Question

if i define a groovy variable

def x = "anish$"

it will throw me error, the fix is

def x = "anish\$"

apart form “$” what are the blacklist characters that needs to be backslash,Is there a Groovy reference that lists the reserved characters. Most “language specifications” mention these details, but I don’t see it in the Groovy language spec (many “TODO” comments).

Answer 1

Just use single quotes:

def x = 'anish$'

If this isn’t possible, the only thing that’s going to cause you problems is $, as that is the templating char used by GString (see the GString section on this page — about half way down)

Obviously, the backslash char needs escaping as well, ie:

def x = 'anish\\'
