[Mods with collective as a dependency] Unable to compile

GanerCodes opened this issue · 2 comments

Minecraft version: 1.21
Modloader: Fabric
Fabric loader version: 0.51.11

Hi, I'm having some trouble getting some of your mods compiled when they depend on collective. When I execute ./gradlew build, there are no failures and I have three folders for the three respective mod platforms [as well as the Common folder]. If I transfer the produced lib/….jar file from the relevant folder to my mods (using the public collective jar file alongside it), the game crashes during startup saying it cannot find DuckConfig classes.
If I compile collective locally as well, it is able to detect it. I am unsure why this is. I assume I am missing instructions for how to combine the libraries all together, which may fix the issue.
Crash Log:

[also, if it's of any additional encouragement once I get things running I have a pull request prepared for randommodeffects adding optional RNG dependence on number effects and effect level :)]

To do local testing you'll need to compile Collective similar to how you do the mod, or use one of the non-compiled Collective files from the maven: https://github.com/Serilum/.maven/tree/maven/com/natamus/collective-ml

This is due to how I merge the mod loaders into one jar, by splitting the common source. If you'd like to do a PR (thank you!), I'll build the mod correctly with the merging.

hey, thanks for your reply. I already ended up just making my own mod with my implementation, however feel free to copy paste anything from this into your mod. The important parts are the Statistics class and the last dozen or so lines which use the distribution to select the effects.
