Java support upgrades Maven version to 3.3.1
Change effective on 18 March 2015
Heroku’s Java support has upgraded the default version of Maven to 3.3.1. To use this new version, create a
system.properties file in the root of your application (or modify the existing file) and add this line:
You may also select 3.0.5, 3.1.1 or 3.2.5. If you are already using an older version of Maven, you will not be upgraded to the new version by default. You must specify the version in
system.properties to receive the upgrade.
For more information on Maven and its versions, see the Apache Maven documentation. See the Dev Center for more information on Heroku Java Support.
