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 is sponsored by Object Computing Inc. in St. Louis Missouri. Please contact for support inquiries.

Getting Started

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 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
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 -XX:MaxPermSize=1G"

Performing a Release

Releases of Grails are automated by Travis CI.

To create a release perform the following steps.

First check that the tests are passing and all is well on Travis.

Next, update the Grails version in build.gradle and grails-core/src/test/groovy/grails/util/ and then push the changes to git:

$ git add build.gradle grails-core/src/test/groovy/grails/util/
$ git commit -m "Release Grails 3.0.1"
$ git tag v3.0.1
$ git push --tags
$ git push

After pushing these changes to the repository you must wait for the build to complete. During this phase the JAR files will be uploaded to the Grails Artefactory Repository.

The Travis CI build will automatically upload the tagged release to Github and be available of the Releases page.

Note: Although by default Grails uses Artefactory to resolve dependencies, it is useful to have them in Maven Central too. To ensure they go to Maven Central login to Sonatype OSS Nexus with your account details then "Close" and "Release" the staged JAR files.
