Setting up a Workspace

LiquidBounce is using Gradle, so make sure that it is installed properly. Instructions can be found on Gradle's website.

  1. Clone the repository using git clone
  2. CD into the local repository folder.
  3. Depending on which IDE you are using execute either of the following commands:
    • For IntelliJ: gradlew --debug setupDevWorkspace idea genIntellijRuns build
    • For Eclipse: gradlew --debug setupDevWorkspace eclipse build
  4. Open the folder as a Gradle project in your IDE.

Running LiquidBounce

  1. Open your IDE's run configuration window.
  2. Add the following to your projects VM options:
  3. Now simply launch LiquidBounce inside your IDE

Additional libraries


Mixins can be used to modify classes at runtime before they are loaded. LiquidBounce is using it to inject its code into the Minecraft client. This way, we do not have to ship Mojangs copyrighted code. If you want to learn more about it, check out its Documentation.


We appreciate contributions. So if you want to support us, feel free to make changes to LiquidBounce's source code and submit a pull request. Currently our main goals are the following:

  1. Improve LiquidBounce's performance.
  2. Re-work most of the render code.

If you have experience in one or more of these fields, we would highly appreciate your support.

You can’t perform that action at this time.
