Heroku buildpack: Grails

This is a Heroku buildpack for building and deploying Grails apps on Heroku.

Grails 2 support is deprecated and ending on June 1, 2017. For Grails 3, please see the documentation for Deploying Gradle Apps on Heroku, as Grails 3 and onward use Gradle as their packaging mechanism.

Usage

Create a Git repository for a Grails 1.3.7 or 2.0 app:

$ cd mygrailsapp
$ ls
application.properties    lib        src               target    web-app
grails-app                scripts    stacktrace.log    test
$ grails integrate-with --git
| Created Git project files..
$ git init
Initialized empty Git repository in /Users/jjoergensen/mygrailsapp/.git/
$ git commit -m init
[master (root-commit) 7febdd9] init
 58 files changed, 2788 insertions(+), 0 deletions(-)
 create mode 100644 .classpath
 create mode 100644 .gitignore
 create mode 100644 .project
 create mode 100644 application.properties
...

Create a Heroku app

$ heroku create
Creating vivid-mist-9984... done, stack is cedar

Git remote heroku added

Push the app to Heroku

$ git push heroku master

Auto-detection

Heroku auto-detects Grails apps by the existence of the grails-app directory in the project root and the application.properties file is also expected to exist in the root directory.

Using a Customized (Forked) Build Pack

This is the default buildpack repository for Grails. You can fork this repo and tell Heroku to use the forked version by passing the --buildpack option to heroku create:

$ heroku create --buildpack http://github.com/jesperfj/heroku-buildpack-grails.git
