Okay, I've tried creating a mod for 1.12.2 about a dozen times now, and it just doesn't seem to work. I would like somebody to point out whatever obvious mistakes I made in my mod so I attached the files.

Main.java

Reference.java

ClientProxy.java

CommonProxy.java

Sorry, I should've explained that better  My mod doesn't load when I start the client and I've checked my mcmod file so I probably screwed up somewhere in the code. Just in case, I'll attach the mcmod file, but that shouldn't stop it from loading if it is wrong.

mcmod.info

Maybe I shouldn't have switched straight from 1.7.10 to 1.12.2 modding.

How exactly do you have your project set up?

Well I don't know how to explain it, but here's the hierarchy I guess:

src>main:

 java>

  catwolf57>minecraftChocolate>

   Main.java

   proxy>

    ClientProxy.java

    CommonProxy.java

   util>

    Reference.java

 resources>

  mcmod.info

  pack.mcmeta

 

 

Hope that crappy hierarchy answers the question(especially since if it doesn't I probably look really stupid).

 

 

Oh, I downloaded the recommended forge 1.12.2 version and copy the contents of it into my mod folder. I opened the cmd window and ran gradlew setupDecompWorkspace and then gradlew eclipse in the folder. I run eclipse then select the eclipse folder in the mod folder and open it. 

This is only here because the comment glitched out and posted twice

oops

ok, but the repository might be broken because I've never done it before.

That all looks correct. I can't say why this won't work unfortunately. Please provide a Git repository of your mod to spot any potential problems.

Oh sorry I never uploaded the git repository, I spaced it out because I was finally able to fix the issue.

I have the same problem, I switched straight from 1.16.5 to 1.12.2 modding and i cant launch the program, when i was in 1.16 it launched but now is just not launching and the console is saying this :
