Correct way to set project file path for WsdlProjectPro in composite project

hi,

i'm working with a composite project and I'm trying to declare the project variable as mentioned on the docs (under Workspace-related scripts) but I'm not sure on which file path I'm supposed to put in

code from docs:

import com.eviware.soapui.impl.wsdl.WsdlProjectPro

WsdlProjectPro project = new WsdlProjectPro("The full path to the project file")

 I tried the following:

• using the file project.content
• using the project folder path

neither of those work, so, which is the correct path I need to put in?

also, this is the current path of the project folder:  C:\git\TestProject

Thanks!😀
