Error reported in generating code from Ecore project which contains OCL declarations

[ASH-SYSTEMS]

Bug description

When using Ecore OCL within an Ecore modelling project (for calculating a derived attribute in one of my projects) results in an error when doing code generation for the Ecore project stating "Errors occurred while generating code." The details are in the attached file.

Everything worked fine until about April, so I guess one of the nightly builds since then introduced the bug.

Expected behavior

An errorless code generation of the metamodel.
For comparison, a native Eclipse installation generates the same project with no errors reported.

How to reproduce

1. See screenshot on how to define OCL for the Ecore
2. Generate all (from project)

Additional context

• GEMOC Studio version: 3.5.0.202204291215 and 3.5.0.202207010750
• Java version:
• OS: Windows 10

Hi
can you join a small project that produces the issue ? (a zip of the project of your screenshot ?)

as this isn't calling any GEMOC component, this is probably an installation dependencies issue
(normally GEMOC is only installing official component for OCL, but maybe we have some inconsistencies...)
