Maven依赖冲突无法解决

maven项目可以正常启动,但一种包jar包重复!!我尝试了各种方法,删掉仓库,排除依赖,利用maven helpe工具,都没有解决掉这个问题,每次启动还是会报,这让拥有强迫症的我十分难受,哪位仙人帮助解决一下!!十分感谢

我遇到过这种情况。
处理办法是：
1.把代码提交到自己分支上，然后建一个新文件夹重新拉这个代码
2.新建本地maven仓库，上面的代码用最新的代码仓库，重新maven reimport。这一步可能会花时间，但是会解决问题。

包重复， 你可以在pom.xml排除掉某个包。

这个可能是你的pom.xml里面有重复的依赖，具体有两种，比如说里面又两个相同的依赖A,或者以一个依赖B,这个依赖B其实是包含依赖A的，如果依赖A和依赖B同时存在就会导致重复，可以再依赖B上面加上排除标签，将B里面的A依赖进行排除掉

是不是依赖搭配错误了(某些依赖版本高，某些依赖版本低)
我当前依赖中也有用到netty-all这个包，不过用的版本和你的不一样
