deluan/grails.sh

Bash script for selecting and calling the correct Grails version when you have more than one version installed

Prerequisites

• All your Grails versions must be installed under the same base directory. Ex:

    /opt/grails-1.0.3
    /opt/grails-1.1.1
    /opt/grails-2.1.0.RC1
  

• GRAILS_HOME environment variable must be set and point to your "default" Grails installation

• cURL and unzip (If you want it to automatically pull missing versions)

• This script was tested on Mac OS X (Lion), but should work fine on Linux and Windows (with cygwin)

Installation

• Download the script: http://github.com/deluan/grails.sh/raw/master/grails
• Include the folder where it is installed in your PATH.
• Exclude $GRAILS_HOME/bin from your PATH

Usage

Using the script is as transparent as possible:

• If you invoke it from a project folder, it will detect the version used by the project and call the correct grails

  • If the required version does not exist locally, the script will attempt to download the version specified from grails amazon mirror

• If you invoke it from any other folder that does not contain a Grails project, it will call the "default" Grails installation

• If you want to call a specific Grails version (i.e. when doing an upgrade) you can specify the version you want in the first parameter.

  • If the version you specified does not exist locally, it will also attempt to download the version specified. Ex:

    $ grails 2.2.3 upgrade

• It tries to determine the command to run based on its name, so you can create symlinks for it to use the grails-debug command, or use it with Griffon. It should also work with any other tool that uses the same installation structure than Grails (like Groovy, Gradle)
