remove_comment_regex.txt

Remove all block comments and line comments:
(/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/|[ \t]*//.*)

Remove block comments:
(/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/)

Remove line comments:
([ \t]*//.*)


However, I should warn that this works only %99.99 of time. You might have a string variable defined in your file like:
String myStr = "/** I am not a comment */";
This regex will turn this to:
String myStr = "";

Nice, thanks!

Awesome, mate. Works like a charm. Just regex replace and... Voiláa. No need for specific software or anything else. Thanks.
