Hi, tien There is a problem in your `dependencies` section. `dubbo` is a single package including all codes related dubbo core like `netty-all` while `dubbo-serialization-kryo` is already included in `dubbo`.
If you want to do some customizing like removing some useless support in `dubbo` you could use another way to introduce the dependencies like: dubbo-common, dubbo-cluster and etc. . Certainly it will be so complicated because there are so many packages to decide which are required to be introduced and you can see the full list in `http://repo1.maven.org/maven2/org/apache/dubbo/` <http://repo1.maven.org/maven2/org/apache/dubbo/%60>. So generally we just introduce `dubbo` instead. That's already enough. best regards, Jason > On Oct 25, 2019, at 00:31, Tien Dat PHAN <[email protected]> wrote: > > the dubbo-common library as the suggestion with the help o
