JetBrains, the makers of IntelliJ IDEA, are continually working on improving support for Groovy, Grails, Griffon, Gradle as well as other GR8 technologies. Check out the latest news and tips and tricks at the JetBrains DZone or the IntelliJ IDEA blog. Consider also watching some of the practical screencasts.

Download & InstallationĀ 

Groovy support comes bundled with IntelliJ IDEA since version 8.

For IntelliJ IDEA version 7 you need to install the plugin via the IDEA plugin manager (you can find it listed as "JetGroovy"). After installing the plugin via the plugin manager, you will have to restart idea and then configure the plugin via the settings panel so that the plugin knows where to find your Groovy and (optionally) Grails installation directories.

Features

The Groovy support in IntelliJ IDEA provides a rich set of features for development with Groovy, Grails, Gradle, Griffon or GAnt. Here, we're listing the main features, but you can find out more on JetGroovy Groovy features page and the JetGroovy Grails features page.
