@arthfl would you please add an integration test that confirms this works when pushing to CF? There is an existing example for the nodejs-buildpack here.

Thanks!

@ryanmoran
Thanks for checking, added the integration test just now.

FYI: the tests aren't working with go 1.13 anymore: golang/go#34443
