Hey, I'm new to the forge data generators and was trying to get them up and running. At the moments they aren't crashing or anything but they also don't seem to be generating any data, as far as I can tell they're set up correctly and I've tried both runClient and runData and as far as I can tell they neither loaded the models correctly into the game nor output them in any files I can see. I have no real idea what I'm doing though.

so I have my main data generator class that looks a bit like this:

@Mod.EventBusSubscriber(modid = GaiaTerrainMod.MODID, bus = Mod.EventBusSubscriber.Bus.MOD)
public class GaiaDataManager {

	@SubscribeEvent public static void gatherData(final GatherDataEvent event) {
		GaiaTerrainMod.LOGGER.info("gathering data!");
		DataGenerator generate = event.getGenerator();
		ExistingFileHelper existingFileHelper = event.getExistingFileHelper();

		generate.addProvider(new GaiaBlockStateGenerator(generate,existingFileHelper));
		generate.addProvider(new GaiaItemModelGenerator(generate, existingFileHelper));

		GaiaBlockTagGenerator blockTags = new GaiaBlockTagGenerator(generate, existingFileHelper);
		generate.addProvider(blockTags);
		generate.addProvider(new GaiaItemTagGenerator(generate, blockTags, existingFileHelper));

		generate.addProvider(new GaiaLootTableGenerator(generate));
		generate.addProvider(new GaiaRecipeGenerator(generate));
		GaiaTerrainMod.LOGGER.info("gathered data!");
	}
}

originally it didn't have the "@Mod.EventBusSubscriber(modid = GaiaTerrainM..." line at the top and instead was only invoked through a line in the GaiaTerrainMod constructor that looked like this:

public GaiaTerrainMod() {
    IEventBus registry_bus = FMLJavaModLoadingContext.get().getModEventBus();
    registry_bus.addListener(this::setup);

    MinecraftForge.EVENT_BUS.register(this);
    MinecraftForge.EVENT_BUS.register(GaiaDataManager.class);

    ModWoodTypes.init();

    ModBlocks.BLOCKS.register(registry_bus);
    ModItems.ITEMS.register(registry_bus);
    GaiaBiomeSelector.initBiomeMappings();
}

as you can see at the start and end of my gatherData function I have logs and when I hit "runData" they fired and I could see them as the last 2 things outputted by the console, however in GaiaBlockStateGenerator, the first data provider added to my data generator, I also put 2 logs at the start and end of the overriden registerStatesAndModels() function. These never fired, I assume they should after my gatherData logs fired. Not sure though,

as far as i can tell the issue should be somewhere in these files (unless it's somewhere weird), again I'm not getting any crashes or errors just a plain old, doesn't do the thing I want it to which clearly indicates I've done something dumb somewhere.

Did you remember to change all instances of examplemod to your mod id within build.gradle? There is an argument within the data run configuration that specifies the mods to generate data for. If your mod id is not specified there, then no data will be generated.

I hadn't done that actually but now I have and it's not made any difference as far as I can tell.

When you do your data run do you see "Initializing Data Gatherer for mods [examplemod]" in the logs, rather than [yourmodid]? If so, your run configurations are still wrong. Check to see if you have "--mod examplemod" in your IDE's run configs menu, and if you can't get it to update with gradle you can always change the --mod argument manually in your IDE.

haha, that made it start crashing which is progress!

oh the crash seems to be caused by the fact I'm missing a texture, is that not allowed
