Joe Crobak commented on KAFKA-1419:
-----------------------------------
I tried out this patch earlier today, and I have a few pieces of feedback:
* I'm not sure it's possible to support both scala 2.8 and 2.11 at the same
time while using the zinc compiler. 2.8 seems to require gradle 1.6/zinc 0.2.5,
and 2.11 requires gradle 2.0/zinc 0.3.0+. It's possible that there's a version
in between that supports them, but I didn't do the binary search. Switching to
{{scalaCompileOptions.useAnt = true}} seems to compile all scala versions for
me.
* I think the {{jarAll}}, {{srcJarAll}} and other `*All` tasks should be
updated to include scala 2.11.
* scala 2.9 support seems to be broken by two things: 1) several {{else{}}}
clauses were formerly scala 2.9 specific but were converted to be scala 2.11
specific. 2) wrong zinc version being selected.
* Moving {{BeanProperty}} from {{scala.reflect}} to {{scala.beans}} is
backwards incompatible with scala <2.10. it's likely better to remove the
{{BeanProperty}} dep and implement {{def getBuffer = buffer}} in those two
places.
* scala.gradle needs an override for 2.11 like it has for 2.10.
I have a feeling that trying to support 4 versions of scala is going to be a
pain in the long run—when can scala 2.8 (and also 2.9) be dropped?
