Getting Started with Heroku
IntelliJ IDEA provides the ability to deploy your application to Heroku without using a command-line interface. You can deploy, redeploy and remove cloud applications right inside the IDE.

The Heroku integration plugin is installed. See Managing plugins to learn how to do this.
