Ryan Williams commented on SPARK-4501:
--------------------------------------

Would this ideally just fork out to some package manager depending on what 
system the user is apparently running, or try to download and build zinc source 
in a way that we've tried and determined to usually work (since apparently 
people keep running into pitfalls attempting to do this outside of {{brew}} on 
OSX), or what do you have in mind?

> Create build/mvn to automatically download maven/zinc/scalac

> For a long time we've had the sbt/sbt and this works well for users who want 
> to build Spark with minimal dependencies (only Java). It would be nice to 
> generalize this to maven as well and have build/sbt and build/mvn, where 
> build/mvn was a script that downloaded Maven, Zinc, and Scala locally and set 
> them up correctly. This would be totally "opt in" and people using system 
> maven would be able to continue doing so.
> My sense is that very few maven users are currently using Zinc even though 
> from some basic tests I saw a huge improvement from using this. Also, having 
> a simple way to use Zinc would make it easier to use Maven on our jenkins 
> test machines.
