Why does SBT compile just the last subproject? - scala

Question

I'm getting crazy, really :-(
Given the following SBT build file...
import sbt._
import sbt.Keys._
object BrixBuild extends Build {
lazy val buildSettings = Project.defaultSettings ++ Seq(
organization := "com.mycompany",
version := "0.1-SNAPSHOT",
scalaVersion := "2.10.0-RC3",
scalacOptions in Compile ++= Seq("-encoding", "UTF-8", "-deprecation", "-feature", "-unchecked"),
resolvers += Resolvers.typesafe,
target := file("target")
)
lazy val util = Project(
id = "brix-util",
base = file("brix-util"),
settings = buildSettings ++ Seq(
libraryDependencies ++= Dependencies.util
)
)
lazy val slick = Project(
id = "brix-slick",
base = file("brix-slick"),
settings = buildSettings ++ Seq(
libraryDependencies ++= Dependencies.slick
)
)
}
object Resolvers {
val typesafe = "Typesafe Releases" at "http://repo.typesafe.com/typesafe/releases"
}
object Dependencies {
private object Compile {
val commonsCodec = "commons-codec" % "commons-codec" % "1.7"
val slick = "com.typesafe" %% "slick" % "1.0.0-RC1"
}
private object Test {
val specs2 = "org.specs2" %% "specs2" % "1.12.3" % "test"
val slf4j = "org.slf4j" % "slf4j-nop" % "1.6.4" % "test"
val h2 = "com.h2database" % "h2" % "1.3.166" % "test"
}
val util = Seq(Compile.commonsCodec, Test.specs2, Test.slf4j)
val slick = Seq(Compile.slick, Test.specs2, Test.slf4j, Test.h2)
}
... only the last subproject get compiled. Why? Am I missing something?
Any help would be really appreciated. Tx.

You should define a "parent" project that aggregates the subprojects. For an example see https://github.com/typesafehub/scalalogging/blob/master/project/Build.scala.
