You most likely have a conflict with SLF4J from one of your other plugins. I know of the following 2 that cause this problem:

libraryDependencies += "net.databinder.giter8" % "giter8-lib_2.10" % "0.6.8" exclude("org.slf4j", "slf4j-jdk14")

addSbtPlugin("org.xerial.sbt" % "sbt-pack" % "0.7.9" exclude("org.slf4j", "slf4j-simple"))

The exclude clause solves the problem.
