I am new developing plugins in eclipse, I am working with SysML models in papyrus. When I run the plugin as an eclipse application I get some errors. Despite the errors, the plugin works as intended. I would like to know how to solve them. I think that they are related to the dependencies and runtime variables but I don't know what I am doing wrong. Thank you in advance.
The errors are the following ( when running the project as an eclipse application)
