Spigot/Bungeecord Hibernate - Invalid logger interface org.hibernate.internal.CoreMessageLogger-CodePudding

I tried using Hibernate ORM to handle my BungeeCord database mappings. I've used it before and had no problems doing so.

Now I revisited Minecraft programming and could not get Hibernate running.

My pom.xml is:

And my main is:

package io.jakobi.sessionutil;

import io.jakobi.sessionutil.database.entity.Action;
import io.jakobi.sessionutil.database.entity.Session;
import io.jakobi.sessionutil.database.repository.ActionRepository;

import org.hibernate.Hibernate;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.internal.CoreMessageLogger;

import java.io.File;

public class SessionUtil extends Plugin {

    private static final String HIBERNATE_CONFIG_FILE_NAME = "hibernate.cfg.xml";

    private SessionFactory sessionFactory;

    @Override
    public void onEnable() {
        sessionFactory = new Configuration()
            .configure(new File(this.getDataFolder().getAbsolutePath()   "/"   HIBERNATE_CONFIG_FILE_NAME))
            .addAnnotatedClass(Session.class)
            .addAnnotatedClass(Action.class)
            .buildSessionFactory();

        ActionRepository actionRepository = new ActionRepository(sessionFactory);
        SessionRepository sessionRepository = new SessionRepository(sessionFactory);

        registerListener(this, actionRepository, sessionRepository);
    }

    @Override
    public void onDisable() {
        if (this.sessionFactory != null) {
            this.sessionFactory.close();
        }
    }

    private void registerListener(SessionUtil instance, ActionRepository actionRepository, SessionRepository sessionRepository) {
        this.getProxy().getPluginManager().registerListener(instance, new PlayerJoinListener(sessionRepository));
        this.getProxy().getPluginManager().registerListener(instance, new PlayerQuitListener(sessionRepository));
        this.getProxy().getPluginManager().registerListener(instance, new PlayerChatListener(sessionRepository, actionRepository));
    }
}

The issue that I am facing is that on startup, the following exception is thrown:

A quick google search didn't really help. I found a comment saying I have to initialize the logger with Hibernate.initalize(object). I could not get that to work either.

Thanks in advance for any help! :)

CodePudding user response：

I don't know how class loading works in this "environment", but the hibernate-core.jar should contain a class called org.hibernate.internal.CoreMessageLogger_$logger, which is the logger implementation that apparently can't be found. Maybe the class loader is broken?

CodePudding user response：

Your maven shade plugin contains the following:

<configuration>
    <minimizeJar>true</minimizeJar>
</configuration>

This causes all the logging dependencies to be dropped while shading. Removing this line will fix the issue.
