Thanks.
But I found it also failed in eclipse plugin.
I tried the following grammar.
---------------
otherFilterSpec
: OTHERFILTER '(' CONST_STRING ')'
;
fragment DIGIT : '0'..'9';
fragment LOWER : 'a'..'z';
fragment UPPER : 'A'..'Z';
CONST_STRING : '"' (LOWER|UPPER|DIGIT)* '"';
---------------
parsed ok.
but the following:
---------------
otherFilterSpec
: OTHERFILTER '(' CONST_STRING ')'
;
constString: ' " ' (LOWER|UPPER|DIGIT)* ' " ';
fragment DIGIT : '0'..'9';
fragment LOWER : 'a'..'z';
fragment UPPER : 'A'..'Z';
CONST_STRING : '"' (LOWER|UPPER|DIGIT)* '"';
---------------
failed.
I don't know why changing from rule to TOKEN works.
