F43nd1r Posted July 22, 2019 Posted July 22, 2019 I tried to register a custom Stairs Block in my mod, but it always leads to a crash: java.lang.ExceptionInInitializerError at net.minecraftforge.registries.NamespacedDefaultedWrapper$Factory.onCreate(NamespacedDefaultedWrapper.java:154) at net.minecraftforge.registries.RegistryBuilder.lambda$getCreate$2(RegistryBuilder.java:228) at net.minecraftforge.registries.ForgeRegistry.<init>(ForgeRegistry.java:127) at net.minecraftforge.registries.RegistryManager.createRegistry(RegistryManager.java:134) at net.minecraftforge.registries.RegistryBuilder.create(RegistryBuilder.java:184) at net.minecraftforge.registries.GameData.init(GameData.java:169) at net.minecraftforge.registries.GameData.<clinit>(GameData.java:153) at net.minecraft.block.Block.<clinit>(Block.java:81) at com.faendir.minecraft.hadron.generated.ModObjects0.<clinit>(ModObjects0.java:76) at com.faendir.minecraft.hadron.generated.Registry1.registerBlock(Registry1.java:35) at net.minecraftforge.eventbus.ASMEventHandler_10_Registry1_registerBlock_Register.invoke(.dynamic) at net.minecraftforge.eventbus.ASMEventHandler.invoke(ASMEventHandler.java:80) at net.minecraftforge.eventbus.EventBus.post(EventBus.java:258) at net.minecraftforge.fml.javafmlmod.FMLModContainer.fireEvent(FMLModContainer.java:106) at java.base/java.util.function.Consumer.lambda$andThen$0(Consumer.java:65) at java.base/java.util.function.Consumer.lambda$andThen$0(Consumer.java:65) at net.minecraftforge.fml.ModContainer.transitionState(ModContainer.java:112) at net.minecraftforge.fml.ModList.lambda$dispatchSynchronousEvent$4(ModList.java:110) at java.base/java.util.ArrayList.forEach(ArrayList.java:1378) at net.minecraftforge.fml.ModList.dispatchSynchronousEvent(ModList.java:110) at net.minecraftforge.fml.ModList.lambda$static$0(ModList.java:81) at net.minecraftforge.fml.LifecycleEventProvider.dispatch(LifecycleEventProvider.java:71) at net.minecraftforge.fml.ModLoader.dispatchAndHandleError(ModLoader.java:173) at net.minecraftforge.fml.ModLoader.lambda$gatherAndInitializeMods$21(ModLoader.java:165) at net.minecraftforge.registries.GameData.fireRegistryEvents(GameData.java:918) at net.minecraftforge.fml.ModLoader.gatherAndInitializeMods(ModLoader.java:165) at net.minecraftforge.fml.client.ClientModLoader.lambda$begin$2(ClientModLoader.java:68) at net.minecraftforge.fml.client.ClientModLoader.lambda$createRunnableWithCatch$5(ClientModLoader.java:84) at net.minecraftforge.fml.client.ClientModLoader.begin(ClientModLoader.java:68) at net.minecraft.client.Minecraft.init(Minecraft.java:456) at net.minecraft.client.Minecraft.run(Minecraft.java:365) at net.minecraft.client.main.Main.main(Main.java:128) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:564) at net.minecraftforge.userdev.FMLUserdevClientLaunchProvider.lambda$launchService$0(FMLUserdevClientLaunchProvider.java:55) at cpw.mods.modlauncher.LaunchServiceHandlerDecorator.launch(LaunchServiceHandlerDecorator.java:37) at cpw.mods.modlauncher.LaunchServiceHandler.launch(LaunchServiceHandler.java:50) at cpw.mods.modlauncher.LaunchServiceHandler.launch(LaunchServiceHandler.java:68) at cpw.mods.modlauncher.Launcher.run(Launcher.java:80) at cpw.mods.modlauncher.Launcher.main(Launcher.java:65) at net.minecraftforge.userdev.LaunchTesting.main(LaunchTesting.java:101) Caused by: java.lang.NullPointerException: Attempted to get vanilla wrapper for unknown registry: class net.minecraft.util.SoundEvent at org.apache.commons.lang3.Validate.notNull(Validate.java:225) at net.minecraftforge.registries.GameData.getWrapper(GameData.java:233) at net.minecraft.util.registry.Registry.forge(Registry.java:250) at net.minecraft.util.registry.Registry.<clinit>(Registry.java:77) ... 43 more I'll try to add all relevant classes here, please ask if I need to provide more information to receive help. @Mod.EventBusSubscriber( modid = "hadron", bus = Mod.EventBusSubscriber.Bus.MOD ) public class Registry1 { ... @SubscribeEvent public static void registerBlock(RegistryEvent.Register<Block> event) { event.getRegistry().register(ModObjects0.OAK_WOOD_WALL);

Am I doing something wrong? Quote
DavidM Posted July 23, 2019 Posted July 23, 2019 Do not use static initializers. Initialize your items and blocks during the appropriate registry events. Please post a GitHub repo of your mod. Quote Some tips: Spoiler Modder Support: Spoiler 1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code. 2. Always post your code. 3. Never copy and paste code. You won't learn anything from doing that. 4. Quote Programming via Eclipse's hotfixes will get you nowhere 5. Learn to use your IDE, especially the debugger. 6. Quote The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it. Support & Bug Reports: Spoiler 1. Read the EAQ before asking for help. Remember to provide the appropriate log(s). 2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.
F43nd1r Posted August 1, 2019 Author Posted August 1, 2019 The problem was actually related to gradle subprojects. I split my code into two modules, with one depending on the other. Apparently forge doesn't support this scenario. Quote
