Cannot remove org.eclipse.xtext.common.Terminals from gramma [message #1066809]

Hey,

I would like to remove the org.eclipse.xtext.common.Terminals import from my grammar to avoid the following error message:

The following token definitions can never be matched because prior tokens match the same input: RULE_INT

It is caused by my terminal rule:

terminal VALUE:
	('a'..'z' | 'A'..'Z' | '_' | '\\' | '\\(' | '\\)' | '\\ ' | '\\@' | '0'..'9')+;

If I remove the grammar "with org.eclipse.xtext.common.Terminals" from the header of the file, the terminal rule is marked with an error: Cannot create datatype VALUE.

Is there a way to completely remove org.eclipse.xtext.common.Terminals?

Thank you.

Kon

Hey Christian,

I have tried this:

grammar com.project.test.properties.MyDsl /*with org.eclipse.xtext.common.Terminals*/

But it results in:

index.php/fa/15477/0/

with the error message: Cannot create datatype VALUE

Is this a bug? I'm using 2.4.2.

Thank you.

Hi,

Thank you Christian Smile

grammar com.project.test.properties.MyDsl /*with org.eclipse.xtext.common.Terminals*/

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

This works now Smile

Thank you!
