Grails Installation

Installation from Download

Prerequisites

Before you can start using Grails you will need to install a Java SDK (not just a JRE) and set the JAVA_HOME environment variable to the location of that SDK. The minimum required version of the SDK depends on which version of Grails you are using:

• Java SDK 1.4+ for Grails 1.0.x and 1.1.x
• Java SDK 1.5+ for Grails 1.2 or greater

Steps

• Download the latest Grails release
• Extract the archive into an appropriate location; typically C:\grails on Windows or ~/grails on Unix
• Create a GRAILS_HOME environment variable that points to the path where you extracted the archive (eg C:\grails on Windows or ~/grails on Unix)
• If you have not set the JAVA_HOME environment variable yet, create JAVA_HOME environment variable that points to the path where you have installed Java
• Append a reference to the "bin" directory within the Grails directory to your PATH variable (eg %GRAILS_HOME%\bin on Windows or $GRAILS_HOME/bin on Unix). Note that, for Windows, both PATH and GRAILS_HOME must be defined at the same environment variable level (eg. 'System variables') rather than across environment variable levels (eg. PATH under 'System variables' and GRAILS_HOME under 'User variables')
• Type "grails" at the command line, if a help message is displayed you are ready to start using Grails!
• If you get an error message, try to chmod +x the grails script inside the bin directory.

Installation from Git (The Version Control Repository)

Prerequisites

In order to start using Grails from Git you need to have the following:

• An installation of Java 1.5 or higher and have set your JAVA_HOME variable to the install location
• A Git client

Steps

• Check out Grails from the Git repository
• by running: git clone git://github.com/grails/grails-core.git
• Set the GRAILS_HOME environment variable to CHECKOUT_LOCATION/grails-core
• Add the $GRAILS_HOME/bin directory to your PATH environment variable
