I've just tested this with the following config:
- no CLASSPATH
- antlr-2.7.5.jar
- Ant 1.6.5 - works with line break
- Ant svn trunk - works with line break
both on Java1.6-rc Windows XP SP2
attached build file and test grammar
build.xml

class P extends Parser;
startRule
: n:NAME
{System.out.println("Hi there, "+n.getText());}
;
class L
extends Lexer; //broken across lines to test ant task
// one-or-more letters followed by a newline
NAME: ( 'a'..'z'|'A'..'Z' )+ NEWLINE
;
NEWLINE
: '\r' '\n' // DOS
| '\n' // UNIX
;
As I can't see where in the ANTLR task we could possibly be breaking and causing
this issue, and as it works under test conditions (albeit a simple test), I'm
going to close this - please REOPEN if you can provide a test grammar + build
file where this fails for you - my guess is that this was fixed a long time ago
and was never closed.
Thanks for teh report
