Install Gradle and configure $GRADLE_HOME on a Mac

Requisition:

Gradle requires Java version 7 or higher to be installed on your machine. To check it, run:

$ java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

Install Gradle

In this example I would use Homebrew. To install Gradle using Homebrew run:

$ brew update && brew install gradle

Configure $GRADLE_HOME

In your .bash_profile file (usually located in the user's home directory) add the following line to update PATH variable:

...
export GRADLE_HOME=/usr/local/opt/gradle/libexec
export PATH=$GRADLE_HOME/bin:$PATH

Save the file. Right now, it's time to tell our environment to use changed .bash_profile by running the following command:

$ source .bash_profile

Verify the installation:

$gradle -v
