Hi,

I'm trying to go through the tutorial at https://eclipse.org/Xtext/documentation/305_xbase.html .

Mapping a datatype to a Java element, does not seem to work.

Instead at the line:

datatype Date mapped-to java.util.Date

I get the following error message:

Couldn't resolve reference to JvmType 'java.util.Date'.

I've tried adding a reference to the common Java types in the language definition, like this:

language = StandardLanguage {
	name = "org.example.domainmodel.Domainmodel"
	fileExtensions = "dmodel"
	referencedResource=
		"platform:/resource/org.eclipse.xtext.common.types/model/JavaVMTypes.genmodel"

	serializer = {
		generateStub = false
	}
	validator = {
		// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
	}
}

However i still get the same error.

Am i or the tutorial missing something?

Does your grammar inherit from xbase?

e.g grammar org.xtext.example.mydsl1.MyDsl with org.eclipse.xtext.xbase.Xtype

Thank you Christian, this works!

The grammar in the tutorial inherits from org.eclipse.xtext.common.Terminals.

Maybe the tutorial should be updated accordingly:
