Question

This piece of scala code:

val file = new File(".")
assert(file.exists == true)
assert(file.getAbsolutePath.length > 0)
println(scala.io.Source.fromFile(file).getLines)

Throws:

FileNotFoundException: . (No such file or directory) (FileInputStream.java:120)

While making the scala.io.Source.fromFile call. How is this possible and how can I fix it?

PS: This is in the context of a playframework app test.

Answer 1

Maybe because:

assert(file.isDirectory)

passes as well? You cannot really open a directory and read it, you can only open files. BTW on my machine the error is more descriptive:

java.io.FileNotFoundException: . (Is a directory)

Tested on:

$ java -version
java version "1.6.0_26"
$ scala -version
Scala code runner version 2.9.1.final
