This mod will stop Forge mods from loading - it does not allow Forge and Quilt mods to be used together!

Make sure you back up before you join worlds where you have used Forge mods previously - as all the blocks/items added by those mods will disappear.

JumpQuilt

JumpQuilt is a mod that allows the use of Quilt mods in CurseForge modpacks, by loading Quilt as if it were a Forge mod. It is a fork of Jumploader, which was well-known for doing this with Fabric until CurseForge got native Fabric support. It only loads if your game was launched from Forge/ModLauncher, so it won't do anything if your Minecraft launcher already supports Quilt.

What it does

Loads Quilt instead of Forge, from a Forge installation.
Automatically loads the latest Fabric loader version for your version of the game, with no required configuration.
If necessary, loads the unpatched Minecraft game, so that Quilt can be used with it.
Ensures that Quilt and Mixin don't see the classes loaded by ModLauncher.

What it doesn't do

JumpQuilt doesn't let you run Quilt mods with Forge or Forge mods with Quilt - it hijacks the launching process so that Forge never loads. See Patchwork for a project aiming to let you use Forge mods with Quilt.

Requirements

Requires a Forge version that uses ModLauncher (or ModLauncher on it's own, without Forge) - this usually means 1.13 or newer.

Support

Please make an issue on the Github issue tracker if you have any issues with the mod.

Updating Quilt loader

JumpQuilt installs the latest version of Quilt loader when you first launch the game, but it doesn't automatically update it afterwards to prevent breaking existing modpacks. If you want to change the version it installs, edit the pinQuiltLoaderVersion property in the jumpquilt.json config file to the version you want.
