check [Solved] modelio.core: The 'Infrastructure.Abstraction' metaclass does not exist

3 months 1 week ago - 2 months 3 weeks ago #5664 by lmichel
Modelio 3.8 / unbuntu 16.4

I do not manage to add either notes or constraints in my classes.
When I look at at the console, I got this error:

2019-06-14 13:38:49,872 WARN modelio.core - 'Trace'{b629524d-9688-4d1c-b197-6fd372308cdf} Infrastructure.Stereotype: The 'Infrastructure.Abstraction' metaclass does not exist.

When I scan the jar files in the distrib, I found one with the missing class:

plugins/org.modelio.metamodel.emfapi_3.8.1.201902151006.jar

Any idea to fix this issue?

I think that the ModelerModule is not correctly installed in your project. Can you click on the Configuration/Modules... menu and check the content of the Project's modules section. Which is the status of the Modeler Module? And which version is indicated?

Modeler module 9.0.07, seems to be OK.
I've been investigating furher on my side, and it appears that the bug occurs for one specific project built on a generic template we are using in our collaboration. That template seams to break something in Modelio. Any idea to go ahead?

After further investigations, it turned out that the import of the template we are using was in failure.
The issue can be closed.
