  • Is it possible to retrieve the path of the currently open project?

    I would like to retrieve the path of the currently open Burp Project to reference some resource on the filesystem relative to the project directory. I am unable to find a suitable API to do this in the documentation. Is it currently possible to do this? If not is it possible to add an API for it?
