You must meet the following requirements:

  • JDK8u40 as a minimum

  • JDK9

  • Gradle 4.7

You may used the included gradle wrapper script if you don’t have gradle installed.

Define the following environment variables:

export JAVA_8=/path/to/jdk8
export JAVA_9=/path/to/jdk9

Adapt these instructions to Windows settings if running on Windows.

Installing Gradle

  1. Download Gradle from http://gradle.org/downloads

  2. Unzip the file into a directory without spaces (recommended).

  3. Create a GRADLE_HOME environment variable that points to this directory.

  4. Adjust your PATH environment variable to include $GRADLE_HOME/bin (%GRADLE_HOME%\bin on Windows).

  5. Test your setup by invoking gradle --version.

  1. Follow the instructions found at http://sdkman.io/ to install SDKMAN.

  2. You need a POSIX environment if running Windows. We recommend using Babun Shell (http://babun.github.io/)

  3. Once SDKMAN is installed invoke sdk install gradle 4.7.

  4. Test your setup by invoking gradle --version.


GDub is a wrapper script that facilitates invoking gradle tasks anywhere within a Gradle project. It’s smart enough to use the gradle wrapper if available or your global gradle command. This is an optional download.
