Execute migration with Edapt [message #897817]

Hello!

I installed the project Edapt http://www.eclipse.org/edapt/, creates the history of my ecore model and prepared a new "release Edapt". In the tutorial http://www.eclipse.org/edapt/libraryexample.php I'm at the point "Migrator".
I.e. the execution of operations to convert my data files from old to new Ecore model.

Quote:

The migration execution can be integrated directly into the editor code, as Listing 3 shows. The method checkMigration must be called at the beginning of the method createModel in the library editor.

But i don't have the méthod "createModel", because i don't have the project "xxx.editor". i have the xxx.model (with .ecore), xxx.edit and xxx.diagram (generated with .gmfgen).

I don't find how launch the migration with Edapt...

Any suggestions?

Hi,

the example is about integrating the migration into the editor that can
be generated from the genmodel with EMF. To generate the editor open the
genmodel and select "Generate Editor" from the context menu.
I do not know about your application scenario, but probably you do not
want to use the editor since you did not generate it. The example code
in Listing 3 however demonstrates what you need to do to integrate it
into any kind of editor/application that loads EMF models from
XMI-Resources. If you pass in the URI of the XMIFile it will be migrated
if a migration plugins has been generated with Edapt and is enabled in
the launch config.

Cheers,
Maximilian

Hi,

just like the starter of this topic, I am experiencing problems trying to execute the migrator. I am following the Edapt tutorial as found on the website.

What I've done so far:

Created an example ecore model
Created a 1.0 release (also reflected in the nsUri) with Edapt
Generated all the model, edit and editor plugins from the ecore model
Started up a new Eclipse instance and tested the creation of a model instance using the generated editor
Made a small modification to the meta-model, and created a 1.1 release with Edapt, including changing the nsUri.
Verified to see whether the model instance created earlier could not be opened in the run-time instance due to the NsUri being changed.
Then, tried to modify the editor code in the createModel method to execute the model migrator. Opening the model with the modified editor now results in the error message "No migrator found".

Debugging the code it became clear the the MigratorRegistry does not contain a suitable migrator for the 1.0 version of the meta-model. I've looked at implementing the 'org.eclipse.emf.edapt.migrators' extension point, but fail to achieve in this.

Can someone please look at the enclosed attachment and see what I am doing wrong here? Furthermore, is there any documentation besides the tutorial available? The documentation link on the website points to a non-existing website.

Thank you in advance!

Never mind. Got it to work! Apparently the path defined in the extension point was wrong.... Mad

Kind regards,

Hi Niels Brouwers,

I'm new to EMF and EDpat, and currently experiencing the same sort of problem you had when you first tried to use EDapt. I also performed all the steps you mentioned in your bullet points list, but I get stuck when it comes to executing the migrator, could you please send me an example project of how you used EDapt successfully?

Your help would be highly appreciated.

Awaiting your reply please,

Thanks,

Bestoon Jaff

Hi Maximilian,

I think lots of people have had troubles and difficulties following the library example of the EDapt tutorial, especially the Migrator section of that tutorial.

Could you please kindly update the library tutorial and add more details of how one can register a history in the migrator extension point?

I.e. could you kindly review the Migrator section and add the missing detail which has mad troubles for people trying to use EDapt tool?

Thanks a lot in advance,

Kind Regards,

Bestoon Jaff

Hi,

we added an image of a registered history, which should help.
However this is more related to Eclipse RCP development overall. So you should maybe checkout this:
https://wiki.eclipse.org/FAQ_What_are_extensions_and_extension_points%3F

Cheers

Hi Johannes,

Thank you very much for your kind reply. Given that some of us (me included) are new to EMF and Edapt that is why we couldn't follow the tutorial successfully. I know that for people already familar with EMF, it could be straightforward to follow such a tutorial.

Thanks once more.

Btw, my NPE issue has not yet resolved :-( I replied to your message from the other post and attached my trial version of the library. Here I re-attached the project and I do very much appreciate if you could take a look and see what is wrong with it. I compared it to the sample library project which ships with EDapt 1.2.2, but could not find the source of the problem. Your help is highly appreciated.

Thanks,

Jaff
