I have few methods which are in built with my product. So I no need to implement them externally. Editor should check them from jar.

Well this question has no easy solution

(a) asuming your libary can be expressed in your dsl itself. and the dsl file containing project is a java project the you can put a jar containing the libary dsl files to the classpath of that project and it will work out of the box

(b) you should have a look at the concept of scoping. you could e.g. provide EObjectDescriptions for our libary inside a customization of DefaultGlobalScopeProvider

(c) you could customize org.eclipse.xtext.linking.ILinkingDiagnosticMessageProvider.getUnresolvedProxyMessage(ILinkingDiagnosticContext) and return null in certain situations

Hi,

Could you please tell me which method creates red underline if it doesn't find cross reference in HyperlinkHelper class?

Or, Can I at least remove red error underline?

hyperlinkhelper uses resolved cross refs. it has ZERO todo with red underlining.

xtext cross referenced a resolved by the linking infrastructure using the scope provided by scopeproviders.
these use the class i gave you to produce errors.

the hyperlink helper uses at cross reference places that resolved references to do the hyperlinking
(it uses eobjectatoffsethelper)

i still dont know what you actually want to slove?

hyperlinking?
scoping?
ged rid of the error messages?

I want to get rid of error messages in case there is no cross reference available. Because I have some in built methods which are not visible to the code. So in such conditions I don't want to show error line. It is fine if they obey parser rule

Hi,

I have extended HyperlinkHelper
@Inject
private EObjectAtOffsetHelper eObjectAtOffsetHelper;

but how can I override

public EObject resolveCrossReferencedElementAt(XtextResource resource, int offset) {
INode node = getCrossReferenceNode(resource, new TextRegion(offset, 0));
if (node != null)
return getCrossReferencedElement(node);
return null;
}

which is in EObjectAtOffsetHelper class.

Yes but that has zero todo with the error message.
What is how to heal with unresolved references when hyper linking
