Parser and Lexer Files Not Auto Generated by Eclipse

Question

I'm using the antlr-3.4-complete-no-antlrv2.jar version of ANTLR on Eclipse Indigo.

I have installed the ANTLR IDE plugin along with ZEST and GEF. When I generate a combined grammar file and add a header, lexer header and a rule, Eclipse doesn't generate the Parser and Lexer files.

If I use antlr-3.2.jar it does. I can generate the Lexer and Parser files (using antlr-3.4.*) outside of Eclipse using java -classpath antlr-3.4-complete-no-antlrv2.jar org.antlr.Tool Sample.g.

Is there any way to turn this on in Eclipse for version 3.4 ?

See this thread on SourceForge

You can't use the no antlrv2 version.

That may or may not fix the problem, I have everything set up correctly but as others have found and reported on SourceForge it simply won't output any Java.
