How to use UML2 with Maven [message #1733341]

Dear all,

I would like to generate sources from my Xcore model that references UML elements. I use the maven-xtext-plugin that does not use p2 repositories but maven dependencies for gathering dependencies. This approach works well for Xcore models that do not have a dependency to UML models.

My goal is to simply add the dependency to org.eclipse.uml2:uml:5.0.0-v20140602-0749 (http://mvnrepository.com/artifact/org.eclipse.uml2/uml/5.0.0-v20140602-0749). Unfortunately, this depends on org.eclipse.emf:ecore:[2.10.0,3.0.0), which is not available from maven central. Therefore, it is not usable from plain maven.

In contrast, org.eclipse.emf:org.eclipse.emf.ecore is available from maven central with the corresponding version. Because of the different artifact id, maven does not resolve to this.

How do I work around this issue or is this just a bug that should be fixed?

Best regards
Stephan

I found the Eclipse Nexus repository, which contains some bundles. However, the codegen bundle is missing, for example. In the central maven repository, there is a quite old version. Are there any plans to add these bundles to Nexus as well?

Hi

My understanding is that provision of sensible Maven distribution awaits
support from Eclipse IT and that it is dependent on resolution of
incompatible version/persistence policies wrt Eclipse and Maven repos.
However since some projects seem to do it, maybe it is just necessary to
tell the rest of us what to do. Certainly I have done, and plan to do,
exactly nothing until someone tells me what to do for OCL. I suspect the
same goes for UML and EMF and ...

Hello Ed,

while your answer is perfectly reasonable, it is a bit disappointing as well. So, for the short term, there seems to be no solution.

I will look into the generator plugin for Xcore in more detail to determine if I can work around this issue.

Thanks
Stephan
