Description
The second part (after #1559) of eliminating dependencies on
SCALA_VERSION
. This time within target attributes. Together with #1560 we should be all done.This change extensively uses the new
select_for_scala_version
macro (#1563).I tried my best to emerge the most correct intention, but in many cases the choice is rather arbitrary (e.g.
any_2
+any_3
vs.before_3
+since_3
vs.any_2
+default
)Motivation
#1290.
