What's wrong with Groovy multi-line String?

Question

Groovy scripts raises an error:

def a = \"test\"
  + \"test\"
  + \"test\"

Error:

No signature of method: java.lang.String.         


        

Answer 1

You can tell Groovy that the statement should evaluate past the line ending by adding a pair of parentheses ( ... )

def a = ("test"
  + "test"
  + "test")

A second option is to use a backslash, \, at the end of each line:

def a = "test" \
  + "test" \
  + "test"

FWIW, this is identical to how Python multi-line statements work.
