mahout-math-scala 0.9 binding gives NoClassDefFoundError:
scala/reflect/ClassManifest using Scala 2.10.2
I have included Mahout 0.9 libraries with Scala 2.10.2 in my project's
build.sbt as follows:
scalaVersion :="2.10.2"
libraryDependencies += "org.apache.mahout" % "mahout-core" % "0.9"
libraryDependencies += "org.apache.mahout" % "mahout-math" % "0.9"
libraryDependencies += "org.apache.mahout" % "mahout-examples" % "0.9"
libraryDependencies += "org.apache.mahout" % "mahout-math-scala" % "0.9"
libraryDependencies += "org.scala-lang" % "scala-library" % "2.10.2"
libraryDependencies += "org.scala-lang" % "scala-reflect" % "2.10.2"
When I try to use mahout-math-scala bindings described here [1] from
SBT console, I get following:
$ sbt console
Welcome to Scala version 2.10.2 (OpenJDK 64-Bit Server VM, Java 1.7.0_51).

Note that I have included both "scala-library" and "scala-reflect"

What am I doing wrong? Please suggest.

Hi Dmitriy,
I switched to Scala 2.9.3. It works for me now.
Thanks,
