推荐答案
清理项目，然后再试一次。也许一个Eclipse的问题。
Clean your project and try again. Maybe a Eclipse issue.
您是否尝试过使用的另一个项目？
你确定有关错误的堆栈跟踪。也许ClassNotFound的异常是由另一个内部错误导致的。
Have you tried to use that on another project? Are you sure about the error stack trace. Maybe the ClassNotFound Exception is caused by another internal error.
