这个问题之前出现过一次，和同事讨论了2天，解决了。后来合 了一下master的分支，问题又出现了，但是忘记了解决方法。现在记录一下免得时间长了又忘记了。
问题描述：

解决办法先放在前面：
快捷键搜索com.taobao.tair.impl.mc.ShieldTairManager，仔细看，出现在两个包里，按照自己的业务，在所有子模块中根据maven help插件搜索，排除掉其中一个。
解决路程：
看到报错一大堆，前面的基本都不用管，看最后报错比较简短的那一句。
com.taobao.tair.impl.mc.ShieldTairManager was loaded by com.taobao.pandora.boot.loader.ReLaunchURLClassLoader@6da9dc6, it should be loaded by Pandora Container. Can not load this fake sdk class. please refer to xxxx（这里是文档地址，公司保密协议不好透露） for the solution
意思是说ShieldTairManager 这个类是Pandora Container容器加载的，请参考某某文档解决，
复制下来文档链接在浏览器打开，发现没有权限，阿里的权限控制是做的比较严格的，到处都限制，好吧，那就不看文档了。
按照需要Pandora Container容器加载的思路，脑海里出现各种假设，难道这个类被别的人修改过了？难道本地启动不起来了吗？难道我本地启动的不是Pandora Container容器吗？
思路错了就会把你带到无尽的深渊当中。
无意当中拷贝了com.taobao.tair.impl.mc.ShieldTairManager，快捷键在项目中搜索，发现这个类出现在两个jar包中，
按照之前本地debug段点调试，发现一个奇怪的现象，
什么？构造器中构造一个对象时你直接给我抛出一个异常？？抛出的异常和项目启动时候抛出的异常是一样的，com.taobao.tair.impl.mc.ShieldTairManager was loaded by..........
看看ShieldTairManager出现在哪个jar包中，发现出现在一个A包中和一个B包中，B包是自己的外部依赖C引进来的，是需要的，那就把A包从项目中排除吧，
好吧，搜索各个子模块，去掉A包，项目本地启动，完美解决。
小经验总结：
1.看异常看最后一个报错，最后一个一般才是错误的主要原因。注意是一般。
2.思路错了会带你到无尽的深渊，一条路走不通试试另一条路。
3.一个类出现在两个jar包中，会出现奇怪的问题，必须排除掉其中一个或者改变依赖顺序。
4.要坚韧，要有耐心。
