S: I'd recommend making this a maven-enabled parameter with this as a default. This would allow it to be overridden if appropriate.

templates/dockerfile.vm lives in the classpath so I'm not sure what use this would have to a downstream developer.

Would we want to give the dev the option of using their own template / changing the existing template? If so, I can expand the velocity engine setup to look in the downstream's file system for a custom dockerfile template file first before deferring to the default in the habushu jar, then make additional documentation for how to do this in the README. Although I imagine someone with extensive customizations would instead disable the dockerfile generation portion before going willy-nilly on it with edits.

I don't think we need to default to looking on the file system first. The idea is to support extension I think. In which case it'd be pretty simple to get the custom template on Habushu's classpath, or change the Velocity configuration to add a new resource loader for template resolution.

Q/S: Instead of creating this new class, could we call PackageManager in its place?

[cpointe-ibllanos]

Good catch! Yeah there is a way we can convert the existing enumerator to strings.
