I am currently developing a plugin for Cameo Systems Modeler 2021x using IntelliJ IDEA.

I am encountering an issue when I include simulation_api.jar in my project : when I run my plugin in IntelliJ, Cameo Systems Modeler fails to launch the Cameo Simulation Toolkit, and I receive the following errors:

java.lang.NoClassDefFoundError: com/nomagic/magicdraw/simulation/gui/b/c

followed by

java.lang.ClassNotFoundException: com.nomagic.magicdraw.simulation.gui.b.c

Interestingly, when I do not include simulation_api.jar, this error does not occur. However, I need simulation_api.jar for my project, and I also require the Cameo Simulation Toolkit to launch correctly.

I would greatly appreciate any assistance or guidance on how to resolve this issue. Thank you!
