[1.15.2] GatherDataEvent not firing

[Maciej916]

Hello I tryed to generate json resources but GatherDataEvent is never called and idk why because it worked before and now it's not beeing called, there is no error in console.

 

DataGenerators.class

@Mod.EventBusSubscriber(bus = Mod.EventBusSubscriber.Bus.MOD)
public class DataGenerators {

    @SubscribeEvent
    public static void gatherData(GatherDataEvent event) {
        DataGenerator generator = event.getGenerator();
        if (event.includeServer()) {
            generator.addProvider(new Recipes(generator));
            generator.addProvider(new LootTables(generator));
        }
    }
}

 

build.gradle

        data {
            workingDirectory project.file('run')

            property 'forge.logging.markers', 'SCAN,REGISTRIES,REGISTRYDUMP'
            property 'forge.logging.console.level', 'debug'

            args '--mod', 'indreb', '--all', '--output', file('src/generated/resources/')

            environment 'target', 'fmluserdevdata'

            mods {
                indreb {
                    source sourceSets.main
                }
            }
        }

This is likely because the annotation cannot find / generate an instance of your class.  
Try to use an inner static class instead. Like this:  
 

public class DataGenerators {
    
    @Mod.EventBusSubscriber(bus = Mod.EventBusSubscriber.Bus.MOD)
    public static class GatherDataSubscriber {
        @SubscribeEvent
        public static void gatherData(GatherDataEvent event) {
            DataGenerator generator = event.getGenerator();
            if (event.includeServer()) {
                generator.addProvider(new Recipes(generator));
                generator.addProvider(new LootTables(generator));
            }
        }
    }
}

Or use DeferredRegister instead.

DeferredRegister has nothing to do w/ it.

 

how do you run the data generator ?

[Busti]

They are subscribing to an event and the event is never called. That is an error that lies in the subscription, IMO and not in the code that is being executed.  
They could also place a println in their subscriber to see if the subscription worked.  
I have previously experienced relatively unpredictable behaviour when using @Mod.EventBusSubscriber on a top-level class. For some event types it works, for some it won't.  
DeferredRegister is a lot better than the annotation system IMO, it feels a lot less finicky. But it might be more complicated for new users, who do not have any FP experience. But that won't stop me from recommending it.  

Edit: I have not used GatherDataEvent or anything related to it yet. So if that's where the problem lies, I won't be able to help here. From the way the post was written it sounded like it was a subscription problem, which is why I replied.

Hi! I had the same problem. I found out that the modid I put in build.gradle wasn't updating the one in the actual run config.

So look your run config and make sure the argument is indeed your modid.

I can confirm that this also solved the problem for me! In build.gradle there's a line for specifying the modid for data generation.
