| Hi, Adolfo,
This is a good question for the OCL dev mailing list, so I copy my reply there. I am assuming that you are subscribed to that list ... :-)
The org.eclipse.ocl.ecore plug-in requires Ecore 2.5 because it extends the Ecore metamodel. This is a rather tight coupling with a dependency that can change in ways that are incompatible with subclasses, not to mention that the practice of extending Ecore is explicitly not supported by the EMF project. So, this is akin to using the internal API of a dependency and necessitates keeping in locked step with the dependency's version.
Can you use IMP in an Eclipse 3.4 workbench that has an Eclipse 3.5 PDE Target?
Cheers,
Christian

However if I download the version to 2.4 in the dependency all seems to work well. I suppose that the whole OCL SDK must depend on EMF 2.5 because of UML 3.0.0. But I'm not sure if the own ocl.ecore plugin must have that dependency on EMF 2.5. I suppose that it is a good policy keeping a (not too) old plugin version dependency, so that clients don't have to work with the last-in-develop component id they don't really need it. However I'm not sure about that. Do you have any advice about this ? I need to use Eclipse 3.4 while trying IMP tool (I can't use Eclipse 3.5), and I don't want to download Eclipse 3.5, EMF 2.5, etc, into my workspace If I don't really need it. And because of I only need version 1.3 of ocl.ecore (and ocl) plugin, it would be nice for me if it depended on EMF 2.4. But I'm not sure if this is a good policy... Thanks in advance for the help.
