Answer 1

我对maven也有同样的麻烦。我通过将镜像添加到 maven 设置.xml 文件来解决这个问题

这是镜子 http://docs.codehaus.org/display/MAVENUSER/Mirrors+Repositories

和文档 http://maven.apache.org/settings.html#Mirrors

Answer 2

当 Maven 获取依赖项和父项目时，它会抛出一个Permission denied: connect错误。
我发现该问题可能与JDK 1.7和Windows 7中的已知错误有关。问题出在应用程序不完全支持 IPv6 或网络/防火墙不完全支持 IPv6 上。解决方法是在 Java 或 Maven 命令行参数中设置-Djava.net.preferIPv4Stack=true。

Answer 3

这很明显："权限被拒绝"。就是这样。您正在使用的存储库（其中一个）需要您在访问之前进行身份验证和授权。如果您真的无法访问或将您的登录名/密码（例如像这样放入您的settings.xml文件中），您应该停止使用此存储库，以便 Maven 可以向您介绍服务器:)。
