Command line tool to deploy JVM applications directly to Heroku without pushing to a Git repository. It uses Heroku's Platform API. This can be useful when deploying from a CI server, deploying pre-built JAR or WAR files.
It will automatically include and configure a Tomcat server via webapp-runner if a WAR file is deployed.
Important
This repository previously contained Heroku's Maven Plugin for deploying JVM applications. This plugin is no longer maintained. Customers currently using the Maven Plugin can use the new Heroku JVM application deployer CLI to deploy JAR and WAR files to Heroku without using Git.
The code of the last Heroku Maven plugin release can be found here: https://github.com/heroku/heroku-jvm-application-deployer/tree/3.0.7
Download the JAR file from the latest release on GitHub. Older releases can be downloaded from the GitHub releases list.

This plugin uses Heroku's Platform API and thus requires an API key to function. If you have the Heroku CLI installed and logged in with heroku login, the plugin will automatically pick up your API key. Alternatively, you can use the HEROKU_API_KEY environment variable to set your API key:
$ HEROKU_API_KEY="xxx-xxx-xxxx" java -jar heroku-jvm-application-deployer.jar ...
