[CDO] Can't get repositories to checkout properly [message #1840078]

I'm new to CDO - we are currently using Papyrus with Papyrus Compare and EGit - but keen to see if CDO is better for collaboration. Have downloaded the latest server with Oomph and can run that ok. In any client based on 2020-12 and up, if I add the server and then try a "Checkout As" the Finish button at the end of the wizard doesn't do anything (looking at the workspace log, it throws an exception setting a Property as part of the Finish action).

If I do a simple "Checkout", I can se the repository in the Project view and can add folders and models but it won't let me add a Papyrus model to it (it doesn't recognised the repo as a valid parent).

I have tried creating local repositories rather than connecting to the local "remote" one and I get exactly the same result. If there's something I'm doing wrong I'd be grateful for any pointers!

Thanks

That exception (with its stacktrace) might help me understand your problem.

The only not obvious step that you might have missed is the deployment of the CDO-native versions of all the meta models used in Papyrus. They can be found in https://git.eclipse.org/c/papyrus/org.eclipse.papyrus-collaborativemodeling.git/tree/cdo , but I currently do not know if/where the Papyrus team provides them in the form of p2 repositories. At least you can (should) check whether you're currently using the "normal" (in CDO terms "legacy") versions of these models. Just specify the system property -Dorg.eclipse.emf.cdo.view.REPORT_LEGACY_MODELS=true and watch the consol while you're working with Papyrus.

The only p2 repository seems to be on the CI instance: https://hudson.eclipse.org/papyrus/job/Papyrus-CDO/lastSuccessfulBuild/artifact/repository/

Apologies - should have included the stack trace, which is below:

I will also look at the metamodel deployment (which I was indeed unaware of).

Many thanks

I could reproduce your problem and I can confirm that it's not at all related to Papyrus. If you submit a bugzilla I'll analyze and fix the problem with high priority.
