[antlr-interest] Antlr3 in Eclipse and Maven?

[Brad Cox]

Thanks! The new version number did the trick. The wiki instructions are
just broken.

And I still don't have a solution to why the grammar statement still isn't
recognized.

That revealed a problem I've seen all along in the generated lexer code...
the _type variable is never declared. Accepting the eclipse quick fix
(declare local variable) clears the problem. But the code generator should
have done this without having to repair it by hand.
