Caused by: java.lang.ClassNotFoundException: org.apache.rocketmq.remoting.common.RemotingUtil

前言

启动报错，打包可以，启动报错；
针对这个问题 可以看下.ClassNotFoundException和NoClassDefFoundError:有啥区别先

排查

先检索pom文件，查询是否使用此jar包，并没检索到，推测是其他jar内部依赖使用
全局检索使用RemotingUtil这个类的地方，发现有个2.7.7版本（因为此包是公司内部一个包，不同于公共仓库的，所以需要本地解决），重新删除本地maven包，找同事获取他运行可以的包，重新反向安装使用，需要安装的可以参考我这篇文章
idea 反向安装jar包到仓库
