Installing Groovy-Grails on Ubuntu

Now a days I am working with Groovy/Grails. This is really awesome language. Installing this in Ubuntu is very easy and this can be done very fast and in easy way. So how I installed Groovy/Grails up and running.

First install openjdk and groovy. Since in ubuntu these 2 packages are already available. So install it via apt-get.

sudo apt-get install openjdk-6-jdk
sudo apt-get install groovy

java -version
java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8) (6b18-1.8-0ubuntu1)
OpenJDK Client VM (build 14.0-b16, mixed mode, sharing)

groovyConsole

Now for installing Grails. We need to install via binary zip file.
Get the latest Binary Zip file and save to some of your location.
Unzip the folder and move to /usr/share/grails/
I just moved grails to /usr/share/ because ubuntu install Groovy at /usr/share/groovy so making the similarity.

Now Set the JAVA_HOME and GRAILS_HOME path for your profile. Since we are installing Grails via zip binary so we need to tell the system that where is Grails and where is JAVA.

Open ~/.profiles file and add these lines at the top.

JAVA_HOME=/usr/lib/jvm/java-6-openjdk
GRAILS_HOME=/usr/share/grails
PATH=$PATH:/usr/share/grails/bin
export JAVA_HOME PATH
export GRAILS_HOME PATH

And logout and login again and do

printenv

This will show you that Grails path is set for our profile.

Now just say

ganu@ganu:/usr/share/grails$ grails

Use ‘grails help’ for more info or ‘grails interactive’ to enter interactive mode

DONE !! WOW.

How to check where Groovy-Grails combination is working.

Go to your development Grails folder.
