programatic scaladoc access via sbt

[Joe Betz]

I'm trying to integrate a sbt plugin that makes use of scala's programmatic scaladoc access.  I've been able to use the scaladoc programmatic access in gradle just fine, but in SBT I'm hitting a error in the nsc compiler.  I've reduced it down to a few simple steps.

How to replicate:

Take a simple play sbt project using 0.13.0

$ cd <some temp dir>
$ mkdir project
$ echo "sbt.version=0.13.0" > project/build.properties
$ sbt
$ console
import tools.nsc.doc.{DocFactory, Settings}
import tools.nsc.reporters.ConsoleReporter
val settings = new Settings(error => print(error))
settings.usejavacp.value = true
val reporter = new ConsoleReporter(settings)
val docFactory = new DocFactory(reporter, settings)
val filelist = List()
val universe = docFactory.makeUniverse(Left(filelist))

adding dependencies does not help, e.g.: build.sbt

name := "hello"

version := "1.0"

scalaVersion := "2.10.3"

libraryDependencies += "org.scala-lang" % "scala-reflect" % "2.10.3"

libraryDependencies += "org.scala-lang" % "scala-library" % "2.10.3"

libraryDependencies += "org.scala-lang" % "scala-compiler" % "2.10.3"

Nor does adding the scala reflect/library/compiler dependencies project/plugins.sbt.

> show all-dependencies
[info] List(org.scala-lang:scala-compiler:2.10.3:scala-tool->default,optional(default), org.scala-lang:scala-library:2.10.3:scala-tool->default,optional(default), org.scala-lang:scala-library:2.10.3, org.scala-lang:scala-reflect:2.10.3, org.scala-lang:scala-library:2.10.3, org.scala-lang:scala-compiler:2.10.3) 

Any ideas what I may have overlooked?

Thanks!

Take a look at embeddedDefaults, described http://www.scala-sbt.org/release/docs/Howto/scala.html

Thanks for the pointer Jason.  That helps.
