Shawn Heisey commented on SOLR-13665:
-------------------------------------
bq. so the reason why zookeeper project can get away with only those two is
because they use transitive dependency resolution while we don't
TL;DR comment.
If I have read the intent properly, the new Gradle build will be set to
primarily transitive dependencies. I think we should be using those for the
most part, except for situations where we KNOW we don't need something that
would normally be included, and for those we should probably be using
exclusions rather than non-transitive. IMHO.
