[CUSTOM CODE] ClassDefNotFoundError

Here's the one custom code procedure I have in the mod (the files for which I have rebuilt before producing this error again), which utilizes an apparently working API from SereneSeasons mod:

package net.mcreator.viticulture;

import net.minecraft.world.World;

import java.util.HashMap;

import sereneseasons.api.season.ISeasonState;
import sereneseasons.api.season.SeasonHelper;
import sereneseasons.api.season.Season;
import sereneseasons.api.season.Season.SubSeason;

@Elementsviticulture.ModElement.Tag
public class MCreatorProcedureCheckSeason extends Elementsviticulture.ModElement {
	public MCreatorProcedureCheckSeason(Elementsviticulture instance) {
		super(instance, 80);
	}

	public static void executeProcedure(java.util.HashMap<String, Object> dependencies) {
		double LocalCurrentSeason = 0;
		LocalCurrentSeason = (double) 0;
		World world = (World) dependencies.get("world");

	if (SeasonHelper.getSeasonState(world).getSubSeason() == Season.SubSeason.EARLY_SPRING) {
		LocalCurrentSeason = 1;
		System.out.println(LocalCurrentSeason);
	}
	if (SeasonHelper.getSeasonState(world).getSubSeason() == Season.SubSeason.MID_SPRING) {
		LocalCurrentSeason = 2;
	}
	if (SeasonHelper.getSeasonState(world).getSubSeason() == Season.SubSeason.LATE_SPRING) {
		LocalCurrentSeason = 3;
	}
	if (SeasonHelper.getSeasonState(world).getSubSeason() == Season.SubSeason.EARLY_SUMMER) {
		LocalCurrentSeason = 4;
	}
	if (SeasonHelper.getSeasonState(world).getSubSeason() == Season.SubSeason.MID_SUMMER) {
		LocalCurrentSeason = 5;
	}
	if (SeasonHelper.getSeasonState(world).getSubSeason() == Season.SubSeason.LATE_SUMMER) {
		LocalCurrentSeason = 6;
	}
	if (SeasonHelper.getSeasonState(world).getSubSeason() == Season.SubSeason.EARLY_AUTUMN) {
		LocalCurrentSeason = 7;
	}
	if (SeasonHelper.getSeasonState(world).getSubSeason() == Season.SubSeason.MID_AUTUMN) {
		LocalCurrentSeason = 8;
	}
	if (SeasonHelper.getSeasonState(world).getSubSeason() == Season.SubSeason.LATE_AUTUMN) {
		LocalCurrentSeason = 9;
	}
	if (SeasonHelper.getSeasonState(world).getSubSeason() == Season.SubSeason.EARLY_WINTER) {
		LocalCurrentSeason = 10;
	}
	if (SeasonHelper.getSeasonState(world).getSubSeason() == Season.SubSeason.MID_WINTER) {
		LocalCurrentSeason = 11;
	}
	if (SeasonHelper.getSeasonState(world).getSubSeason() == Season.SubSeason.LATE_WINTER) {	
		LocalCurrentSeason = 12;
	}
    
	viticultureVariables.WorldVariables.get(world).GlobalCurrentSeason = (double) (LocalCurrentSeason);
	viticultureVariables.WorldVariables.get(world).markDirty();
	}
}

 

When I run, the console gives me this:

Appears to be an issue with net.minecraft.world.world but I don't know nearly enough about what I'm doing to figure out how to fix it.

Thanks in advance for help figuring this out!

Seems that API is using reflection and the class it is looking for is nor present.
