reg ex expression, just need to split on comma

Test code here. I want to augment my current regex to split on commas

String test = "This Is ,A Test"
println(test)
String noSpace = test.replaceAll("\\s","")
println(noSpace)
String[] words = noSpace.split("[^a-zA-Z0-9'-.]+")

words.each {
   println(it)
}

This produces the output 

This Is ,A Test
ThisIs,ATest
ThisIs,ATest

Where I want it to produce the output

This Is ,A Test
ThisIs,ATest
ThisIs
ATest

Any thoughts? Thanks!

Cite from javadoc

Note that a different set of metacharacters are in effect inside a character class than outside a character class. For instance, the regular expression . loses its special meaning inside a character class, while the expression - becomes a range forming metacharacter.

So you need to escape the dash:

String[] words = noSpace.split("[^a-zA-Z0-9'\\-.]+");

To split based on comma, simply use 

String[] words = noSpace.split(",");
