A barebones Java app, which can easily be deployed to Heroku.

This application supports the Getting Started with Java on Heroku article - check it out.

Make sure you have Java and Maven installed. Also, install the Heroku CLI.

$ git clone https://github.com/heroku/java-getting-started.git
$ cd java-getting-started
$ mvn install
$ heroku local:start

Your app should now be running on localhost:5000.

If you're going to use a database, ensure you have a local .env file that reads something like this:

DATABASE_URL=postgres://localhost:5432/java_database_name

$ heroku create
$ git push heroku master
$ heroku open
