Running Ecore2Java task without headless Eclipse [message #532008]

I'm trying to run the Ecore2Java task without using a headless Eclipse instance. Is this possible at all?

I tried defining a taskdef for the Ecore2Java task as follows

<taskdef name="emf.Ecore2Java" classname="org.eclipse.emf.importer.ecore.taskdefs.EcoreGeneratorTask ">
<classpath>
<fileset dir="C:\eclipse\plugins" includes="*.jar" />
<fileset dir="C:\eclipse\ecore2java" includes="*.jar" />
</classpath>
</taskdef>

I had to extract out emf.ant.tasks.jar and importer.ecore.tasks.jar from the eclipse plugins jars and make it available on the classpath but my build fails with this message

java.lang.RuntimeException:
org.eclipse.emf.common.util.DiagnosticException: RuntimeException: Cannot creat
e a resource for 'file:/<path>/src/main/metamodel
/Workflow.genmodel'; a registered resource factory is needed

So I'm obviously missing something. I'm still playing with it but wanted to find out if it would be possible in the first place. Any pointers would be greatly appreciated.

I doubt it.

When you run without Eclipse all the global registrations normally done
via the plugin.xmls will need to be done manually.

I'm not sure it's possible in the end. Why is it necessary?

Necessity - I'm trying to invoke Ecore2Java through my custom build system. If I call a headless Eclipse instance from my build I'm running into classloading issues between my build system and the Eclipse AntRunner. So I was trying to see if I can bypass a headless Eclipse instance.
