I get the following error when I do a ./sbt assembly on my Scala project. I saw the first after adding these dependencies to my build.sbt I can compile and run my code.
libraryDependencies ++= Seq(
"org.scalanlp" % "breeze_2.10" % "0.7",
"org.scalanlp" % "breeze-natives_2.10" % "0.7"
)

I use this in my build.sbt:
excludedJars in assembly <<= (fullClasspath in assembly) map { cp =>
cp filter {x => x.data.getName.matches("sbt.*") || x.data.getName.matches(".*macros.*")}
}
