this is cause the option is tied based on naming convention with the grammar file
=> rightclick on workflow run as -> mwe 2 workflow

java.lang.IllegalStateException: Unresolved proxy "http://www.prolifics.com/jpl/JPLAsc"#STag. Make sure the EPackage has been registered

Then I added

<plugin>
<extension point="org.eclipse.emf.ecore.generated_package">
<package
uri = "http://www.prolifics.com/jpl/JPLEditor"
class = "com.prolifics.jpl.jPLEditor.JPLEditorPackage"
genModel = "model/generated/JPLEditor.genmodel" />
</extension>
<extension point="org.eclipse.emf.ecore.generated_package">
<package
uri = "http://www.prolifics.com/jpl/JPLAsc"
class = "com.prolifics.jpl.jPLEditor.JPLEditorPackage"
genModel = "model/generated/JPLAsc.genmodel" />
</extension>
</plugin>

It is resolved but new error came as : java.lang.ClassCastException: com.prolifics.jpl.jPLEditor.impl.JPLEditorFactoryImpl cannot be cast to com.prolifics.jpl.jPLAsc.JPLAscFactory

<package

class = "com.prolifics.jpl.jPLEditor.JPLEditorPackage"
is false for sure
