[19:02:58 ERROR] [gss]: [ACF] Caused by: java.lang.NoSuchMethodError: net.minecraft.item.ItemStack.getTagCompound()Lnet/minecraft/nbt/NBTTagCompound;

I get this error. why?

I use these settings for mapping for GradleForge

minecraft {
version = “1.11.2”
mappings = “stable_32”
}

and gradle setupDecompWorkspace/gradle clean build

is this how im supposed to do it or is reobfuscation different?

Output from gradle clean build

This mapping ‘stable_32’ was designed for MC 1.11! Use at your own peril.

Post at least your build.gradl
Btw you don’t need to run setupDecompWorkspace every time, just run gradle build

I found that gradleforge does not allow kotlin by default

topic done thx

It’s not kotlin. Forgegradle doesn’t work with that shadow plugin, it won’t obfuscate the sources

7

yep, add this to your build.gradle

reobf {
    shadowJar{}
}
tasks.build.dependsOn reobfShadowJar
