Support for Maven wrapper

Change effective on 14 November 2016

Heroku’s support for Java applications built with Maven now includes support for Maven Wrapper. This is the recommend mechanism for defining a Maven version in your project. If Heroku detects a mvnw file in the root directory of your repository, it will use this script to launch the Maven process.

For more information on using Maven with Heroku, please see the Dev Center article on Java support.
