scala play framework Dateiupload Fehler

Question

Ich benutze this Tutorial, um eine Datei in meine Play-Framework-Anwendung hochzuladen. Ich benutze den exakt gleichen Code, aber ich bekomme folgenden Fehler.

[IOException: Path(/Users/hrishikeshparanjape/Desktop) exists but replace parameter is false] 

Folgende ist mein Code:

def upload = Action(parse.multipartFormData) { request => 
     request.body.file("picture").map { picture => 
      import java.io.File 
      val filename = picture.filename 
      val contentType = picture.contentType 
      picture.ref.moveTo(new File("/Users/hrishikeshparanjape/Desktop/")) 
      Ok("File uploaded") 
     }.getOrElse { 
      Redirect(routes.Application.index).flashing(
        "error" -> "Missing file" 
        ) 
     } 
    } 

Ich stecke hier bitte helfen.

Sehen aus wie Sie die vollständigen Dateinamen angeben müssen für moveTo

picture.ref.moveTo(new File(
    "/Users/hrishikeshparanjape/Desktop/" + picture.filename))
