| Re: [cross-project-issues-dev] CVS support plugin discontinuation - SimRel build changes needed |
Hi Eike,
Actually CDO does depend on Mylyn, and therefore (until 2021-12) on CVS:
EMF CDO depends on EMF Compare's contribution:org.eclipse.emf.cdo.compare -> org.eclipse.emf.compare
EMF Compare depends on EGit's contribution:org.eclipse.emf.compare.egit -> org.eclipse.jgit
EGit depends on Mylyn's contribution:org.eclipse.mylyn.github.feature.feature.group -> org.eclipse.mylyn_feature.feature.group
(Note that despite the name org.eclipse.mylyn.github.feature.feature.group is contributed by EGit to simrel)
The difference is the granularity of the dependencies. For SimRel dependencies are normally handled at the contribution level. At the feature/bundle level there may indeed be no dependencies from CDO -> Mylyn/CVS, but with many contributions being interdependent on each other, and Mylyn historically cutting across so many projects, something that disabled Mylyn causes many things to be easily disabled.
Of course this problem is hindered by Mylyn being under-resourced at the moment.
I hope that helps,Jonah

Eike / Ed W. / Lorenzo / Team,
Let me clarify. While contributing Eclipse Project M1 to SimRel 2022-03 M1, SimRel Aggregator Validation found many dependency issues "directly" or "indirectly" related to the removal of CVS in Eclipse Project. Mylyn was the first offender. After disabling Mylyn, all the other downstream projects also needed to be disabled because they were "directly" or "indirectly" affected by the removal of CVS and/or Mylyn.
Thanks to Jonah's analysis, most/all of the downstream projects were affected by Mylyn. Once Mylyn fixed their CVS dependency, Jonah was able to enable most/all the other downstream projects.
Sorry for the inconvenience and the alarm caused by the change!

Ditto for Modisco. My OOMPH generated Modisco installation is totally free of even transitive dependencies on CVS so there must be a fault in your dependency analysis.
Surely such a dramatic disabling should have been investigated on the Gerrit / a prvate branch and then discussed? Why was it merged to master? Why has it not yet been reverted?Regards

@Jonah Thanks for re-enabling CDO!
@Kit How did you establish that CDO depends (possibly transitively) on CVS? The bundle manifests of CDO do not contain anything to that extent, and in my target platform for CDO there are no CVS bundles.
Cheers

I have reenabled all the projects as the failures were due to transitive dependencies on Mylyn. For Mylyn I have disabled the CVS related/dependent features only. AFAICT (validation passes, waiting for full build) this should be the full solution so none of the other projects need to do anything this time.
See https://git.eclipse.org/r/c/simrel/org.eclipse.simrel.build/+/189399

It looks like we have quite a few dependencies to resolve here :-) CDT doesn't directly depend on CVS, perhaps there is a transient dependency that does though.
Does anyone know which of these directly depend on CVS? I am trying to figure it out now and hope to make a new contribution soon if possible with a smaller set of disabled projects by removing individual features.
PS Thank you for making such a large change in M1 - it gives all the downstream consumers more time to actually understand the implication of the earlier announced changes.

While contributing to SimRel 2022-03 M1 we found some projects are dependent on CVS causing SimRel build to fail. To make SimRel work we ended up disabling multiple projects. Please re-enable them once the support for CVS has been disabled. Here is the list of projects that were disabled:
- cdt
- dltk
- egit
- embedcdt
- emf-cdo
- emf-compare
- emf-parsley
- linuxtools
- m2m-atl
