[antlr-interest] maven & gunit - Gunit tests don't run

[Selena Phillips]

I cannot get GUint tests to run in my maven setup. When I run mvn compile,
everything compiles fine. The lexer and parser classes are generated as
expected in target/generated-sources. However, when running mvn tests, all
the junit tests run and I get this output:

-----------------------------------------------------------
 G U N I T   R E S U L T S
-----------------------------------------------------------

Summary :
Tests run: 0,  Failures: 0,  Invalid: 0

The gunit report folder is created, but is empty. There are no error
messages or exceptions reported.

Directory structure:

There are just a few simple tests in the gUnit file for a simple grammar:

gunit Testy;

qualifiedName:
"helloWorld" OK

IDENTIFIER:
"abc123" OK
"abc*%123" OK
"123abc" FAIL

Here is an excerpt from my grammar:

grammar GrammarName;

options {
    language = Java;
}

@lexer::header {
  package org.companyname.projectname.parser;
}

@parser::header {
  package org.companyname.projectname.parser;
}

qualifiedName
    :   IDENTIFIER ('.' IDENTIFIER)*
    ;

IDENTIFIER
    :   IDENTIFIER_CHARS*
    ;

fragment
IDENTIFIER_CHARS
    :    (IDENTIFIER_START) (IDENTIFIER_PART)*
    ;

fragment
IDENTIFIER_START
    :   '\u0024'
    |   '\u0041'..'\u005a'
    |   '\u005f'
...... (Way too long to repeat here.)

fragment
IDENTIFIER_PART
    :   '\u0000'..'\u0008'
    |   '\u000e'..'\u001b'
    |   '\u0024'
    |   '\u0030'..'\u0039'
........(Ditto)
