Description ow 2003-05-18 15:40:57 UTC 
AFAIK, "-traceTreeParser" is the valid option now.

--------------------------------------------------------------

ANTLR Parser Generator   Version 2.7.2   1989-2003 jGuru.com
warning: invalid command-line argument: -traceTreeWalker; ignored

---> ANTLR.java 
 ....
    private void populateAttributes() {
	....   

        if (traceTreeWalker) {
// here, I think
            commandline.createArgument().setValue("-traceTreeWalker");
        }
        if (debug) {
            commandline.createArgument().setValue("-debug");
        }
    }

Do you know of an easiliy accessible way for Ant to determine whether it is running
version 2.7.2 (or later) or 2.7.0?

In 2.7.0 the option is documented as -traceTreeWalker.
Comment 2 ow 2003-05-19 16:54:02 UTC 
antlr.Version class appears to have all the info you may need.
Comment 3 Stefan Bodewig 2003-05-21 13:14:58 UTC 
You are right.  The best thing about antlr.Version is that it didn't exist in 2.7.0
so we only need to check for its existance.

fixed in nightly build 2003-05-22.
