title: Why does sbt give multiple dependencies warning with Akka and ScalaTest dependencies?
body: <p>I've just added ScalaTest to <code>build.sbt</code> so it now looks as follows:</p>
  
  <pre><code>name := "appname"
  
  version := "1.0"
  
  scalaVersion := "2.11.7"
  
  libraryDependencies ++= Seq(
    "com.typesafe.akka" %% "akka-actor" % "2.4.1",
    "org.scalatest" % "scalatest_2.11" % "2.2.4" % "test"
  )
  </code></pre>
  
  <p>After that I am receiving the warning message:</p>
  
  <pre><code>SBT project import
           [warn] Multiple dependencies with the same organization/name but different versions. To avoid conflict, pick one version:
           [warn]  * org.scala-lang:scala-reflect:(2.11.2, 2.11.7)
           [warn]  * org.scala-lang.modules:scala-xml_2.11:(1.0.2, 1.0.4)
  </code></pre>
  
  <p>I also tried changing the line concerning ScalaTest into:</p>
  
  <pre><code>"org.scalatest" %% "scalatest" % "2.2.4" % "test"
  </code></pre>
  
  <p>but the warning still remains the same as above.</p>
  
  <p>How could I deal with this issue since I haven't anywhere written "reflect" or "xml" in my project. I am using the newest version of both Akka and ScalaTest and Scala version 2.11.</p>
