[antlr-interest] Lexer.java output in wrong directory

[Hilco Wijbenga]

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:

            `-- x
                |-- XParser.java
                `-- X_L.java

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

X.g:

@header {

}
//LETTER : 'X' ;
x : 'x' LETTER ;

L.g:
lexer grammar L;
LETTER : 'X' ;
