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:
$ heroku create $ git push heroku main $ heroku open
