# Gradle
Gradle is used to build OpenWhisk. It does not need to be pre-installed as it installs itself using the [Gradle Wrapper](https://docs.gradle.org/current/userguide/gradle_wrapper.html). To use it without installing, simply invoke the `gradlew` command at the root of the repository. You can also install `gradle` via [`apt`](http://linuxg.net/how-to-install-gradle-2-1-on-ubuntu-14-10-ubuntu-14-04-ubuntu-12-04-and-derivatives/) on Ubuntu or [`brew`](http://www.brewformulas.org/Gradle) on Mac. In the following we use `gradle` and `gradlew` as synonymous.
