scala - How to set default dependencies for all subprojects in SBT? -


trying understand how set sbt subprojects. correct way set default dependencies sub projects?

i tried this, sub projects weren't picking of dependencies (they downloaded fine).

import sbt._  class myprojects(info: projectinfo) extends defaultproject(info) {   val proja = project("proja", "projecta")   val projb = project("projb", "projectb")    val akkarepo = "akka maven2 repo" @ "http://www.scalablesolutions.se/akka/repository/"   val multiverserepo = "multiverse maven2 repo" @ "http://multiverse.googlecode.com/svn/maven-repository/releases/"   val guiceyfruitrepo = "guiceyfruit maven2 repo" @ "http://guiceyfruit.googlecode.com/svn/repo/releases/"   val jbossrepo = "jboss maven2 repo" @ "https://repository.jboss.org/nexus/content/groups/public/"    val junit = "junit" % "junit" % "4.5" % "test"   val scalatest = "org.scalatest" % "scalatest" % "1.2" % "test"   val akka = "se.scalablesolutions.akka" % "akka-core_2.8.0" % "0.10" }

then, based on this tried following. worked, it's not expecting have do. isn't there simpler set default dependencies subprojects?

import sbt._    class myprojects(info: projectinfo) extends defaultproject(info) {   val proja = project("proja", "projecta", new proj(_))   val projb = project("projb", "projectb", new proj(_))    val akkarepo = "akka maven2 repo" @ "http://www.scalablesolutions.se/akka/repository/"   val multiversrepo = "multiverse maven2 repo" @ "http://multiverse.googlecode.com/svn/maven-repository/releases/"   val guiceyfruitrepo = "guiceyfruit maven2 repo" @ "http://guiceyfruit.googlecode.com/svn/repo/releases/"   val jbossrepo = "jboss maven2 repo" @ "https://repository.jboss.org/nexus/content/groups/public/"    class proj(info:projectinfo) extends defaultproject(info){     val junit = "junit" % "junit" % "4.5" % "test"     val scalatest = "org.scalatest" % "scalatest" % "1.2" % "test"     val akka = "se.scalablesolutions.akka" % "akka-core_2.8.0" % "0.10"   } }

edit: should point out there better way use akka, illustrating point.

use inheritance , mixins:

import sbt._  class modularproject(info: projectinfo) extends defaultproject(info){      lazy val childproject = project("proja", "projecta",          new defaultproject(_)                repositories              globaldependencies             akkadependencies)      trait repositories{         lazy val akkarepo = "akka maven2 repo" @          "http://www.scalablesolutions.se/akka/repository/"         lazy val multiversrepo = "multiverse maven2 repo" @          "http://multiverse.googlecode.com/svn/maven-repository/releases/"         lazy val guiceyfruitrepo = "guiceyfruit maven2 repo" @          "http://guiceyfruit.googlecode.com/svn/repo/releases/"         lazy val jbossrepo = "jboss maven2 repo" @          "https://repository.jboss.org/nexus/content/groups/public/"     }      trait globaldependencies{         lazy val junit = "junit" % "junit" % "4.5" % "test"         lazy val scalatest = "org.scalatest" % "scalatest" % "1.2" % "test"     }      trait akkadependencies{         lazy val akka = "se.scalablesolutions.akka" % "akka-core_2.8.0" % "0.10"     }         }
