使用Nexus搭建maven仓库，安装JDK11后启动服务提示说要安装JDK8或JDK8以上的，可我使用的JDK11就是JDK8+啊，然后改换JDK8后可以正常启动。现在最新的Nexus是无法和JDK11匹配的吗？
nexus 2

The most recent version of Java 8 available.
Java 7 is not tested and problems using Java 7 will not be addressed.

Nexus Repository Manager requires a Java 8 Runtime Environment (JRE).
所以，默认推荐用jdk8，但是11不稳定
