IDE/Project Setup

Recommended IDE: IntelliJ

It has solid Kotlin support and we will only be able to help you resolve IDE problems in IntelliJ.

Once installed, Set up your JDK to use the latest OpenJDK version.

Setting up a project

Clone a project from GitHub and open it in IntelliJ. From there, it should start importing it as a Gradle project and you'll soon get syntax highlighting and be able to build your project.

Note: Working on multiple projects

You may use our composite master project to open several projects at once. Note it slows down build times, so you may wish to limit yourself to one at a time.


You do not need to install anything to build. You can do it from command line or IntelliJ (running builds through IntelliJ will be more convenient)

This video shows how to run Gradle tasks like build, as well as how to work with Gradle in general. Feel free to watch the short clip or full video.

You can also find documentation here.

cd <insert project directory here>
gradlew.bat build
cd <insert project directory here>
./gradlew build

Configure gradle

Gradle has a global configuration file located at ~/.gradle/ (~ being your user directory). Create the file and add the lines below:

  • plugin_path will instruct our builds to copy the final jar into this path
  • paperweight.experimental.sharedCaches will reuse the same decompiled Minecraft server across projects, saving a lot of time
