I have a Macbook with Android Studio installed. Since I have projects that use Gradle (and Android Studio also uses Gradle), I would assume I have Gradle installed on my machine somewhere. However if I type `gradle` into the terminal I get `command not found`. So, do I have Gradle automatically installed because I have Android Studio, or do I have to run `brew install gradle` ?

I know this is a bad/silly question, but I just want to make sure I don't install Gradle twice.
