[1.12.2] Json recipe condition: Could not find IConditionFactory


HariboTer

Recommended Posts

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:

There is probably some embarassingly trivial mistake hiding somewhere around there, but I'm totally not seeing it and clueless at the moment about what else to do. A hint as to what I'm doing wrong here would be very welcome ?

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.

Your package name should not contain “main.java”

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

    • I had a similar issue to what you do above. Given this is an old post, you've probably sorted this now In my case, I had Java (JDK) 22 installed. After uninstalling that and installing 17.0.11 (having both installed gives the same error), then running the startserver.bat worked for me. I managed to get to the EULA section and then start my server correctly- I hope it helps anyone else who may have this issue!
    • Make a test with another Launcher like MultiMC, AT Launcher or Technic Launcher
    • I opened up Minecraft today for the first time in a month and whenever I try and play forge I get an error 1 message. I restarted my computer, tried reinstalling both Minecraft and Forge and have updated all of my drivers. Nothing seems to work so I'm stumped. I have absolutely no mods installed ATM so I have no idea what could be causing the problem. I hope yall are able to help.   DebugLog:   [19May2024 20:33:51.600] [main/INFO] [cpw.mods.modlauncher.Launcher/MODLAUNCHER]: ModLauncher running: args [--username, dmoy18, --version, 1.20.1-forge-47.2.0, --gameDir, C:\Users\dmoyf\AppData\Roaming\.minecraft, --assetsDir, C:\Users\dmoyf\AppData\Roaming\.minecraft\assets, --assetIndex, 5, --uuid, c083972cd92d4dd2894beb25b82ebe82, --accessToken, ????????, --clientId, MDljMzIwMjYtOTJiNS00YWUxLTk1M2EtN2ExMGExZWM0MDAw, --xuid, 2535417310772497, --userType, msa, --versionType, release, --quickPlayPath, C:\Users\dmoyf\AppData\Roaming\.minecraft\quickPlay\java\1716168829421.json, --launchTarget, forgeclient, --fml.forgeVersion, 47.2.0, --fml.mcVersion, 1.20.1, --fml.forgeGroup, net.minecraftforge, --fml.mcpVersion, 20230612.114412] [19May2024 20:33:51.604] [main/INFO] [cpw.mods.modlauncher.Launcher/MODLAUNCHER]: ModLauncher 10.0.9+10.0.9+main.dcd20f30 starting: java version 17.0.8 by Microsoft; OS Windows 11 arch amd64 version 10.0 [19May2024 20:33:51.634] [main/DEBUG] [cpw.mods.modlauncher.LaunchServiceHandler/MODLAUNCHER]: Found launch services [fmlclientdev,forgeclient,minecraft,forgegametestserverdev,fmlserveruserdev,fmlclient,fmldatauserdev,forgeserverdev,forgeserveruserdev,forgeclientdev,forgeclientuserdev,forgeserver,forgedatadev,fmlserver,fmlclientuserdev,fmlserverdev,forgedatauserdev,testharness,forgegametestserveruserdev] [19May2024 20:33:51.653] [main/DEBUG] [cpw.mods.modlauncher.NameMappingServiceHandler/MODLAUNCHER]: Found naming services : [srgtomcp] [19May2024 20:33:51.668] [main/DEBUG] [cpw.mods.modlauncher.LaunchPluginHandler/MODLAUNCHER]: Found launch plugins: [mixin,eventbus,slf4jfixer,object_holder_definalize,runtime_enum_extender,capability_token_subclass,accesstransformer,runtimedistcleaner] [19May2024 20:33:51.681] [main/DEBUG] [cpw.mods.modlauncher.TransformationServicesHandler/MODLAUNCHER]: Discovering transformation services [19May2024 20:33:51.688] [main/DEBUG] [net.minecraftforge.fml.loading.FMLPaths/CORE]: Path GAMEDIR is C:\Users\dmoyf\AppData\Roaming\.minecraft [19May2024 20:33:51.689] [main/DEBUG] [net.minecraftforge.fml.loading.FMLPaths/CORE]: Path MODSDIR is C:\Users\dmoyf\AppData\Roaming\.minecraft\mods [19May2024 20:33:51.689] [main/DEBUG] [net.minecraftforge.fml.loading.FMLPaths/CORE]: Path CONFIGDIR is C:\Users\dmoyf\AppData\Roaming\.minecraft\config [19May2024 20:33:51.689] [main/DEBUG] [net.minecraftforge.fml.loading.FMLPaths/CORE]: Path FMLCONFIG is C:\Users\dmoyf\AppData\Roaming\.minecraft\config\fml.toml
