ASF GitHub Bot commented on MAHOUT-2023:
----------------------------------------
Github user rawkintrevo commented on the issue:
https://github.com/apache/mahout/pull/353
I did two updates.
One, both scopts are included now. Because maven will automatically filter
the one that isn't a dependency, no conflicts here.
I also refactored to drop the scala-2.11, scala-2.10 profiles. It's all
handled by buildtools/change-scala-version.sh
In the parent pom you will still see $scala.version /
$scala.compat.version. These are only needed to handle the ant-copy plugin,
which is itsself a hack and should probably be removed, but requires
refactoring where and how the scala-shell picks up jars.
> Drivers broken, scopt classes not found
