title: Parser and Lexer Files Not Auto Generated by Eclipse
body: <p>I'm using the antlr-3.4-complete-no-antlrv2.jar version of ANTLR on Eclipse Indigo.  </p>
  
  <p>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. </p>
  
  <p>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 <strong><em>java -classpath antlr-3.4-complete-no-antlrv2.jar org.antlr.Tool Sample.g</em></strong>.  </p>
  
  <p>Is there any way to turn this on in Eclipse for version 3.4 ?</p>
