Answer 1

def resultString="Hello word result Hello: 0 Word: 0 void: 0" println(resultString.replaceAll("\\s","\\\\\\\\"))

Answer 2

https://docs.oracle.com/javase/8/docs/api/java/lang/String.html#replaceAll-java.lang.String-java.lang.String-
replaceAll uses Regex Matching, which changes the behaviour of the escaping

use replace instead:

def resultString="Hello word result Hello: 0 Word: 0 void: 0"
def resultString1=resultString.replace(' ','\\\\')
println resultString1

output:

Hello\\word\\result\\Hello:\\0\\Word:\\0\\void:\\0
