This plugin concats multiple resource files to one.
Add the dependency in your project's plugins.sbt file:
resolvers += Resolver.url("ssachtleben sbt repository (snapshots)", url("http://ssachtleben.github.io/sbt-plugins/repository/snapshots/"))(Resolver.ivyStylePatterns)
addSbtPlugin("com.ssachtleben.sbt" % "sbt-assets-concat" % "1.0.0")
