For a quick and effortless start on Mac OSX, Linux, or Cygwin, you can use SDKMAN! (The Software Development Kit Manager) to download and configure any Grails version of your choice.

Installing with SDKMAN!

This tool makes installing Grails on any Unix based platform (Mac OSX, Linux, Cygwin, Solaris, or FreeBSD) easy.

Simply open a new terminal and enter:

$ curl -s https://get.sdkman.io | bash

Follow the on-screen instructions to complete installation.

Open a new terminal or type the command:

$ source "$HOME/.sdkman/bin/sdkman-init.sh"

Then install the latest stable Grails:

$ sdk install grails

If prompted, make this your default version. After installation is complete it can be tested with:

$ grails -version

That's all there is to it!
