NoClassDefFoundError错误发生的原因

NoClassDefFoundError错误的发生，是因为Java虚拟机在编译时能找到合适的类，而在运行时不能找到合适的类导致的错误。例如在运行时我们想调用某个类的方法或者访问这个类的静态成员的时候，发现这个类不可用，此时Java虚拟机就会抛出NoClassDefFoundError错误。与ClassNotFoundException的不同在于，这个错误发生只在运行时需要加载对应的类不成功，而不是编译时发生。很多Java开发者很容易在这里把这两个错误搞混。

简单总结就是，NoClassDefFoundError发生在编译时对应的类可用，而运行时在Java的classpath路径中，对应的类不可用导致的错误。
解决上诉异常的办法

找到相应模块报错的jar包，调整范围，之前是test，结合异常发生原因，改成了Runtime。点击apply 然后OK就行了。
如果没能解决，建议去搜索NoClassDefFoundError相关帖子。
