Cannot run extended 15 minute tutorial [message #731526]

Hello,

I have recently started studying the documentation for Xtext and I am unable to properly generate a unit test for the example language provided in the section "15 minutes tutorial - Extended".

When writing the example code I get the error "Couldn't resolve reference to JvmAnnotationType 'InjectWith'." and I am unable to figure out which is the source of the problem.

I have imported org.eclipse.xtext.junit4 in my source file but that doesn't seem to help at all and I can see the org.eclipse.xtext.junit4_2.0.1.v201108020636.jar file is referenced in Plug-in Dependencies.

Could anyone help me with this? I'm sure that it's just some configuration step that I'm missing but I can't find any lead on Google and the documentation is pretty vague on this matter.

Hi,

did you add the corresponding imports?

package test

import org.eclipse.xtext.junit4.InjectWith
import org.junit.runner.RunWith
import org.eclipse.xtext.junit4.XtextRunner
import org.eclipse.xtext.example.domainmodel.DomainmodelInjectorProvider

@InjectWith(typeof(DomainmodelInjectorProvider))
@RunWith(typeof(XtextRunner))
class Test {
	
}

Now I only have one error left. Eclipse does not seem to recognize assertSame even when I import the package for it. My code is:

import org.eclipse.xtext.junit4.InjectWith
import org.junit.runner.RunWith
import org.eclipse.xtext.junit4.XtextRunner
import org.example.domainmodel.DomainmodelInjectorProvider
import org.example.domainmodel.domainmodel.Domainmodel
import org.example.domainmodel.domainmodel.Entity
import org.eclipse.xtext.xtend2.lib
import com.google.inject.Inject
import org.eclipse.xtext.junit4.util.ParseHelper
import org.junit.Test
import org.junit.Assert

@InjectWith(typeof(DomainmodelInjectorProvider))
@RunWith(typeof(XtextRunner))
class ParserTest{
	
	@Inject ParseHelper<Domainmodel> parser
	
	@Test
	def void testParseDomainmodel(){
		val model=parser.parse("
			entity MyEntity{
				parent: MyEntity
			}
		")
		
		val entity = model.elements.get(0) as Entity
	    assertSame(entity, entity.features.get(0).type)
	}
}

When I modify the ParserTest class to inherit from TestCase then I get the following error for assertSame: "Incompatible receiver type. Expected java.lang.String but was ParserTest"

Could you please help me with this issue?

Hi,

same as in Java: import static org.junit.Assert.*

I have a problem with the code generator example in the extended 15 minute tutorial. When I opened the Eclipse application with my plugin the generated code in xtend-gen contained the <<IF>> tokens and I removed the generated code from the project but I cannot regenerate it no matter what I try. Does anyone know which operations trigger the code generator for xtend-gen?

Hi,

Are you talking about the Xtend-gen Folder in the Host project or about the src-gen in the Model project in the runtime Application. In both cases a clean Build on the project should trigger a rebuild. what exactly did you do when Removing the generated Code?
