So I wanted to integrate LLibrary into my mod, so I added this to my build.gradle:

 

dependencies {
  	 
		deobfCompile "net.ilexiconn:llibrary:1.7.19-1.12.2"
		deobfCompile "net.ilexiconn:llibrary-core:1.0.11-1.12.2"

}

This worked fine. I'm using Forge 1.12.2-14.23.5.2816, which LLibrary asks for (well not exactly 2816, but 2771 or higher)

However, when I launch the game, the game crashes with this error:

java.lang.NoSuchMethodError: net.minecraft.util.ResourceLocation.getNamespace()Ljava/lang/String;

I checked ResourceLocation to see if the Method exists, and sure enough, it doesn't. I tried up- and downgrading forge to various versions, but nothing seems to work. 

What am I missing here?

Do you have the deobfuscated version of the mods you want to use as libaries in your Build Path?

I mean like proper deobf's versions .. i have seen that causing errors after compiling the mod and running it & while compiling

Yes, I think I do

Anyone have an idea?

Figured it out, needed to include

compile "net.ilexiconn:llibrary:1.7.9-1.12.2:dev"

instead of 

deobfCompile "net.ilexiconn:llibrary:1.7.19-1.12.2"
