eclipse下的maven项目可以正常运行 打包成war包后放tomcat下不能运行

eclipse下的maven项目可以正常运行 打包成war包后放tomcat下不能运行
而且项目本身跟服务器上（对方开放的项目）大小差了一半 服务器上的项目war包邮45MB
而我使用 maven install 打包后的项目只有23MB

测试放在本地的tomcat上报

严重: Catalina.stop:

检查后发现 war包大小不同的原因是因为lib里面的jar包数量不同
然后把服务器上的lib文件夹直接复制到要上传的新项目上 在服务器上却报下面这样的错误

请问我这个到底是什么原因 maven 正确 的打包形式应该是怎样的
