Serious problems with Maven

As much as I'd like to be concise, this will take a while to explain. I wanted to make simple annotation processor for my side project - http server with sort of MVC model. I added annotations @Mapping and @Mappings (@Mapping is @Repeatable) and I proceeded with creating the processor. For this I used Google's AutoService, however it wouldn't generate the files (Maybe I did something wrong?). So, I included maven-compiler-plugin in my build configuration, but it still wouldn't generate the files. I started digging deeper, running mvn clean, mvn install, mvn compile, yet it almost always results in build failure. The only time it gets to work is when I delete the plugin mentioned earlier (which means that no files are generated). It's worth mentioning that my project has a umm unique structure, and so here it is: ``` HttpServerEnv/ ├─ Application/ │ ├─ src/...

Need ideas for separating my client, server, and common code for my game

I have my world separated into modifiable chunks. These chunks have code for rendering and storing the world data inside. Both client and server need the storing part, but only the client needs rendering part. I can't think of a good way to separate them so that both client and server get their versions of common, but client h...
