我是靠谱客的博主迷路水池，最近开发中收集的这篇文章主要介绍将类依赖的包一起打包到jar中，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

(TaildirSource.java:236)] Unable to tail files
java.lang.NoClassDefFoundError: com/alibaba/fastjson/JSON
at MyInterceptor.intercept(MyInterceptor.java:35)
at MyInterceptor.intercept(MyInterceptor.java:70)
at org.apache.flume.interceptor.InterceptorChain.intercept(InterceptorChain.java:62)
at org.apache.flume.channel.ChannelProcessor.processEventBatch(ChannelProcessor.java:148)
at org.apache.flume.source.taildir.TaildirSource.tailFileProcess(TaildirSource.java:263)
at org.apache.flume.source.taildir.TaildirSource.process(TaildirSource.java:226)
at org.apache.flume.source.PollableSourceRunner$PollingRunner.run(PollableSourceRunner.java:133)
at java.lang.Thread.run(Thread.java:745)

运行自定义flume拦截器报错，

只有自己写的代码，没有代码中需要的依赖
