Modify error message from IResourceValidator [message #1754033]

I am using cross-reference from xcore. If an entry does not have a valid reference, xcore will throw an error like this:

Couldn't resolve reference to Test 'trial'.

I don't want xcore to specify the grammar name 'Test' in the error message as the user does not really care about the grammar part. "Couldn't resolve reference to 'trial'" is enough for me.

How can I modify the error message that the validator is throwing?

The extension point is ILinkingDiagnosticMessageProvider

I created my own custom diagnostic message provider.

class CustomDiagnostic extends LinkingDiagnosticMessageProvider {
	override DiagnosticMessage getUnresolvedProxyMessage(ILinkingDiagnosticContext context) {
		val DiagnosticMessage diagnostic = super.getUnresolvedProxyMessage(context)
                String msg = "my custom msg"
		return new DiagnosticMessage(msg, diagnostic.getSeverity(),
			diagnostic.getIssueCode(), diagnostic.getIssueData())
	}
}

But when I bind it with my runtime module, I get the error saying "The method bindILinkingDiagnosticMessageProvider() must override a superclass method."

I added this in my runtime module:

	override Class<? extends ILinkingDiagnosticMessageProvider> bindILinkingDiagnosticMessageProvider() {
		return CustomDiagnostic 
	}

why not simply

def Class<? extends ILinkingDiagnosticMessageProvider> bindILinkingDiagnosticMessageProvider() {
return CustomDiagnostic
}
