创建SBT任务以在编译期间复制目录？

import sbt._

object CopyDirectoryTask extends AutoPlugin {
  override def trigger = allRequirements

  object autoImport {
    val copyDirectory = taskKey[Unit]("Copies a directory during compilation")
  }

  import autoImport._

  override lazy val projectSettings = Seq(
    copyDirectory := {
      val sourceDir = file("source-directory")
      val targetDir = file("target-directory")
      IO.copyDirectory(sourceDir, targetDir)
    }
  )
}

lazy val root = (project in file("."))
  .enablePlugins(CopyDirectoryTask)
  .settings(
    name := "MyProject",
    version := "1.0",
    scalaVersion := "2.13.6"
  )
