Hi,

I get the below exception while running the maven build for a test,

ERROR WorkflowRunner     - org.xml.sax.SAXParseException: Content is not allowed in prolog.
org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.xml.sax.SAXParseException: Content is not allowed in prolog.
        at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.handleDemandLoadException(ResourceSetImpl.java:315)
        at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.demandLoadHelper(ResourceSetImpl.java:274)
        at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.getResource(ResourceSetImpl.java:397)

while the test runs fine when run as a Junit PluginTest.I pass new ResourceSetImpl() to a method which expects ResourceSet which then internally calls the methods mentioned in the stack trace. I also tried the code,

Injector injector = new MyModelStandaloneSetup().createInjectorAndDoEMFRegistration();
XtextResourceSet resourceSet = injector.getInstance(XtextResourceSet.class);

instead of creating a new object ResourceSetImpl but it does not build properly and the output is not generated.

Any hints on what the issue is?

Thanks in Advance,
Latha

Hi Latha,

I have the same problem.

If I run my tests as junit tests, everything is fine. If I run them using maven tycho, I get the same SaxParseException "Content is not allowed in prolog."

Could you solve your problem?
Or anyone else?

Thx in adance,
Ingo

Hi Ingo,

can you please share a little complete example project.
btw do you know of the xtext way of unit tests (YourDslInjectorProvider + XtextRunner)

Hi Christian,

stupid me. I didn't recognize the section on unit tests in the XText documentation: http://eclipse.org/Xtext/documentation.html "Unit Testing the Language".

My unitests were missing the annotations above the test class. Adding them solved my problem:

@InjectWith(DomainmodelInjectorProvider)
@RunWith(XtextRunner)
class TestSomeStuff {
}

Thanks anyway for the fast reply.
I should have looked better, though -.-
