I know there is scalacOptions in sbt. But options add via addCompilerPlugin does not exists in scalacOptions.

I type show scalacOptions in sbt console and there is nothing like -Xplugin.

So how can I get real scalac options when I am writing an sbt plugin

My sbt info

> libraryDependencies
[info] List(org.scala-lang:scala-library:2.10.4, org.scala-lang:scala-reflect:2.10.4, io.netty:netty:3.9.0.Final, net.sandrogrzicic:scalabuff-runtime:1.3.7, org.scalamacros:quasiquotes:2.0.0, org.specs2:specs2:2.3.11:test, org.scalamacros:paradise:2.0.0:plugin->default(compile))

I glad to see that I'm not the only one who get bunch of troubles with sbt. It just have no documentation, so make git clone of the project and try to track source code inside ./main/src/main/scala/sbt/Defaults.scala – ayvango

Finally I found compile:scalacOptions actually contains the plugin settings

Are you sure that you have actually managed to add the compiler plugin?

With sbt 0.13.5 and an empty project with this in build.sbt:

addCompilerPlugin("org.scala-lang.plugins" % "continuations" % "2.10.1")

I get the plugin in both libraryDependencies and scalacOptions:
