Use Loom to develop mods

To get started developing your own mods please follow the guide on Setting up a mod development environment.

This guide assumes you are using IntelliJ IDEA, other IDE's have not been tested; your experience may vary.

Import as a Gradle project by opening the build.gradle
Create a Gradle run configuration to run the following tasks build publishToMavenLocal -x test. This will build Loom and publish to a local maven repo without running the test suite. You can run it now.
Prepare a project for using the local version of Loom:
- A good starting point is to clone the fabric-example-mod into your working directory
- Add mavenLocal() to the repositories:
  - If you're using id 'fabric-loom' inside plugins, the correct repositories block is inside pluginManagement in settings.gradle
  - If you're using apply plugin: for Loom, the correct repositories block is inside buildscript in build.gradle
- Change the loom version to 0.6.local. For example id 'fabric-loom' version '0.6.local'
Create a Gradle run configuration:
- Set the Gradle project path to the project you have just configured above
- Set some tasks to run, such as clean build you can change these to suit your needs.
- Add the run configuration you created earlier to the "Before Launch" section to rebuild loom each time you debug
You should now be able to run the configuration in debug mode, with working breakpoints.
