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.

The main part in that link to focus on is "To enable ANTLR support for the project, in the Package Explorer window (left pane) right-click the project just created and select Configure, Convert to ANTLR project.". That fixed it for me. – Flaring
