Scott Carey commented on KAFKA-854:
-----------------------------------
1. It is probably easier to review by looking at the final result than the
diffs. The purpose was to simplify the build, following DRY principles and
what appears to be the style that the latest sbt encourages:
* using sbt files for settings and .scala files for build definitions and
cross-module dependencies. Every sample / tutorial I found seemed to indicate
that this was standard convention (none were passing settings in when defining
the Project).
2. All version declarations in one file, centrally, with the DRY principle. I
could not find a way to do this in the base .sbt file since you can only set
configuration keys there, not define variables. If you want to see or change a
dependency version, there is only one place to go. Unlike Maven, SBT does not
provide a standard place to configure your dependency versions to promote
sharing across multiple projects.
