Changing working directory in Scala

Question

I am working with Scala in Eclipse IDE on a Windows machine.

I am trying to get a list of files from a specific directory:

    val filesHere = (new java.io.File(".")).listFiles

This provides the file names of all the files in the default directory which is D:\Scala\eclipse. This is confirmed by the following command:

    System.getProperty("user.dir")                  
    > res23: String = D:\Scala\eclipse

I tried changing the directory to a different location with the following command (Based on suggestions from here)

    System.setProperty("user.dir","D:/Scala/")

Looks like the user directory is changed as confirmed by the following command:

    System.getProperty("user.dir")                  
    > res25: String = D:/Scala/

However, the following command list the files from the default directory and not the new directory:

    val filesHere = (new java.io.File(".")).listFiles

Could someone explain how to make it point to the new directory?

Thanks, this works great. However, this lists the files along with the complete path...is there a way to get only the name of the file without the complete path? — Ravi, Jun 25 '14 at 13:49
It returns new `File` objects actually, get the file name without path with `getName`. — wingedsubmariner, Jun 25 '14 at 13:53
I tried this val fileList = (new java.io.File("D:/Scala/")).getName but this only returns fileList : String = Scala and doesn't return all the file names — Ravi, Jun 25 '14 at 13:58
No, do `new java.io.File("D:/Scala/").listFiles.map(_.getName)` — wingedsubmariner, Jun 25 '14 at 13:58
