Hi All!
I have been asked to update a sponge plugin that is trying to interact with a forge mod. The mod’s only purpose is to access NBT functions, but I get this error
java.lang.NoSuchMethodError: net.minecraft.nbt.NBTTagCompound.getInteger(Ljava/lang/String;)I
I’ve been talking to people on the #spongedev IRC, and from what I understand, the error comes because I am not re-obfuscating the method. This is completely understandable since I’m not building from forgegradle.
It was suggested that I build using forgegradle:
IRC Conversation
phroa> forgegradle helps
SparkVGX> forgegradle for use with compiling the plugin?
SparkVGX> Is there an orthodox way to let my sponge plugin access forge/minecraft code?
<Asherslab> why not make a forge mod instead?
SparkVGX> The owner of a server has asked me to update a sponge plugin and wants it to stay as a sponge plugin unfortunately
<Asherslab> ahhh
<Asherslab> well have fun with that xD
<Asherslab> just btw it CAN be just a server-side mod…
<Asherslab> just sponge wouldn’t load it, forge would.
SparkVGX> but I’ve yet to discern how they’ve managed to compile their sponge plugin with reobf the forge src code lol
<Asherslab> ¯_(ツ)_/¯
Deamon> you make it as you would a forge mod using forge gradle (or vanilla gradle)
However, when I asked how to do so, everyone disappeared. In my own efforts, I was unable to build just by putting my src folder in and adding the sponge dependencies.
SpongeForge Build: 1.10.2-2281-5.2.0-BETA-2597

My normal sponge build gradle file which I’ve used to correctly build other normal sponge plugins that don’t require weird interactions with forge:

My weird attempt at a forge build.gradle file that I’m trying to make build my sponge plugin, so that I can have access to forge methods:

This is the stack trace error I get when trying to build it with the above forge grade. It complains of a duplicate mcmod info file, but I have no idea why.

Here is the function I’m trying to access from the sponge plugin. The nbt handler mod itself is compiled correctly with gradlew in a proper forgegradle project, so I know it’s to do with how I’m compiling my plugin.
getInteger function
public static int getInteger(Object object, String string) {
NBTTagCompound nbt = (NBTTagCompound)object;
return nbt.getInteger(string);
}
Any assistance would be greatly appreciated. If I haven’t provided enough information, please let me know.
