Subject Re: Build fails on master (f90ad5d)
Date Wed, 05 Nov 2014 01:53:03 GMT
Nicholas,

Indeed, I was trying to use sbt to speed up the build. My initial
experiments with the maven process took over 50 minutes, which on a 4-core
2014 MacBookPro seems obscene. Then again, after the failed attempt with
sbt, mvn clean package took only 13 minutes, leading me to think that most
of the time was somehow being spent in downloading and building
dependencies.

Anyway, if sbt is supported it would be great to add docs about somewhere,
especially since, as you point out, most devs are using it.

Thanks for your help.

Alex
