Hi all,
(I couldn't find an issue tracker so I'm just sending this problem to
the mailing list. I'm not sure whether it is an ANTLR issue or an
antlr3-maven-plugin issue.)
I have the setup below. If I run it I get the following result:
hi...@centaur ~/workspaces/default/JavaParser $ mvn clean compile ; tree

Note the strange location of XLexer.java. If I comment out "import L;"
and uncomment "LETTER : 'X' ;" everything works as expected and
XLexer.java ends up next to XParser.java.
How do I get "import" to work properly?
Cheers,
Hilco
