Programmtically load genmymodel XMI export file with Epsilon [message #1858315]

I am trying to load an XMI export from genmymodel using Epsilon and specifically with a model constructed from org.eclipse.epsilon.emc.uml.UmlModel(), then calling model.load using the below props:

properties.put(EmfModel.PROPERTY_MODEL_URI, s"${modelURI.toString}")
properties.put(
EmfModel.PROPERTY_METAMODEL_URI,
"http://www.eclipse.org/uml2/5.0.0/UML,http://www.eclipse.org/emf/2002/Ecore"
)

I can successfully construct one but I believe it is not loading without error. I am also trying to get access to and ECore extension I added in genmymodel which I see inside the XMI file as an xmi:Extension extender="http://www.eclipse.org/emf/2002/Ecore" but when I try to access the attr.getEAnnotations() method, I get back nothing though I see it in the xmi file for the attribute.

I would like to get full access to the annotations from genmymodel as this is how I wish to get additional information into the model. Any suggestions are greatly appreciated.

Could you please share a minimal example we can use to reproduce the issue you're encountering?

Thanks,

// NOTE: This is Scala code, may need to tweak for Java.

model = new org.eclipse.epsilon.emc.uml.UmlModel()
properties = new StringProperties
properties.put(EmfModel.PROPERTY_MODEL_URI, s"${modelURI.toString}")
properties.put(EmfModel.PROPERTY_METAMODEL_URI, "http://www.eclipse.org/uml2/5.0.0/UML,http://www.eclipse.org/emf/2002/Ecore")
model.load(properties, new DefaultRelativePathResolver())

I can access the model and all Classes using below:
val allClasses = model
.getAllOfType("Class")
.asScala
.map(_.asInstanceOf[org.eclipse.uml2.uml.Class])

It is reading the model, but none of the annotations seem to be accessible.

If you could share a complete and self-contained minimal example (including a sample model) in Java that would help a lot.

Thanks,

I am trying to do it in the sandbox with a minimal exported genmymodel model. I am not sure what I need to place into the metamodel window. I assume I paste the XMI text into the model window? If so, what goes into the metamodel window?

I attached the XMI file as it is the smallest I could create with an EAnnotation.

I'm not sure that EMF supports xmi:Extension: https://www.eclipse.org/forums/index.php?t=tree&th=124679&goto=381546&#page_top

In the attached example, querying the contents of the root Model element, only returns the package import and the class under it.

Thank you for your assistance. I switched to Paypyrus from genmymodel and seems much better now. I am very grateful for all the work done on this tooling.
