1. change power mode

scala> :power
** Power User mode enabled - BEEP BOOP SPIZ **
** :phase has been set to 'typer'.          **
** scala.tools.nsc._ has been imported      **
** global._ and definitions._ also imported **
** Try  :help,  vals.<tab>,  power.<tab>    **

以下のtreeのsbt0.11のbranchをbuildして使ってみた

https://github.com/harrah/xsbt/tree/c256c03f48bf0c92772803c42219f5091d65a6bf

sbtの勉強したい
デフォルトでimportやimplicit定義されてるものとか知りたい

そして2.9系だと

sbtの0.10系を使っているprojectが、どんなことやってるか調べた

scalaz

https://github.com/scalaz/scalaz/blob/master/project/ScalazBuild.scala
201行
コード生成してる
複数のScalaのversionのCross Build
sxr の生成。sxrの生成のために scalaz-full というプロジェクトを定義してる?

sbt

generate sxr project

save build.sbt
compile

$ sbt compile
