I’ve made a JEI plugin which displays the custom recipes for my machines. It works perfectly fine whenever I launch my mod through Eclipse, but for some reason when I build it using gradlew, and then install it on another Minecraft instance, the recipe categories don’t work anymore, and I'm not sure why.
I’m using the same version for both Forge and JEI on both versions.
The plugin (and the rest of the code) can be found here. Some of it might be a bit messy: https://github.com/Exantris/TestMod/blob/master/java/exantris/testmod/jei/JeiPlugin.java
(I’ve never used github before, but hopefully it works).
Please let me know if there's any additional information you would like for me to provide.
Thanks in advance.
