This article is archived. Cauldron is no longer available for download. We recommend using Thermos now.
Cauldron allows you to run Forge mods and CraftBukkit plugins on your Minecraft server. To install Cauldron, you will need to download the installer, server, and BukkitCauldron files provided from Maeyanie’s distribution repository. Run the installer on your computer to download all of the required files, and then upload all of the files to your server. Afterwards, select and run cauldron-[version]-server.jar as the custom JAR where [version] represents the version number.
Bukkit, Spigot, and Cauldron all suffered from a legal dispute that caused them to be removed from public access. Different communities have taken some steps to work around this in a legal fashion. For Cauldron, Mayeanie, who was a core member of MCPC before it became MCPC-Plus or Cauldron, made a separate release. Others have verified that the files she worked on and released are safe, and their source came directly from Cauldron.
Older versions of MCPC-legacy and MCPC-Plus are no longer available anywhere legally or in a safe place. Please don’t download and install such files, as they may contain malware. As such, our guide will now only cover how to download and install Maeyanie’s Cauldron to your server.
- Determine the version of Minecraft you need to support. If you’re not sure, start your mod pack, wait for the first screen of Minecraft to load, and look on the lower-left corner. The available supported versions are 1.6.4, 1.7.2, and 1.7.10. Some mod packs, like B-Team, will require 1.6.4.
- Go to the Maeyanie Cauldron downloads page, and download the installer, server, and CauldronBukkit for the version that you determined in the previous step.
- Run the installer.
- Choose "Install Server" and install it into a folder that you can find later. Note: Sometimes the installer will skip a few required files. It may be a good idea to run the installer a few times, installing to the same folder, to ensure that you have all of the required files.
- Connect to your server FTP using FileZilla
- On the local site, navigate to where you installed the Cauldron files. Drag all of its contents (cauldron-...-server.jar, CauldronBukkit.jar, libraries, minecraft_server...jar) to the appropriate game folder on the remote site. Overwriting existing files should be fine. It’s unnecessary to upload the installer, as you won’t be able to run it on your server anyway.
- Login to Command Center.
- Go to the game update page (Click the gear icon above the graphs)
- Under "Custom JAR," install cauldron-...-server.jar.
- Start your server.
After installation and you start your server, your server console may indicate missing libraries. Repeat steps 3 and 4 at "Prepare the files on your computer" and then “Upload the files.” If you continue to experience the same message, contact support.
On Feed the Beast server mod packs like Direwolf20 1.6.4, your server may crash upon startup. Cauldron has made some changes that caused two diagnostic mods, MobiusCore and Opis, to become incompatible. View the exact error messages and steps to resolve the issue. If the errors you see are different than the ones in the tutorial, let us know, and we'll look into it for you.
If you’re running a new 1.7.10 server, you may need to agree to the Minecraft server EULA.
Chances are that you are using Minecraft version 1.7.10. Between 1.6.x and 1.7.x, the way the console logs information changed from STDERR to STDOUT. Without getting technical, your server will use STDERR by default and you will need to tell it to switch to STDOUT after making a 1.7.x server. Otherwise you may not see anything, or the only thing you see might be errors that are normally only in log files. You can do this by clicking on the gear icon in your Command Center console, going to game update, and changing the console settings.
