Delete directory recursively in Scala

Using scala IO

import scalax.file.Path

val path = Path.fromString("/tmp/testfile")    
try {
  path.deleteRecursively(continueOnFailure = false) 
} catch {
  case e: IOException => // some file could not be deleted
}

or better, you could use a Try

val path: Path = Path ("/tmp/file")
Try(path.deleteRecursively(continueOnFailure = false))

which will either result in a Success[Int] containing the number of files deleted, or a Failure[IOException].

Try this code that throws an exception if it fails:

def deleteRecursively(file: File): Unit = {
  if (file.isDirectory) {
    file.listFiles.foreach(deleteRecursively)
  }
  if (file.exists && !file.delete) {
    throw new Exception(s"Unable to delete ${file.getAbsolutePath}")
  }
}

You could also fold or map over the delete if you want to return a value for all the deletes.

With pure scala + java way

import scala.reflect.io.Directory
import java.io.File

val directory = new Directory(new File("/sampleDirectory"))
directory.deleteRecursively()

deleteRecursively() Returns false on failure
