我正在使用本教程在我的播放框架应用程序中上传文件。我正在使用完全相同的代码，但出现以下错误。
[IOException: Path(/Users/hrishikeshparanjape/Desktop) exists but replace parameter is false]
以下是我的代码：
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"
)
}
}
我被困在这里请帮忙。
编辑： 这是我的完整堆栈跟踪：
