也会遇到同样的错误。 这是一个网络问题，还是可以通过在setting.xml中进行一些更改来解决

这是一个网络问题。目前，您的防火墙正在阻止maven repo

http://repo.maven.apache.org/

我想您需要在

setting.xml中更新代理URL、用户名和密码

另一个例外是显示
需要身份验证
，因此我假设未配置代理凭据
我已经在setting.xml中更新了代理url、用户名和密码。在某些系统中它工作，但在某些系统中它不工作
