I've just started modding, and I'm trying to make custom swords. When I try to import SwordItem, I get the error:

The import net.minecraft.world.item.SwordItem cannot be resolvedJava(268435846)

What confuses me is that other item classes work fine:

package io.github.xxx.denseswords.item;

import io.github.xxx.denseswords.DenseSwords;
import net.minecraft.world.item.Item; // works fine
import net.minecraft.world.item.ShovelItem; // works fine
import net.minecraft.world.item.SwordItem; // Error: The import cannot be resolved
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.RegistryObject;

Hi, have you found a solution to your problem? I ran into her too.

The SwordItem class doesn't exist in newer versions, Mojang moved the sword functionality to Data Components. Look at the sword registrations in the Items class for examples of this.
