java程序报错NoSuchMethodError

在eclipse中用maven启动程序时，一切正常。使用maven打包编译好的程序，执行会报错，NoSuchMethodError，详细信息如下：

1.首先对比了打包前和打包后的两个程序，基本一致，特别比对了方法所在的引用程序包，以及程序包的版本号，甚至反编译查看内容，完全一致。

2.怀疑在打包时的问题，于是使用开发环境本地打包，保证基础环境一致，打包出来的结果依然会报错，而打包之前是正常的。

3.但程序不会平白无故报错，查看源码，引用，都是正常的，查找所有的ObjectWriter发现了问题，在版本中出现了两个ObjectWriter类，属于不同的包，其中一个是老版本中为了方便，迁移了完整路径代码，后一个是引用了程序包。删掉老版本的包，问题解决！
