Hi everyone! Today I was trying to create a Datastore for my Proxmox Backup Server installation on my WD MyCloud NAS that I mounted over SSHFS. While trying to create the datastore, I got the following error in the GUI: Huh, that’s weird – Proxmox failed to create the “fde6” directory, claiming it already exists….

Many people who are using the maven-shade-plugin commonly set <createDependencyReducedPom> to false for reasons beyond my grasp. This is generally a bad idea, as it can lead to problems if you’re writing a library, and has absolutely no advantages. Here’s a rule of thumbs: If your project shades dependencies, it should create a dependency-reduced-pom.xml. The…

Hi there! Today I’m going to explain how to setup a multi-module project using maven to support different NMS versions. Important notes about this tutorial: Every step will have detailled screenshots using IntelliJ. I explicitly chose not to include everything as copy/pastable source code, but normal screenshots (you can click on them to show them…

Spigot uses Log4j to log console output, hence making it easy to listen to incoming console messages, or to block certain console messages from appearing. Prequisities You need to have Log4J on your classpath. We simply add the dependency to our pom.xml using the provided scope, as Spigot already contains those classes on runtime: Create…

Sometimes, people suggest you to change something in your pom.xml, and then IntelliJ starts to complain: That is totally normal. You simply have to click the “maven reload button” in IntelliJ. Maven will then continue to download the required dependency/plugin, if it’s available. After a few seconds, everything should be fine. You can find the…

If you’re using maven for your Spigot plugins (which you should do), it’s easy to make maven automatically save your plugin’s .jar in your plugins folder. There’s two ways of doing this: 1. The lazy way (not recommended) If you only work alone on one computer, you can just directly declare the output location in…

When you want to spawn a custom entity, e.g. with a custom name or certain items equipped, you must use the method World#spawn(Location, Class<T extends Entity>, Consumer<T>) unless you give a shit about compatibility with other plugins. I’ll explain why. The shitty way Usually, you can easily spawn entities like this: That is fine, as…

Java allows you to use the so called “init blocks”. You can declare static and instance init blocks. The static init blocks will run exactly once, when the ClassLoader loads the class that declares it, and the instance init blocks run everytime you construct a new object, after the actual constructor ran. The general order…

Some people are confused about what the difference between Bukkit, Spigot-API, CraftBukkit and Spigot is, so I’ll try to explain. Bukkit is the basic API Bukkit contains all the usual interfaces and enums, like org.bukkit.entity.Player or org.bukkit.Material. For most plugins, this is all you need. It does not contain any implementations, meaning: you cannot “run”…

If you are switching from Spigot’s mappings (with class names like EntityZombie, WorldServer, PacketPlayOutSpawnEntity…) to Mojang mappings, you will notice that many of the classes you were using can’t be found anymore, since they now have different names. You will have to change all your references to those classes to their new names. Setup Mojang…
