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
Title isn't good, but it's the best I can think of. I've been working on a game for almost 17 months now, and when I just tried to add multiplayer, I came across an issue. 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...

Packing 2 bit numbers into an int.
I have an array of ints where each int represents 16 blocks,
I am attempting to set and read groups of 2 bits within the int as their own numbers, but am getting numbers I did not put in. (ex. i write a 2 in but it gives me a 3 when reading)

git question, not a java question
I have a project on git, and I use github desktop to handle commits and pushes. For some reason, every time I open a branch, including main, it acts like none of my files have been added, and that I created them (when its a team project, and these files have been there for months). Its really tripping me up and making it harder to keep up with files I'm actually supposed to be working on in my branch. Anybody know what this is?
