Hello,

I was trying to write the basic grammar in xtext. But it is showing me the error

required (...)+ loop did not match anything at input 'grammar'

Please, how to clear this error.

Thank you

---- Below is the xtext code---

grammar org.eclipse.xtext.common.Terminals hidden(WS, ML_COMMENT, SL_COMMENT)

import "http://www.eclipse.org/emf/2002/Ecore" as ecore

terminal ID: '^'?('a'..'z'|'A'..'Z'|'_') ('a'..'z'|'A'..'Z'|'_'|'0'..'9')*;
terminal INT returns ecore::EInt: ('0'..'9')+;
terminal STRING:
'"' ( '\\' . /* 'b'|'t'|'n'|'f'|'r'|'u'|'"'|"'"|'\\' */ | !('\\'|'"') )* '"' |
"'" ( '\\' . /* 'b'|'t'|'n'|'f'|'r'|'u'|'"'|"'"|'\\' */ | !('\\'|"'") )* "'"
;
terminal ML_COMMENT : '/*' -> '*/';
terminal SL_COMMENT : '//' !('\n'|'\r')* ('\r'? '\n')?;

terminal WS : (' '|'\t'|'\r'|'\n')+;

terminal ANY_OTHER: .;
