# Installing Gradle

You can install the Gradle build tool on Linux, macOS, or Windows. This document covers installing using a package manager like SDKMAN!, Homebrew, or Scoop, as well as manual installation.

Use of the Gradle Wrapper is the recommended way to upgrade Gradle.

You can find all releases and their checksums on the releases page.

## Prerequisites

Gradle runs on all major operating systems and requires only a Java JDK version 7 or higher to run. To check, run `java -version`. You should see something like this:

    ❯ java -version
    java version "1.8.0_151"
    Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
    Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)

Gradle ships with its own Groovy library, therefore Groovy does not need to be installed. Any existing Groovy installation is ignored by Gradle.

Gradle uses whatever JDK it finds in your path. Alternatively, you can set the `JAVA_HOME` environment variable to point to the installation directory of the desired JDK.

## Installing with a package manager

SDKMAN! is a tool for managing parallel versions of multiple Software Development Kits on most Unix-based systems.

    ❯ sdk install gradle 4.6

Homebrew is "the missing package manager for macOS".

    ❯ brew install gradle

Scoop is a command-line installer for Windows inspired by Homebrew.

    ❯ scoop install gradle

Chocolatey is "the package manager for Windows".

    ❯ choco install gradle

MacPorts is a system for managing tools on macOS:

    ❯ sudo port install gradle

↓ Proceed to next steps

## Installing manually

### Step 1. Download the latest Gradle distribution

The distribution ZIP file comes in two flavors:

- Binary-only (bin)

- Complete (all) with docs and sources

Need to work with an older version? See the releases page.

### Step 2. Unpack the distribution

#### Linux & MacOS users

Unzip the distribution zip file in the directory of your choosing, e.g.:

    ❯ mkdir /opt/gradle
    ❯ unzip -d /opt/gradle gradle-4.6-bin.zip
    ❯ ls /opt/gradle/gradle-4.6
    LICENSE  NOTICE  bin  getting-started.html  init.d  lib  media

#### Microsoft Windows users

Create a new directory `C:\Gradle` with File Explorer.

Open a second File Explorer window and go to the directory where the Gradle distribution was downloaded. Double-click the ZIP archive to expose the content. Drag the content folder `gradle-4.6` to your newly created `C:\Gradle` folder.

Alternatively you can unpack the Gradle distribution ZIP into `C:\Gradle` using an archiver tool of your choice.

### Step 3. Configure your system environment

For running Gradle, firstly add the environment variable `GRADLE_HOME`. This should point to the unpacked files from the Gradle website. Next add `GRADLE_HOME/bin` to your `PATH` environment variable. Usually, this is sufficient to run Gradle.

#### Linux & MacOS users

Configure your `PATH` environment variable to include the `bin` directory of the unzipped distribution, e.g.:

    ❯ export PATH=$PATH:/opt/gradle/gradle-4.6/bin

#### Microsoft Windows users

In File Explorer right-click on the `This PC` (or `Computer`) icon, then click `Properties` → `Advanced System Settings` → `Environmental Variables`.

Under `System Variables` select `Path`, then click `Edit`. Add an entry for `C:\Gradle\gradle-4.6\bin`. Click OK to save.

↓ Proceed to next steps

## Verifying installation

Open a console (or a Windows command prompt) and run `gradle -v` to run gradle and display the version, e.g.:

    ❯ gradle -v

    ------------------------------------------------------------
    Gradle 4.6
    ------------------------------------------------------------

If you run into any trouble, see the section on troubleshooting installation.

You can verify the integrity of the Gradle distribution by downloading the SHA-256 file (available from the releases page) and following these verification instructions.

## Next steps

Now that you have Gradle installed, use these resources for getting started:

- Create your first Gradle project by following the Creating New Gradle Builds tutorial.

- Sign up for a live introductory Gradle training with a core engineer.

- Learn how to achieve common tasks through the command-line interface.

- Configure Gradle execution, such as use of an HTTP proxy for downloading dependencies.

- Subscribe to the Gradle Newsletter for monthly release and community updates.

## Getting help

You might check the user guide at `GRADLE_HOME/docs/userguide/userguide.html`. It is also available on the Gradle web site. Typing `gradle help` prints the command line help. Typing `gradle tasks` shows all the tasks of a Gradle build.
