搜索得知 ZonedDateTime 的jdk 8的类， 估计也是。。 于是使用jdk8吧
E:\downloads\ff\ase-master\ase-master>set classpath=e:\java\
jdk1.8.0_20\lib

软件直接读取 JAVA_HOME ？ 我 JAVA_HOME 设置的原因？

E:\downloads\ff\ase-master\ase-master>set JAVA_HOME=E:\Java\
jdk8\

E:\downloads\ff\ase-master\ase-master>mvn

Error: JAVA_HOME is set to an invalid directory.
JAVA_HOME = "E:\Java\jdk8\ "
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

晕... 目录是确实存在的 ， 为什么说 invalid ？

我去， 最后， 只能退出cmd， 从电脑属性 - 设置环境变量了， 重新设置 JAVA_HOME 为 8 后， 问题解决！
