[antlr-interest] errors in embedding grammar files in maven project - regd.

[Jared Bunting]

I guess I'm a bit confused about the issue you're having then.  Between
having the package statement "package dot.grammar" and having your source
code in a "dot/grammar" folder structure, your classes should be in the
package.  Do you actually have folders named "dot.grammar" ?  But basically,
whatever directory you want the output source to be in (underneath
"target/generated-sources/antlr"), put it in that directory underneath
"src/main/antlr".

If this doesn't help, maybe you could zip up a project and send it to me?
I'm pretty sure I do what you're trying to do fairly often and I haven't had
any trouble with it.
