This tutorial assumes you have already

• Read the Pre-requisites
• Downloaded the latest Forge MDK
• Setup your mod folder as described at the top of the main Forge 1.14.4 tutorials page
• Read and followed 1.0 - Gradle Configuration
• Chosen IntelliJ from 1.1 - Importing the project into your IDE

IntelliJ

1. Open build.gradle as a Project by going to Menu > Import > build.gradle or File > Open > build.gradle > Open as Project to switch if you are already working on another project
   
   
2. Use default settings
   
   Personally I uncheck Create separate module per source set
   
3. Wait for build sync to download everything and finish
   This will take a while as Forge downloads everything and sets up your modding environment.
   
   
   
4. Refresh gradle project
   
   
5. Run the task genIntellijRuns to generate the run configs to run minecraft
   
   
6. Go to the Run Configurations menu and fix (set the module of) your runClient run configuration
   
   
   
   
   
   
   Save your changes
   All of these run configs launch minecraft.
   
   • runClient launches the minecraft client
   • runData launches minecraft in a special mode that only does the bare minimum required to automatically generate json files like recipes and blockstates.
   • runServer launches the minecraft server
7. Run the game
