In my mod i use an external library (Json.simple). Now, in order to use the mod you need to add the Json.simple jar inside the mod folder too, but what i want is to have a single jar file that contains both the mod and the library. Is this possible? And if so how can i tell gradle to export the library too into the generated jar file?

Dind't know that. But in general is it possible to bundle any external library into the jar?

If you want to try this out, then I suggest instead of bundling it, put it into mods folder. Forge should load it too, as long as it is Jar.

I know that putting the library into the mod folder works, but this is exactly what i want to know if can be avoided. I want to know if i can put just 1 jar file into the mod folder that will load both mod and library to avoid some errors from users (they could forget about the second jar)

Use the Gradle Shadow plugin.

 

You can see how I use it to shadow one of my mod's dependencies here.

Thanks, i will look at it
