Creating Forge Modpack: Exception message: java.lang.ClassNotFoundException: org.yaml.snakeyaml.DumperOptions

I am currently trying to make a mod with a database using SnakeYAML. I am currently using VSCODE, Minecraft forge version 1.19, and Forge Gradle. I was previously trying to use SQLite, but had the same error so I switched to Snake.

I have experience with Java, but no experience with SnakeYAML or Minecraft modding so let me know if I'm missing something.

I have cleaned and rebuilt multiple times.  I have also assured that SnakeYAML is being built into the .jar, which it is (It is listed as a dependency for the jar when built.)

Exception message: java.lang.ClassNotFoundException: org.yaml.snakeyaml.DumperOptions

DatabaseManager (where I intialize the SnakeYAML class):

package me.cadenwolfdog.furclasses.Data;

import me.cadenwolfdog.furclasses.PlayerClass;
import org.yaml.snakeyaml.DumperOptions;
import org.yaml.snakeyaml.Yaml;

import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import java.util.UUID;

public class DatabaseManager {
    private static final File configFile = new File("mods/FurClasses/players.yaml");
    private static final DumperOptions options = new DumperOptions();
    private static final Yaml yaml = new Yaml(options);

    private static final Map<UUID, PlayerClass> playerData = new HashMap<>();
    

    public static void initializeDatabase() {
        configFile.getParentFile().mkdirs();

        if (!configFile.exists()) {
            try {
                configFile.createNewFile();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }


    public static void setPlayerClass(UUID playerUUID, PlayerClass playerClass) {
        playerData.put(playerUUID, playerClass);

        try (FileWriter writer = new FileWriter(configFile)) {
            yaml.dump(playerData, writer);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }


    public static PlayerClass getPlayerClass(UUID playerUUID) {
        return playerData.get(playerUUID);
    }
}

The common set up where I am running the database initialization:

private void commonSetup(final FMLCommonSetupEvent event) {
        // Some common setup code
        LOGGER.info("HELLO FROM COMMON SETUP");
        try{
            DatabaseManager.initializeDatabase();
        }catch (Exception e){
            LOGGER.info("EXCEPTION MADE: " + e.toString());
        }
        finally {
            LOGGER.info("Database initialization successful.");
        }
    }
