[antlr-interest] No lexer generated

[Juancarlo Añez]

I have a grammar that starts like this:

grammar COBOL;
options {
    language  = Python;
    backtrack = false;
    output    = AST;
    ASTLabelType=CommonTree;
}

import Tokens, Lexical;


And no lexer or code for Tokens or Lexical is generated.

I have the exact same setup for another grammar, and it works.

What can be happening this time?
