Hi all,

we use QVTo for our stack of model transformations in our products. We historically had to modify some plugins to mainly avoid undesirable dependencies in our products and other issues. I'd like to share this improvements here, looking for a chance to contribute them and finally getting rid of them. Im using the Kepler release, btw.

- org.eclipse.m2m.qvt.oml.emf.util.ui. States depends on Java 1.5, but uses Java 1.6 API. This shows compilations errors when using Java 1.5 compliance in the workspace. Probably the original developer had its workspace improperly setup. Affected classes:
* Line 55, ResourceDesintationChooser.
* Line 64, ResourceSourceChooser.
* Line 38, ResourceSourceDestChooser.
Solution -> replace by String.length() == 0

- org.eclipse.m2m.qvt.oml.emf.util.ui. Dependency on org.eclipse.emf.codegen.ecore.ui. It does not actually depend in any specific API of that bundle, but rather depends in reexports. I'd suggest to change to the actual dependencies, however, that would imply breaking clients (unfortunately, it's reexported). If you're still interested, it should be substituted by:
* org.eclipse.emf.ecore.edit;bundle-version="[2.5.0,3.0.0)",
* org.eclipse.emf.edit.ui;bundle-version="[2.5.0,3.0.0)",
* org.eclipse.ui.ide;bundle-version="[3.5.0,4.0.0)"

- org.eclipse.m2m.qvt.oml.editor.ui. We do not include JDT in our products, but this plugins depends on the JDT API, and makes it mandatory to have the whole JDT feature in our RCP, basically just for icons and a view ID. I understand its not desirable duplicate icons, neither hardcode view IDs, but I'd like to put this out, maybe there are better options. For instance, refactoring those dependencies in a new bundle (org.eclipse.m2m.qvt.oml.editor.jdt.ui).

So thats all. If any of the above sounds reasonable, I could provide some patches.

Best Regards!

Hi Victor

QVTo is active again. Please supply patches. A Bugzilla is mandatory for
IP purposes.

https://github.com/eclipse/qvto seems to be working at the moment. No
Gerrit (yet).

Alright, I'll create some bugzillas and submit patches.

This was fixed by commit 355aa060932b4bfdca1dbdfe896be02dc177d274 on

This is trivial; no need for a patch; just a Bugzilla for tracking.

QVTo already has image registries. It is probably easy to reuse
something already within QVTo to replace JavaUI.getSharedImages(); e.g.
CompletionProposalUtil.getImage(). If you got a few spare moments you
can see how many other equivalent registries have appeared through
diverse development.

The four *.gif files can then be copied to the local icons folder. No
need for an extra plugin.

Hi Victor,

Thank you very much for sharing your knowledge. It's nice to improve QVTo bits in a way which helps to utilize it under different circumstances.

I've committed changes for both bugs. Will be available in next milestone (Eclipse Luna M5, January 31, 2014).

As for JDT dependencies in "org.eclipse.m2m.qvt.oml.emf.util.ui" plug-in there were two icons and one string. Not so much.

As for Java 1.5 compatibility - we're planning to switch BREE to Java 6 (https://bugs.eclipse.org/bugs/show_bug.cgi?id=424052). I think this will happen till Luna M6 milestone (see http://wiki.eclipse.org/Luna/Simultaneous_Release_Plan).


Regards,
Sergey Boyko.

Sergey,

your quick support is much welcome. Regarding the Java 1.5 compatibility, we are using 1.6 so it's not a blocker for us. However, I realised the bundle stated 1.5 and therefore I reported the inconsistency. I was not aware Equinox is switching to 1.6, good to know.

I assume the next QVTo release would be 4.4, right?

Best Regards,

Victor,

No, we will stay on 3.x stream so the next release is 3.4.0 (it won't introduce any API breaking changes).

Project's link: http://projects.eclipse.org/projects/modeling.mmt.qvt-oml/releases/3.4.0

Sergey,

I actually mistyped the version, wanted to refer to 3.4.0, sorry. Thanks for the info!

Hi again, Sergey,

any chances the above fixes could be included in Kepler SR2?

Cheers,

Hi

The Kepler build job does not loook in good shape. 4 fails since Kepler
release

a) because the Hudson Job rename has not been accommodated in the scripts
b) the RMAP references are inappropriate for a maintenance build

and probably a general review is needed to ensure that it works as a
maintenance build without crunching the luna builds.

(most of the above can be found by looking at evolution of the QVTd
build that like QVTo is a single job offshoot of the OCL build.)

But since QVTo has not yet moved to a HIPP and upgrade must suffer the
eccentricities of the communal Hudson.

Far from insuperable, but very little on Hudson is trivial.

Regards

Ed Willink

Hi Ed,

that's quite unfortunate. I'll interpret your answer as "unfortunately, there's much to do before that could happen, and we are lacking on resources"

Can only hope you guys find some time for the maintenance builds.
