dubbo-registry-nacos模块需要禁止dubbo-registry-api和dubbo-common传递

[AlbumenJ]

这个是使用了 fatjar 模式后出现的重复 class 情况，后面需要考虑忽略对 fatjar 的检测

[zhaoyunxing92]

设置optional是不是就可以了

[AlbumenJ]

这个是整体打包的问题，只要用了 fatjar，所有类都会多一份，所以除非全部都变成 optional 不然没法处理

[JemyXiao]

so, this question has a solution?

[JemyXiao]

i try a solution method, you can add dependency, @zhaoyunxing92
<groupId>org.apache.dubbo</groupId> <artifactId>dubbo-common</artifactId> ${dubbo.version}

真球服了，自己引入都能jar包冲突

注册中心还能不引入？
