This is what I use:
// multiple-line comments
ML_COMMENT : NESTED_COMMENTARY { $channel=HIDDEN; } ;
fragment NESTED_COMMENTARY :
'/*'
( options {greedy=false;} : . )*
( NESTED_COMMENTARY ( options {greedy=false;} : . )* )*
'*/'
;
(note that this works using ANTLR 3.1.3 from Mar 2009, kinda old but I
think should still work with current ANTLR versions)
Perhaps you can adapt it to your language....
Hope this helps
