故障排除： http://repo.maven.apache.org/maven2在浏览器中确定。
您知道NetBeans为什么重置连接吗？
UPDATE（7/21）： 尽管以上http://repo.maven.apache.org/maven2在浏览器中有效， http://repo.maven.apache.org/maven2/velocity/失败！别人还好吗？ 我尝试在手机上成功打出这个VELOCITY地址。 因此，这告诉我NetBeans可能不是问题，而是我的网络设置有问题。 我当前的网络设置为ProxyServer = OFF和AutomaticallyDetectSettings = ON。 另外，网络设置被设置为DHCP自动获取IP地址。 我已打开防火墙日志记录，以查看Defender是否阻止了任何内容。
UPDATE（7 / 21-B）： 现在，在浏览器中将HTTP切换为HTTPS会导致在浏览器中成功打开https://repo.maven.apache.org/maven2/velocity/。 因此，看来NetBeans没有使用HTTPS。
任何想法表示赞赏。
