Grails is a framework used to build web applications with the Groovy programming language. The core framework is very extensible and there are numerous plugins available that provide easy integration of add-on features.

Grails development is lead by the Grails Foundation and is sponsored by Object Computing Inc. in St. Louis Missouri. Please contact [email protected] for support inquiries.

You need a Java Development Kit (JDK) installed, but it is not necessary to install Groovy because it's bundled with the Grails distribution.

To install Grails, visit https://grails.org/download.html and download the version you would like to use. Set a GRAILS_HOME environment variable to point to the root of the extracted download and add GRAILS_HOME/bin to your executable PATH. Then in a shell, type the following:

grails create-app sampleapp
cd sampleapp
grails run-app

To build Grails, clone this GitHub repository and execute the install Gradle target:

git clone https://github.com/grails/grails-core.git
cd grails-core
./gradlew install

If you encounter out of memory errors when trying to run the install target, try adjusting Gradle build settings. For example:

export GRADLE_OPTS="-Xmx2G -Xms2G -XX:NewSize=512m -XX:MaxNewSize=512m"

See RELEASE.md.
