Grails Startup with IntelliJ IDEA

I started a toy project just to give Grails a try and want to share the project setup, and other steps. I were really impressed by the demo applications: painless, easy startup and CRUD applications, but yes a bit too late but I were really busy at my new job, and also trying to get used to my new country, and of course I admit that I am a bit lazy too
After reading the Getting Started with Grails free booklet, and well prepared Grails Documentation I started playing with it

Well startup steps with IntelliJ IDEA:

• Download the Grails
• Set the GRAILS_HOME and add it to path environment variable
• Download the Grails IntelliJ plugin JetGroovy (If you use IntelliJ IDEA 8 you should skip this step, since JetGroovy plugin is bundled in this version otherwise IDE would crash)
  
• Just unzip the JetGroovy to plugins folder
• Change the installation directory for Grails from Settings/Groovy&Grails
• Update the JetGroovy plugin from Settings/Plugins (There were some mysterious errors at IntelliJ like crashing at Backspace key )

My first HelloGrails application had the below error, after playing with the Grails version and trying an older version: grails-1.0.4, I realized that the Groovy was also necessary for JetGroovy plugin. I had already installed groovy but GROOVY_HOME environment setting was missing, but still I could not get the point: Why can’t I use Grails without Groovy @IntelliJ?

Anyway, you can add two more steps for Grails startup for IntelliJ IDEA users:

• Download the Groovy
• Set the GROOVY_HOME and add it to path environment variable

My startup configuration:
grails-1.0.4
groovy-1.5.7
jdk1.6.0_07
IntelliJ IDEA 7.0.4
