更新 java版本（1.8.0_66）

后不久

java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)

通过激活器创建新的Play-scala应用时，我一直收到以下错误！

我不确定原因。我尝试重新安装playframework但没有运气。我在这里错过了什么吗？

检查JAVA_HOME或java版本。如果您使用的是jre而不是JDK，则会发生这种情况。下载最新的Java并将JAVA_HOME导出到当前的java应该解决这个问题。
