I was following this tutorial series and got to the point for ConfiguredFeatures or specifically in layman's terms: Ore Gen.

The issue is that the code shown in the tutorial is specific to the 1.19.2 (and below) and that some classes / constants are not available in the new update. I have seen the 1.19.3 Blogpost, and, if I understood it correctly, then the OreGen is now implemented with JSON files exclusively (as implied by the FabricDynamicRegistryProvider/DataGeneratorEntrypoint-examples in the blog).

I have checked the Wiki, which sadly isn't updated to 1.19.3 yet.
If there'll be a Wiki Update before this issue is answered, I'll close this with a link to the Wiki Page.

Given two

• net.minecraft.block.Block's (say: XOre and XDeepslateOre)
• net.minecraft.registry.RegistryKey<net.minecraft.block.Block>
• net.minecraft.util.Identifier

(choose one, whichever is more convenient) could someone provide a minimal example of the required DataGen class for the OreGen (ideally with the init-call in DataGeneratorEntrypoint#onInitializeDataGenerator).

A link to a mod, which already implements the OreGen in 1.19.3 would also work.

Thank you very much in advance.

Perhaps this would help to understand where I'm stuck, as of my understanding, you can generate stuctures, including ores with JSON Files.

I expected this to happen in a similar fashion as I would do with Block Tags (I use Kotlin btw):

package a.b.c.datagen.tag

import net.fabricmc.fabric.api.datagen.v1.FabricDataOutput
import net.fabricmc.fabric.api.datagen.v1.provider.FabricTagProvider.BlockTagProvider
import net.minecraft.registry.Registries
import net.minecraft.registry.RegistryWrapper
import net.minecraft.registry.tag.BlockTags
import a.b.c.registry.ModBlocks
import java.util.concurrent.CompletableFuture
import java.util.stream.Stream

class CustomBlockTagProvider(output: FabricDataOutput):
    BlockTagProvider(output, CompletableFuture.completedFuture(
        RegistryWrapper.WrapperLookup.of(Stream.of(Registries.BLOCK.tagCreatingWrapper))
    )) {

    override fun configure(arg: RegistryWrapper.WrapperLookup) {
        this.getOrCreateTagBuilder(BlockTags.LOGS)
            .setReplace(false)
            .add(ModBlocks.EXAMPLE_LOG)

        this.getOrCreateTagBuilder(BlockTags.LOGS_THAT_BURN)
            .setReplace(false)
            .add(ModBlocks.EXAMPLE_LOG)
    }
}

(the above works as I expect, it generated the proper tag-json's)

So, I tried:

@file:Suppress("UnstableApiUsage")

package a.b.c.datagen.feature.ore

import net.fabricmc.fabric.api.datagen.v1.FabricDataOutput
import net.fabricmc.fabric.api.datagen.v1.provider.FabricDynamicRegistryProvider
import net.minecraft.registry.Registries
import net.minecraft.registry.RegistryWrapper
import java.util.concurrent.CompletableFuture
import java.util.stream.Stream

class OreFeatureProvider(output: FabricDataOutput):
    FabricDynamicRegistryProvider(output, CompletableFuture.completedFuture(
        RegistryWrapper.WrapperLookup.of(Stream.of(Registries.FEATURE.tagCreatingWrapper))
    )) {
    override fun getName(): String {
        return "Features for minecraft:ore"
    }

    override fun configure(registries: RegistryWrapper.WrapperLookup, entries: Entries) {
        // TODO: Add ore features
    }
}

which fails with java.lang.IllegalStateException: Registry minecraft:dimension_type not found.

It seems that I have misunderstood something, so I hope for a clarification.
