maven java.net.UnknownHostExcep

Caused by: java.net.UnknownHostException: 10.10.19.4:18081/nexus at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)

场景：maven在ipv4上使用ipv6搜索host。

解决方案：
passing -Djava.net.preferIPv4Stack=true
when executing Maven since it is a Java program. For example:
mvn -e install -Djava.net.preferIPv4Stack=true

使用ipv4栈
