Subject Re: picocli-based CliBuilder backwards compatibility
Date Sun, 25 Mar 2018 07:16:10 GMT
I think they are much less widely used than other features so feel free to
change them. If similar functionality is available via picocli, please use
the same property name if it makes sense to expose that functionality for
greater control.

We will likely create a separate module (groovy-cli-commons or similar)
with the existing CliBuilder implementation (but with probably a package
name change) that won't be referenced in the groovy-all pom. If folks are
relying on those bits of the functionality, they can use the legacy
version. The goal should be to have commons-cli being a dependency of only
that module.

Cheers, Paul.
