[antlr-interest] expecting IDENT, found 'x'

It's because the lexer and parser are not using the same token vocabulary.
Note that the the two files ending in .txt list a different set of tokens.
I was able to fix your problem by putting "exportVocab=Test;" in the parser
options and changing the lexer options to read "importVocab=Test;".

A question for those more experienced, in what senario would you want the
lexer and parser using different vocabularies?  If there aren't any such
senarios, would it be better if ANTLR took care of making sure both are
using the same vocabulary instead of relying on the user to do this?  I
stumbled over the same vocabulary issue myself while learning the basics of
ANTLR.
