I am using sbt assembly to try and take our application and create 'one big jar' to deploy it.
I am having a problem where Play 2.1.2 depends on scala-stm 0.6 and akka-transactor 2.1.4 depends on scala-stm 0.7.
I am able to run the app in SBT without issue (as well as Eclipse and IntelliJ)
I am unclear how to resolve this issue using 'sbt assembly'
Here is some output explaining exactly what I am seeing (snipped some stuff):

If I look at the dependency tree I see the two things that have the conflicting dependencies (trimmed a bunch of stuff out):

Any suggestions on how to go about resolving this dependency issue?
========================= EDIT: addition of simpler example =======================
I decided to try and create a very simple application with just Play and Akka. However, I got as far as trying to 'assembly' a simple Play app and am having problems.
Here is my project/plugins.sbt file:
resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.9.1")
addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.7.4")
addSbtPlugin("play" % "sbt-plugin" % "2.1.0")
Here is my project/Build.scala file:
import sbt._
import Keys._
import play.Project._
import sbtassembly.Plugin._
import AssemblyKeys._
object ApplicationBuild extends Build {
val appName = "dependencyExample"
val appVersion = "1.0"
val appDependencies = Nil
val appSettings = Defaults.defaultSettings ++ assemblySettings ++ Seq(net.virtualvoid.sbt.graph.Plugin.graphSettings:_*)
val main = play.Project( appName, appVersion, appDependencies, settings = appSettings)
}
And here is the output I get from 'assembly'
[dependencyExample] $ assembly

It is still not clear to me how I can resolve this issue. I suspect if I can resolve this simple test issue then I can resolve the Akka + Play issue.
=================== EDIT: different way of accomplishing the same thing =================
I found a 'magical' sbt command with play. 'dist'. This packages up the application in a .zip file and can then be extracted and run on any machine that has java installed.
Here is the blog post at coursera that we found the tidbit on:
