Scala Question

Sbt-assembly unresolved dependency, Scala

I'm installing Sbt-Assembly, but am now stuck.

Sbt Version (from 'sbt about'): 0.13.8
Current project is built against scala 2.11.6
Sbt, sbt plugins, and build definitions are using Scala 2.10.4


project/assembly.sbt



addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.0")
resolvers += Resolver.url("bintray-sbt-plugins", url("http://dl.bintray.com/sbt/sbt-plugin-releases"))(Resolver.ivyStylePatterns)


build.sbt



scalaVersion in ThisBuild := "2.11.6"


~/.sbt/0.13/global.sbt



scalaVersion := "2.11.6"


I realize sbt-assembly is for scala 2.10. If I change my project to scala 2.10, I have new unavailable dependencies for 2.10 which is not desirable. Is there a way to configure my project to use 2.10 just for the assembly plugin?

==== bintray-sbt-plugins: tried

Note: Some unresolved dependencies have extra attributes.
Check that these dependencies exist with the requested attributes.

com.eed3si9n:sbt-assembly:0.14.0 (scalaVersion=2.11, sbtVersion=0.13)

Answer

Just remove scalaVersion from global.sbt.

Because SBT is recursive it uses this scalaVersion from global.sbt when building your build files, which fails because SBT 0.13 is built with Scala 2.10, and so are all SBT plugins.
