scala - 为什么 sbt compile 不会将非托管资源复制到类路径？

Question

你能告诉我为什么sbt compile不将非托管资源复制到类路径？另一方面sbt package做。因此，除非我调用 package，否则我无法开始调试手动调用:(

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
}

resolvers ++= Seq(
  "spray repo" at "http://repo.spray.io/"
)

libraryDependencies ++= {
  val sprayVersion = "1.2-M8"
  val akkaVersion  = "2.2.0-RC1"
Seq(
  "io.spray"            %   "spray-servlet" % sprayVersion withSources(),

)
}

compile的工作是编译源，所以它通常不会做任何与处理资源相关的事情。但是，资源需要在 run 的类目录中。 , package , test , console ，以及任何其他使用 fullClasspath 的内容.这是由 fullClasspath 完成的合并 exportedProducts ，是当前项目生成的类和资源，dependencyClasspath ，它们是来自依赖项的类路径条目。

适当的解决方案取决于需要什么资源。从命令行运行 exported-products做一个compile以及 copy-resources .以编程方式，您通常希望依赖 fullClasspath或 exportedProducts .

作为旁注，您通常可以使用 the inspect command 找出任务的作用。 .
