How to install a custom jar on your server

We provide a list of preinstalled server versions, but sometimes you may want to install a custom .jar file if your desired version or modpack is not included. Whether you're setting up a proxy server like BungeeCord or running a specialized modded server, you can easily upload your own .jar file to your server.

Why Install a Custom Server .jar?

Installing a custom .jar file allows you to:

Use unsupported versions: Run versions of Minecraft that may not be available in the default server lists.

Host modded servers: Install modded server software that enables unique gameplay features, such as custom mods or proxies.

Set up network proxies: Use proxy software like BungeeCord to link multiple servers and create a network of interconnected worlds.

Let's walk through the process step by step.

Requirements

You need a server customer .jar file, for the exemple, we will use "Bungeecord.jar" from https://ci.md-5.net/job/BungeeCord/

an FTP client such Filezilla or Winscp for FTP connection.
