我安装了play框架，并使用hello-play-java模板创建了一个应用程序。当我编译时，它有一个错误:

我的操作系统是Windows 8.1。我尝试了32位和64位jdk 1.6，64位jdk1.7，总是出现此错误。
我应该怎么做才能解决这个问题。谢谢。
最佳答案
NoClassDefFoundError指定一个类在编译时可用，但在运行时丢失。在您的情况下，org.fusesource.jansi.internal.Kernel32在运行时不可用或未初始化。尝试在项目中添加对Jansi jar的引用。您可以参考有关how to debug a NoClassDefFoundError的信息
