Resolving the dependency of Scala Macros and Compiler Framework in SBT - scala

Question

I am trying to write a framework to make writing Scala compiler plugins easier, what I am doing is writing a framework on top of the Scala quasiquotes. So my project depends on macros from macro-paradise and both scala-compiler and scala-reflect libraries.
I wrote an SBT build script by following the instructions mentioned here: https://github.com/scalamacros/sbt-example-paradise/blob/master/project/Build.scala
And used scalaVersion 2.11.0-SNAPSHOT, 2.10.3-SNAPSHOT, 2.10.3-RC1, 2.10.2 to compile my project, but neither of them worked. Here is my sbt build script:
import sbt._
import Keys._
object LombrelloBuildSettings {
val sversion = "2.10.3-SNAPSHOT"
val buildSettings = Defaults.defaultSettings ++ Seq(
name := "lombrello",
organization := "ch.usi.inf.l3",
version := "0.1-SNAPSHOT",
scalacOptions ++= Seq("-unchecked", "-deprecation", "-feature"),
scalaVersion := sversion,
scalaOrganization := "org.scala-lang.macro-paradise",
resolvers += Resolver.sonatypeRepo("snapshots"),
licenses := ("BSD 3-Clause", new java.net.URL("http://opensource.org/licenses/BSD-3-Clause")) :: Nil,
libraryDependencies ++= Seq("org.scala-lang.macro-paradise" % "scala-reflect" % sversion,
"org.scala-lang" % "scala-compiler" % sversion),
addCompilerPlugin("org.scala-lang.plugins" % "macro-paradise" % "2.0.0-SNAPSHOT" cross CrossVersion.full))
}
object LombrelloBuild extends Build {
import LombrelloBuildSettings._
lazy val root: Project = Project(
"root",
file("."),
settings = buildSettings ++ Seq(
run <<= run in Compile in tests
)
) aggregate (main, tests)
lazy val main: Project = Project(
"main",
file("src/main"),
settings = buildSettings
)
lazy val tests: Project = Project(
"tests",
file("src/test"),
settings = buildSettings ++ Seq(name := "tests")) dependsOn (main)
}
Using the scalaVersion 2.10-3-RC1, I get the following error:

Using, scalaVersion 2.11.0-SNAPSHOT, I got the following error:
java.lang.NoClassDefFoundError: scala/tools/nsc/typechecker/TypersTracking$class

While using the version 2.10.3-SNAPSHOT I got the following:
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[warn] :: UNRESOLVED DEPENDENCIES ::
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[warn] :: org.scala-lang.plugins#macro-paradise_2.10.3-SNAPSHOT;2.0.0-SNAPSHOT: not found
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
sbt.ResolveException: unresolved dependency: org.scala-lang.plugins#macro-paradise_2.10.3-SNAPSHOT;2.0.0-SNAPSHOT: not found
And version 2.10.2 couldn't resolve the dependencies of scala-library, scala-reflect and 2.10.2 at all (like 2.10.3-RC1)!
My question is, is it at all possible to mix both compiler API and Macro API and make them work under SBT, if yes what exactly is wrong with my build script?

Answer 1

It appeared that I used some wrong settings in my SBT configuration. I didn't need to change the scalaOrganization, neither needed to add macro-paradise to my library dependencies. so the settings should become like:
val sversion = "2.10.2"
val buildSettings = Defaults.defaultSettings ++ Seq(
name := "lombrello",
organization := "ch.usi.inf.l3",
version := "0.1-SNAPSHOT",
scalacOptions ++= Seq("-unchecked", "-deprecation", "-feature"),
scalaVersion := sversion,
resolvers += Resolver.sonatypeRepo("snapshots"),
licenses := ("BSD 3-Clause", new java.net.URL("http://opensource.org/licenses/BSD-3-Clause")) :: Nil,
libraryDependencies ++= Seq("org.scala-lang" % "scala-reflect" % sversion,
"org.scala-lang" % "scala-compiler" % sversion),
addCompilerPlugin("org.scala-lang.plugins" % "macro-paradise" % "2.0.0-SNAPSHOT" cross CrossVersion.full)
)
