Hello! I have a mod (let's just call it `apimod`) that I want to have other mods depend on existing. For example, if I had a mod called `examplemod`, it would require `apimod` to be installed separately for it to work properly, similarly to how other mods can use JEI's API to do things within JEI. Assuming I have both mods fully working except for any interoperability from `examplemod` to `apimod`, how would I go about adding `apimod` into my workspace for `examplemod`, but making sure the mod needs to be installed separately when running a built version of `examplemod`? So far, my closest attempts to getting this to work have been adding a "libs" folder as a repository to `examplemod`, then adding as both `compileOnly` and `runtimeOnly` dependencies, the JAR for `apimod`. However, this seems to result in a `MethodNotFoundException` when first entering a world as `apimod` fails to run some of its own, internal logic. Thank you so much for any help!

My bad, I should have clarified before that I was using `fg.deobf`. If it helps, the crash report indicates that it can't find a method:
`java.lang.NoSuchMethodError: net.minecraft.server.MinecraftServer.func_184103_al()Lnet/minecraft/server/management/PlayerList;`

I have both mods using the same mappings (the mappings pre-Mojang, I'm forgetting what they're called off of the top of my head), and both mods report the actual method name as being getPlayerList(), rather than func_184103_al() when browsing through code in IntelliJ.

 

EDIT: If it helps, the code to `apimod` is here (it fails on running PlayerTracker.tick() ). 

 

EDIT 2: To clarify a bit, the `apimod` is being built with the usual `gradlew build`, and being loaded into `examplemod` through the line you sent in your post. The `apimod` runs perfectly fine on its own in both SP and MP, so I know it's not reaching across sides. `examplemod` also makes no calls or references to `apimod`, only `apimod` is loaded alongside `examplemod` via the build.gradle line you sent.

Latest commit from here should do the trick: https://github.com/hammy3502/survival-extras-2 .

 

I haven't tested on a built JAR, only when using the runClient task.

Sorry, just made it public, forgot to do that.

Surprisingly enough, that did the trick! Thank you so much for all the help!
