scala – 为什么sbt编译不会将非托管资源复制到类路径？

我正在使用SBT 0.12.1

下面是我的build.sbt.

import AssemblyKeys._ // put this at the top of the file

net.virtualvoid.sbt.graph.Plugin.graphSettings

assemblySettings

organization  := "com.zzz"

version       := "0.1"

scalaVersion  := "2.10.2"

scalacOptions := Seq("-unchecked","-language:reflectiveCalls,postfixOps,implicitConversions","-deprecation","-feature","-encoding","utf8")

unmanagedResourceDirectories in Compile <++= baseDirectory { base =>
    Seq( base / "src/main/webapp" )
}

jarName in assembly := "zzz.jar"

mergeStrategy in assembly <<= (mergeStrategy in assembly) { (old) =>
    {
        case "rootdoc.txt" => MergeStrategy.discard
        case x => old(x)
    }
}

mainClass in assembly := Some("com.zzz.Boot")

name := "zzz"

// disable using the Scala version in output paths and artifacts
crossPaths := false

artifactName := { (sv: ScalaVersion,module: ModuleID,artifact: Artifact) =>
  artifact.name + "." + artifact.extension
}
