I have a

Strings.xtext

file, which is a very simple grammar

Here is my workflow:

module de.bmw.rhmi.resource.GenerateStrings

import org.eclipse.xtext.xtext.generator.*
import org.eclipse.xtext.xtext.generator.model.project.*

var rootPath = ".."
var projectName = "de.bmw.rhmi.resource"

Workflow {
	
	component = org.eclipse.emf.mwe2.ecore.EcoreGenerator {
		genModel = "platform:/de.bmw.rhmi.resource/src/main/resources/Image.genmodel"
		srcPath ="platform:/resource/${projectName}/src"
	}
	
	component = XtextGenerator {
		configuration = {
			project = StandardProjectConfig {
				baseName = "de.bmw.rhmi.resource"
				rootPath = rootPath
				runtimeTest = {
					enabled = true
				}
				genericIde = {
					enabled = true
				}
				mavenLayout = true
			}
			code = {
				encoding = "UTF-8"
				lineDelimiter = "\n"
				fileHeader = "/*\n * generated by Xtext \${version}\n */"
			}
		}
		language = StandardLanguage {
			name = "de.bmw.rhmi.resource.Strings"
			fileExtensions = "strings"

			serializer = {
				generateStub = false
			}
			validator = {
				// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
			}
		}
	}
		
	component = org.eclipse.emf.mwe2.ecore.EcoreGenerator {
		genModel = "platform:/de.bmw.rhmi.resource/src/main/resources/Profile.genmodel"
		srcPath ="platform:/resource/${projectName}/src"
	}
		
}

as you can see, in my workflow, along with using the XText Generator, I want to generate resources from Profile.genmodel and Image.genmodel (they both have also Image.ecore and Profile.ecore) files.

However when I run the workflow I get the following error:

Caused by: java.lang.RuntimeException: Cannot create a resource for 'platform:/de.bmw.rhmi.resource/src/main/resources/Image.genmodel'; a registered resource factory is needed
        at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.getResource(ResourceSetImpl.java:403)
        at org.eclipse.emf.mwe2.ecore.EcoreGenerator.preInvoke(EcoreGenerator.java:95)

        at org.eclipse.emf.mwe2.launch.runtime.Mwe2Runner.run(Mwe2Runner.java:102

Where should this factory be and how can I use it? I can provide a sample project if necessary.

Thanks
