[antlr-interest] error(208)
P.N.

Hello!
Using the following rules for grammar (ESC_SEQ defined as fragment):
root : object;
object : '{' props '}';
props : prop (',' prop)*;
prop : ID ('=' PV | '+' | '-');
PV : STRING | object | INT;
ID : ('a'..'z'|'A'..'Z') ('a'..'z'|'A'..'Z'|'0'..'9'|'_')*;
INT : '0' | ('1'..'9') ('0'..'9')*;
WS : (' '|'\t'|'\r'|'\n') {$channel=HIDDEN;};
STRING : '"' (ESC_SEQ | ~('\\'|'"'))* '"';
When I try to generate the Java code, the following error message is shown:
"error(208): The following token definitions can never be matched
because prior tokens match the same input: INT,STRING"
Why do I get this message, as every lexical rule has its own starting
character?
Kind regards
Peter
