Scala递归删除某个文件夹

//check the result is already exists or not
val outFilePath = "D:/doc/spark/out/t2"
val outFile = new File(outFilePath)

//recursion delete
def deleteFileMethod(filePath:File): Unit ={
  if(filePath.isDirectory){
    val fileList = filePath.listFiles()

    for(i <- fileList){
      if(i.isDirectory){
        deleteFileMethod(i)
      }else{
        i.delete()
        println("delete file : "+i)
      }

    }
  }else{
    filePath.delete()
  }
  
  //just to delete the most outer dir
  outFile.delete()
}
deleteFileMethod(outFile)
