If you want the Jar file to be included in your application, you'll need to add the jar file to the userlib folder. The folder lives in the root directory of your project. You can find the root directory of your project from Studio Pro under App->Show App Directory In Explorer.  Add the jar file here to the userlib folder. It's also common practice to add an empty txt file, with the same name as the jar, along with the module name that requires that jar file. I can't speak to if this will solve your problem, but hopefully it'll help you make some progress.
