scala – 在sbt 0.11中的自定义任务中获取项目的源文件

发布时间：2020-12-16 09:57:22 所属栏目：安全来源：网络整理

导读：我用SBT 0.11. 我在sbt项目中有以下build.sbt文件： myAction := { // val srcFiles = ? // How can I make srcFiles a List[File] of all sources files? println("This is my action")} 它工作正常,但我怎么能访问所有Java / Scala源文件路径的设置,例如sr

我用SBT 0.11.

我在sbt项目中有以下build.sbt文件：

myAction := {
  // val srcFiles = ?
  // How can I make srcFiles a List[File] of all sources files?
  println("This is my action")
}

它工作正常,但我怎么能访问所有Java / Scala源文件路径的设置,例如src / main / scala / * .scala,以及目标类目录,例如目标/斯卡拉-2.9.1 /班？

解决方法

比如定义一个taskKey

yourActionTask

然后

yourActionTask <<= (baseDirectory,target,packageBin in Compile,resources in Compile...) map { (basedir,targetDir,bin,res...)=>  
     // use these resources to complete your task as per your needs
}

BTW.您可以在Keys.scala源代码或sbt的scaladoc中找到更多预定义的任务/密钥.

这里有一个例子,你可以参考我从我的一个构建文件中提取的(只是将TaskKey和Task定义结合在一起,因为我不打扰我将来会重用TaskKey)：

val distTask = TaskKey[Unit]("dist","distribute the deployment package of eromanga") <<= (baseDirectory,fullClasspath in Compile,resources in Compile,streams) map {
(baseDir,cp,jar,res,s) =>
  s.log.info("[dist] prepare distribution folders...")
  val assemblyDir = targetDir / "dist"
  val confDir = assemblyDir / "conf"
  val libDir = assemblyDir / "lib"
  val binDir = assemblyDir / "bin"
  Array(assemblyDir,confDir,libDir,binDir).foreach(IO.createDirectory)

  s.log.info("[dist] copy jar artifact to lib...")
  IO.copyFile(jar,libDir / jar.name)

  s.log.info("[dist] copy 3rd party dependencies to lib...")
  cp.files.foreach(f => if (f.isFile) IO.copyFile(f,libDir / f.name))

  s.log.info("[dist] copy shell scripts to bin...")
  ((baseDir / "bin") ** "*.sh").get.foreach(f => IO.copyFile(f,binDir / f.name))

  s.log.info("[dist] copy configuration templates to conf...")
  ((baseDir / "conf") * "*.xml").get.foreach(f => IO.copyFile(f,confDir / f.name))

  s.log.info("[dist] copy examples chanenl deployment...")
  IO.copyDirectory(baseDir / "examples",assemblyDir / "examples")

  res.filter(_.name.startsWith("logback")).foreach(f => IO.copyFile(f,assemblyDir / f.name))
  }
