Hi,

I hava a project with many Ecore-models. In order to (re)generate the code for all Ecore models with one click I defined a workflow like this:

Workflow {
	
	bean = org.eclipse.emf.mwe.utils.StandaloneSetup {
		scanClassPath = true
		platformUri = "../.."
		registerGenModelFile = "platform:/resource/foo/bar.genmodel"
	}
	
	// Models
	component = org.eclipse.emf.mwe2.ecore.EcoreGenerator {
		genModel = "platform:/resource/foo2/bar2.genmodel"
		srcPath = "platform:/resource/foo2/src"
		generateEdit = true
	}
	
        // more models...
	component = org.eclipse.emf.mwe2.ecore.EcoreGenerator {
	...

The code generation works fine. However I noticed that the generator does not take @generated NOT annotations into account. I have heard of the generation gap pattern but I would like to avoid it.
So my question is, if it is somehow possible to tell the EcoreGenerator (with annotations in the generated code) that previously generated code was modified and should not be overwritten.

Thanks,
Johannes

Hi,

i think you would have to come up with your own version of EcoreGenerator
Workflow Component that does NOT disable JMerge

Hi

You might find

org.eclipse.ocl.examples.build.utilities.GenerateModel
org.eclipse.ocl.examples.build.utilities.GenmodelReloader

helpful. They were developed before
org.eclipse.emf.mwe2.ecore.EcoreGenerator was available.

I suggest adjusting EcoreGenerator to add some more options and then
contribute it back.

Regards

Ed Willink
