My OS is windows 8.1. I tried 32bit and 64bit jdk 1.6 , 64bit jdk1.7, always this error.

What should I do to solve this problem. Thank you.

Answer 1

A NoClassDefFoundError specifies that a class was available during compile time but missing during runtime. In your case org.fusesource.jansi.internal.Kernel32 is either not available or uninitialized during runtime. Trying adding a reference of Jansi jar to your project. You can refer to this regarding how to debug a NoClassDefFoundError
