Install manually

Step 1. Download the latest Gradle distribution

The current Gradle release is version 4.10.2, released on 19 Sep 2018. The distribution zip file comes in two flavors:

• Binary-only
• Complete, with docs and sources

If in doubt, choose the binary-only version and browse docs and sources online.

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-4.10.2-bin.zip
$ ls /opt/gradle/gradle-4.10.2
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-4.10.2 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

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-4.10.2/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-4.10.2\bin. Click OK to save.

Step 4. Verify your installation

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

$ gradle -v

Upgrade with the Gradle Wrapper

If your existing Gradle-based build uses the Gradle Wrapper, you can easily upgrade by running the wrapper task, specifying the desired Gradle version:

$ ./gradlew wrapper --gradle-version=4.10.2 --distribution-type=bin

Note that it is not necessary for Gradle to be installed to use the Gradle wrapper. The next invocation of gradlew or gradlew.bat will download and cache the specified version of Gradle.

$ ./gradlew tasks
