Forge server not running


Recommended Posts

I am trying to run a forge server on linux Ubuntu but I'm having trouble using mods, the normal minecraft server jar seems to work but whenever I try and run the forge one so I can use mods I get this error- 

A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException

    • EDIT: NVM, the enchantment ID was wrong and that was causing the issue. Not sure why it doesn't let me delete this post Hi, I'm trying to make a "smelting" enchantment Global Loot Modifier, but for some reason the game could not decode its related JSON file, altough is applying the Loot Modifier to every single loot When I join a world I get this error in the console   [01:08:01] [Render thread/WARN] [ne.mi.co.lo.LootModifierManager/]: Could not decode GlobalLootModifier with json id mineworld:enchantments/fiery_touch - error: Not a json array: {"condition":"minecraft:match_tool","predicate":{"enchantments":[{"enchantment":"mineworld:smelting","levels":{"min":1}}]}} The GLM Json file is the following { "type": "mineworld:fiery_touch", "conditions": [ { "condition": "minecraft:match_tool", "predicate": { "enchantments": [ { "enchantment": "mineworld:smelting", "levels": { "min": 1 } } ] } } ] } And this is the LootModifier class   package org.mineworld.loot; import com.google.common.base.Suppliers; import com.mojang.serialization.Codec; import com.mojang.serialization.codecs.RecordCodecBuilder; import it.unimi.dsi.fastutil.objects.ObjectArrayList; import net.minecraft.core.RegistryAccess; import net.minecraft.world.Container; import net.minecraft.world.SimpleContainer; import net.minecraft.world.item.ItemStack; import net.minecraft.world.item.crafting.Recipe; import net.minecraft.world.item.crafting.RecipeManager; import net.minecraft.world.item.crafting.RecipeType; import net.minecraft.world.level.Level; import net.minecraft.world.level.storage.loot.LootContext; import net.minecraft.world.level.storage.loot.parameters.LootContextParams; import net.minecraft.world.level.storage.loot.predicates.LootItemCondition; import net.minecraftforge.common.loot.IGlobalLootModifier; import net.minecraftforge.common.loot.LootModifier; import net.minecraftforge.items.ItemHandlerHelper; import org.jetbrains.annotations.NotNull; import org.mineworld.MineWorld; import java.util.List; import java.util.Optional; import java.util.function.Supplier; import java.util.stream.IntStream; /** * {@link MineWorld MineWorld} loot modifier for smelting a drop from a block */ public final class FieryTouchModifier extends LootModifier { /** * {@link Supplier<Codec> The loot codec supplier} */ public static final Supplier<Codec<FieryTouchModifier>> CODEC = Suppliers.memoize(() -> RecordCodecBuilder.create(inst -> codecStart(inst).apply(inst, FieryTouchModifier::new))); /** * Constructor.

    • Why are you doing this instead of just playing the sound using the level or the player method? 
    • You can use  event.getEntity().level()
