The Procfile CNB has just moved Docker Hub repo:
heroku/buildpacks-procfile#219
Instead of updating the repo URL used in the tests, I've switched the tests to use the Procfile CNB from the builder image instead.
This is now safe to do, since there is now only ever one Procfile version in the builder after:
heroku/buildpacks-jvm#608
heroku/buildpacks-nodejs#696
Using the Procfile version from the builder has a few advantages:
There is the chance of breakage, should the upstream Procfile CNB make a breaking change, however, that should be very rare and will only affect tests, and seeing that breakage here is actually kinda the point :-)
