How to Install Gradle

Gradle is a dependency management / build tool that combines the best of Maven and Ant, making it an extremely powerful and customizable tool. It also uses a sleek Groovy DSL instead of the XML approach of Maven and Ant and is my personal tool-of-choice when I start a new project. Here’s how to install. I’ll write a future post to get us started with some Gradle projects.

1. Install Java

First you need to have the Java JDK (Java Development Kit) installed; having the JRE (Java Runtime Environment) is not enough. To check if you have the JDK installed, open a command prompt or terminal and type javac -version. If you have a JDK
 
installed, you will see your javac version output, eg. javac 1.7.0_01. If you get an error that javac is not a recognized command, download and install the Java JDK.

2. Download Gradle

3. Unpack and Set System variables

Windows

  1. Unzip the Gradle download to the folder to which you would like to install Gradle, eg. “C:\Program Files”. The subdirectory gradle-x.x will be created from the archive, where x.x is the version.
  2. Add location of your Gradle “bin” folder to your path. Open the system properties (WinKey + Pause), select the “Advanced” tab, and the “Environment Variables” button, then add “C:\Program Files\gradle-x.x\bin” (or wherever you unzipped Gradle) to the end of your “Path” variable under System Properties. Be sure to omit any quotation marks around the path even if it contains spaces. Also make sure you separated from previous PATH entries with a semicolon “;”.
  3. In the same dialog, make sure that JAVA_HOME exists in your user variables or in the system variables and it is set to the location of your JDK, e.g. C:\Program Files\Java\jdk1.7.0_06 and that %JAVA_HOME%\bin is in your Path environment variable.
  4. Open a new command prompt (type cmd in Start menu) and run gradle –version to verify that it is correctly installed.

Mac/Linux

  1. Extract the distribution archive, i.e. gradle-x.x-bin.tar.gz to the directory you wish to install Gradle. These instructions assume you chose /usr/local/gradle. The subdirectory gradle-x.x will be created from the archive.
  2. In a command terminal, add Gradle to your PATH variable: export PATH=/usr/local/gradle/gradle-x.x/bin:$PATH
  3. Make sure that JAVA_HOME is set to the location of your JDK, e.g. export JAVA_HOME=/usr/java/jdk1.7.0_06 and that $JAVA_HOME/bin is in your PATH environment variable.
  4. Run gradle –version to verify that it is correctly installed.

You now have Gradle set up! Stay tuned for another post on how to build a simple Gradle project.

    And then, enable the wrapper so the others devs don’t have to install it ;)

  2. If you’re on Mac/linux, you can simply install GVM. It downloads, unpacks, and sets up your environment for you. (And makes it easier to change the version of grails/gradle you’re using, to boot) http://gvmtool.net/
