Posted March 12, 20196 yr I want do prevent some inter-mod recipes to show up when their respective mod is missing, so I created this json-file (assets/moaroresreforged/recipes/_factories.json): { "conditions": { "spartanshields_installed": "moaroresreforged.compatibility.TestConditionFactory" } } And this class: package main.java.moaroresreforged.compatibility; import java.util.function.BooleanSupplier; import com.google.gson.JsonObject; import net.minecraftforge.common.crafting.IConditionFactory; import net.minecraftforge.common.crafting.JsonContext; import net.minecraftforge.fml.common.Loader; public class TestConditionFactory implements IConditionFactory { @Override public BooleanSupplier parse(JsonContext context, JsonObject json) { return () -> Loader.isModLoaded("spartanshields"); } } ... and it crashes terribly upon loading. I've tried adding "main.java" or variations of it to the class path without avail. The corresponding crash log: Spoiler ---- Minecraft Crash Report ---- // I feel sad now :( Time: 3/12/19 7:32 PM Description: Initializing game com.google.gson.JsonSyntaxException: Could not find IConditionFactory: moaroresreforged.compatibility.TestConditionFactory at net.minecraftforge.common.crafting.CraftingHelper.getClassInstance(CraftingHelper.java:597) at net.minecraftforge.common.crafting.CraftingHelper.loadFactories(CraftingHelper.java:581) at net.minecraftforge.common.crafting.CraftingHelper.loadFactories(CraftingHelper.java:650) at java.util.ArrayList.forEach(ArrayList.java:1249) at net.minecraftforge.common.crafting.CraftingHelper.loadRecipes(CraftingHelper.java:619) at net.minecraftforge.fml.common.Loader.initializeMods(Loader.java:742) at net.minecraftforge.fml.client.FMLClientHandler.finishMinecraftLoading(FMLClientHandler.java:336) at net.minecraft.client.Minecraft.init(Minecraft.java:581) at net.minecraft.client.Minecraft.run(Minecraft.java:421) at net.minecraft.client.main.Main.main(Main.java:118) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at net.minecraftforge.gradle.GradleStartCommon.launch(GradleStartCommon.java:97) at GradleStart.main(GradleStart.java:25) Caused by: java.lang.ClassNotFoundException: moaroresreforged.compatibility.TestConditionFactory at net.minecraft.launchwrapper.LaunchClassLoader.findClass(LaunchClassLoader.java:191) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at net.minecraftforge.common.crafting.CraftingHelper.getClassInstance(CraftingHelper.java:590) ... 21 more Caused by: java.lang.NullPointerException A detailed walkthrough of the error, its code path and all known details is as follows: --------------------------------------------------------------------------------------- -- Head -- Thread: Client thread Stacktrace: at net.minecraftforge.common.crafting.CraftingHelper.getClassInstance(CraftingHelper.java:597) at net.minecraftforge.common.crafting.CraftingHelper.loadFactories(CraftingHelper.java:581) at net.minecraftforge.common.crafting.CraftingHelper.loadFactories(CraftingHelper.java:650) at java.util.ArrayList.forEach(ArrayList.java:1249) at net.minecraftforge.common.crafting.CraftingHelper.loadRecipes(CraftingHelper.java:619) at net.minecraftforge.fml.common.Loader.initializeMods(Loader.java:742) at net.minecraftforge.fml.client.FMLClientHandler.finishMinecraftLoading(FMLClientHandler.java:336) at net.minecraft.client.Minecraft.init(Minecraft.java:581) -- Initialization -- Details: Stacktrace: at net.minecraft.client.Minecraft.run(Minecraft.java:421) at net.minecraft.client.main.Main.main(Main.java:118) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at net.minecraftforge.gradle.GradleStartCommon.launch(GradleStartCommon.java:97) at GradleStart.main(GradleStart.java:25) -- System Details -- Details: Minecraft Version: 1.12.2 Operating System: Windows 7 (amd64) version 6.1 Java Version: 1.8.0_91, Oracle Corporation Java VM Version: Java HotSpot(TM) 64-Bit Server VM (mixed mode), Oracle Corporation Memory: 776442920 bytes (740 MB) / 1497890816 bytes (1428 MB) up to 7609516032 bytes (7257 MB) JVM Flags: 0 total;

March 12, 20196 yr At the least, you're going to need the fully qualified package name in your json. You left off the "main.java." part. I know you said you already tried that, but perhaps when you did, either it still wasn't fully correct, or maybe a different exception was thrown. Try it again and see what the crash log says. If that doesn't fix the problem fully, then you might check out Draco's example: https://github.com/Draco18s/ReasonableRealism/blob/1.12.1/src/main/resources/assets/hardlib/recipes/_factories.json Perhaps Forge needs this to be a static class, too.
March 12, 20196 yr Your package name should not contain “main.java” About Me Spoiler My Discord - Cadiboo#8887 My Website - Cadiboo.github.io My Mods - Cadiboo.github.io/projects My Tutorials - Cadiboo.github.io/tutorials Versions below 1.14.4 are no longer supported on this forum. Use the latest version to receive support. When asking support remember to include all relevant log files (logs are found in .minecraft/logs/), code if applicable and screenshots if possible. Only download mods from trusted sites like CurseForge (minecraft.curseforge.com). A list of bad sites can be found here, with more information available at stopmodreposts.org Edit your own signature at www.minecraftforge.net/forum/settings/signature/ (Make sure to check its compatibility with the Dark Theme)
