Subject ANTLR task doesn't update its output
Date Fri, 25 Jun 2004 22:07:10 GMT
Hi,

I've got the following ANTLR in my build.xml:

     <antlr target="${parser.dir}/KIFParser.g">
       <classpath>
	<pathelement location="lib/antlr.jar"/>
       </classpath>
     </antlr>

The transcript below starts at a state where everything has been 
compiled. Note that when I touch KIFParser.g and call ant again, ANTLR 
is re-invoked. But the output files are not updated. Futher invocations 
of ant again invoke ANTLR. Hoping I've made an error as silly as the 
last one I had posted?

Again, I'm using ant 1.6.1 on mac os x.

Thanks!

Sunil
