Grace is a fork of Grails 5 that started development in early 2022, it's a powerful and open-source One-Person web framework used to build enterprise-grade Spring Boot applications with the powerful Groovy programming language. The core framework is very extensible and there are numerous Plugins available that provide easy integration of add-on features.
You need a Java Development Kit (JDK) installed, but it is not necessary to install Groovy because it's bundled with the Grace distribution.
To install Grace, visit https://github.com/graceframework/grace-framework/releases and download the version you would like to use. Set a GRACE_HOME
environment variable to point to the root of the extracted download and add GRACE_HOME/bin
to your executable PATH
. Then in a shell, type the following:
grace create-app com.example.blog
cd blog
grace run-app
To build Grace, clone this GitHub repository and execute the install Gradle target:
git clone https://github.com/graceframework/grace-framework.git
cd grace-framework
./gradlew pTML zipDist
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"
For installation instructions see INSTALL.txt.
