Hi
Today, I think the EMF GenModel changes should just be an opportunity.
The new EAnnotation support should allow UML's
<genAnnotations
source="http://www.eclipse.org/emf/2002/GenModel/importer/org.eclipse.uml2.uml.ecore.importer";>
<details key="DUPLICATE_FEATURES" value="PROCESS"/>
<details key="DUPLICATE_FEATURE_INHERITANCE" value="PROCESS"/>
...
to be visible and editable in the EMF editors.
However again today, with 2 bug fixes on the new support not yet
available in an N-build, it is not possible to rebuild the OCLUML.uml
models; the genmodel takes a long time as usual but many of the
generated files terminate after the imports, which is often an
indication of bad templates.
I suspect that the EMF template evolution to support @deprecated/@since
tags is breaking for UML2. There is new GenModelUtil API used by the
templates and since this is build time API there is no need to provide
runtime-level conditionalization. Anything that uses EMF 2.14 code
generation must support EMF 2.14. For OCL and QVTd, I just had to add an
extra import of GenModelUtil and merge my variant Class.javajet with the
evolved EMF Class.javajet. For QVTd where code generation can be a
user-compile time activity, I considered adding conditionalisation on
all the new API so that QVTd would be Oxygen installable, I'm still
considering but since QVTd graduates this year I might decide that it
graduates on current code unless UML has died....

I think you are misinterpreting "require UML2's extended GenModel to
take action" as synonymous with "the changes are bad."
Any change (good or bad) to the GenModel.ecore affects (at least
potentially) UML's extended GenModel implementation.
http://git.eclipse.org/c/emf/org.eclipse.emf.git/log/plugins/org.eclipse.emf.codegen.ecore/model/GenModel.ecore
Also any change to templates (good or bad) affects (at least
potentially) UML's specialized templates:
http://git.eclipse.org/c/emf/org.eclipse.emf.git/log/plugins/org.eclipse.emf.codegen.ecore/templates/model/Class.javajet
We can all be thankful (and I certainly am!) that Itemis consistently
sponsors my contributions and that Dennis Hübner of TypeFox does the
Releng work on my behalf.
Note that lack of signing support for Buckminster builds will become a
significant problem for someone, or perhaps everyone, when the
foundation disables that service.

Hi Ed,
Can you tell me what are the changes that have been made and will be
bad for photon w.r.t. EMF generator part?
Thanks.
Best.

Objet : Re: [modeling-pmc] UML2 and Photon
Kenn,
That's pretty bad for Papyrus, parts of OCL, and parts of EMF
Compare. :-( And I'm not sure which other release-train parts are
downstream of those parts...
Downstream consumers should note that parts of UML2 (i.e., the
generator parts) don't work with the latest EMF (i.e., the generator
parts of it) because any changes I make to the GenModel (and I made
many changes recently) require UML2's extended GenModel to take
action. So we can't just feed the Oxygen version of UML2 into the
Photon train (at least not all of UML2's parts).
Regards,
Ed

PMC,
I just wanted to give you a heads up that there are currently no
plans for UML2 to participate in the upcoming Photon simultaneous
release, due to lack of funding. Unfortunately, this means that
dependencies will break when the aggregation file is disabled by the
EMO immediately following M4.
If anyone is interested (or knows someone who might be interested)
in helping ensure that UML2 is kept up to date and that it can
participate in the Photon release, please reach out to me directly.
Thanks,
Kenn
