No longer seems to work on Heroku

[sparkyspider]

Hi Joe,

I've been trying to deploy a Spring app on Heroku. It's crashing asking for JAVA_HOME. I've tried swapping the dependencies around as well as forking your buildpack to upgrade to lastest.

Hoping you can advise. When I left out the heroku/java it seemed to get further. I don't understand why the JAVA_HOME set by the script isn't sticking.

If I do the buildpack without heroku/java I seem to get much further...

Adding a note that my use case is a gradle app with build.gradle (not pom.xml as per Maven) but that it was working before so not sure what changed on Heroku's side.
