Michael,

Actually I was in the releng guy in the OCL team before recently. Unfortunately, I won't be able to help you with U2T because my current schedule at Eclipse is rather unstable.

As I know the common modeling build releng procedure which is used in U2T has not been changed. Thus, you should be able to build your project the way you did it for Galileo. However, you have to manually start a promotion script from your ssh console to publish your build. Do you have problems building U2T or publishing its builds?

Cheers,
- Alex.

Hello,

In its actual state in the repository the U2T should not have any dependencies to outdated components in general and to emf.ocl in particular.
It had been regenerated with the release version of the GMP-tooling and has remarkable number of fixes and improvements from the 0.9.0 release.
It also had been locally tested against the Helios and _should be_ compiliable and installable over the Helios modeling package.

It's a pity, because I don't have basically any idea on how to make a build either at http://modeling.eclipse.org/modeling/mdt/uml2tools/build/ or from somewhere else.
I have to admit that building always had been a real trouble for me, so that's very probable that I am (for a couple of months at least) struggling with something really simple.

Ed, do you think someone from OCL team (may be the one who was responsible for your builds) can take a look at the U2T build? 
I would appreciate any help, and really hope that it should not take much time/efforts.

Regards,
Michael

Hi Ed, Kenn,

I hope the situation with UML2Tools is not that dramatic. I think we should start with asking Michael whether the problem can be fixed on their side.

Cheers,

Hi Kenn

UML2-Tools fell off the Helios train, and Papyrus is not yet ready to replace it.

Users therefore need to run the Galileo release on Helios, but the Galileo release has a spurious dependency on org.eclipse.emf.ocl 1.x that was deprecated and so removed from Helios. Installation fails.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=318941 provides a workaround.

Since UML2-Tools is unlikely to rebuild, it would be nice to include the workaround in MDT/OCL 3.0.1, but any compatibility org.eclipse.emf.ocl should be 3.x so UML2-Tools installation would still be broken.

Is it permissible to have beyond end of life 'compatibility' releases that totally break API contracts thereby allowing the org.eclipse.emf.ocl 1.4.300 workaround in MDT/OCL 3.0.1?
