How to determine what dependency is forcing the scala version to be 2.10 when scalaVersion is set to 2.11.2

I'm trying to build the lunatech-securesocial-poc project with scala 2.11.2 and I've updated the scalaVersion in projects/Build.scala. This project depends on securesocial, which I've built locally with 2.11.2 and named its artifact version master-SNAPSHOT. I've updated the dependency in lunatech-securesocial-poc's project to use this version of securesocial. However, SBT (activator) fails to compile because it is looking for ws.securesocial#securesocial_2.10;master-SNAPSHOT. How can I find out what is causing the scala version to be overridden to 2.10. I want 2.11.2. Obviously some dependency is forcing it, but I want to find out what that dependency is, and fix it.

I've tried adding:

dependencyOverrides += "org.scala-lang" % "scala-library" % scalaVersion.value

evictionWarningOptions := EvictionWarningOptions.default.withWarnTransitiveEvictions(true).withWarnDirectEvictions(true).withWarnScalaVersionEviction(true) ivyScala := ivyScala.value map { _.copy(overrideScalaVersion = true) }

to my Build.scala and I'm using SBT version 0.13.7. I don't see why it is so hard for SBT to just abort and tell me that XXX dependency is preventing it from using 2.11.2 and requiring 2.10.

Anyone?

What does your Build.scala look like right now? – Michael Zajac
Here is my build.scala: pastebin.com/07CJwkKr – eswenson
Turned out it was a silly mistake in my Build.scala. While I defined scalaVersion in the object (ApplicationBuild) that extends Build, and used it in some dependencies, I failed to include the setting of scalaVersion in the Project settings list. – eswenson

You can use sbt-dependency-graph plugin to find this out.

The issue turned out to be in my Build.scala. While I defined scalaVersion and used it in setting up dependencies, I didn't pass a setting to the Project that overrode the default scalaVersion, which evidently is the one used to build activator (2.10.4). So despite thinking I had set scalaVersion, I hadn't really.
