My preference is to use File (or Path) object whenever dealing with files – and then ONLY using forward slashes.  So for your request:

def scriptDir = /C:\Folder1\My Documents\Folder2\Version\etc\/


def scriptDir = new File("C:/Folder1/My Documents/Folder2/Version/etc")

or (if you really wanted the path as a string)

def scriptDir = new File("C:/Folder1/My Documents/Folder2/Version/etc").absolutePath


I agree that copy-pasting file paths from File Explorer and then twiddling the slash direction is a bit tedious – but better than figuring out all that escaping!  I dare say that using a File object has overheads – but at least you can test if the file or directory exists. Iterate over the files etc. etc.


Adding pieces of a path or path and file name together, again use the File class:


def myScript = new File("C:/Folder1/My Scripts", "Script1.groovy")

def myScript = new File(scriptDir, "Script1.groovy")


It saves getting the['file.separator'] – and you can even ignore the drive letter (if it is on the current disk).

def myScript = new File("/Folder1/My Scripts", "Script1.groovy")


And yes – I use groovy rather a lot on Windows.

Also be careful when using slashy Strings with path names that start with a lowercase "u" 


They'll get interpreted as a unicode character escape, e.g. /c:\users/ --> TokenStreamIOException: Did not find four digit hex character code.


(BTW, I'm glad to see there are other GroovyConsole users on Windows out there)

Long time ago I was using slashy strings in my groovy scripts for the paths on Windows. Somehting like this:

def scriptDir = /C:\Folder1\My Documents\Folder2\Version\etc\/


However in the recent versions, like 2.3.6 or 2.4.11, I can no longer execute those scripts via a GroovyConsole. It always gave me an error pointing to the last charecter of the script. Like this:

unexpected char: 0xFFFF at line: 19, column: 13

which was a bit misleading...


When I change the paths to a "normal" srtings, everything works fine, as it was before.

def scriptDir = "C:\\Folder1\\My Documents\\Folder2\\Version\\etc\\"


Is it a bug? Shall I report it?
