I'm developing for 1.21.1 with Neoforge and NeoGradle, this is what I added to build.gradle:
repositories {
maven { url = "https://maven.ithundxr.dev/snapshots" } // Registrate
}
dependencies {
jarJar(implementation("com.tterrag.registrate:Registrate:MC1.21-1.3.0+62"))
}The minimum reproduction example:
package dev.theblckbird.rustedcomputer;
import com.mojang.logging.LogUtils;
import net.neoforged.bus.api.IEventBus;
import net.neoforged.fml.common.Mod;
import com.tterrag.registrate.Registrate;
import net.minecraft.world.level.block.Block;
import org.slf4j.Logger;
@Mod(RustedComputer.MODID)
public class RustedComputer {
// Mod constants
public static final String MODID = "rustedcomputer";
public static final Logger LOGGER = LogUtils.getLogger();
public static final Registrate REGISTRATE = Registrate.create(MODID);
// Block registry object (deferred registration)
public static final Registrate.RegistryEntry<Block> COMPUTER =
REGISTRATE.block("computer", Block::new).register();
public RustedComputer(IEventBus eventBus) {
LOGGER.info("Rusted Computers loaded with Java");
REGISTRATE.registerEventListeners(eventBus);
}
}It works when using the Create wrapped Registrate instance.
I also haven't been the only one with this problem.
Other people have been reporting this on the Discord as well.
