Does not add paths to subfolders when packaging toolbox

Hi,

I'm currently having an issue when trying to package code into a toolbox. I select the main code folder in the tool and it shows all the subfolders present. However, when packaging it up and installing it, it only adds the path to the main code folder and not the subfolders, hence it cannot find most of the code.

This has not been an issue with previous versions of the toolbox that was made by a collegue. I have tried creating the package from scatch again, rather than the save toolbox.prj file and still the same thing occurs (also tried window / mac version both 2019b, 2020a and 2020b but no luck).

I understand that I can add the subfolder manually afterwards, but as the toolbox is to be distrubuted it would be nice to have this automatically done when the toolbox is installed, and given the fact that it worked before without.

Any help would be apprecieated. Thanks in advance.

What code in the "main code folder" calls the code in the subfolders? Does it only access the code in the subfolders because those subfolders contain class definitions and it loads objects of those classes from MAT-files using load?

Hi Steven, thanks for your reply.

The classes in the subfolders are designed to be called independantly of the code in the main (top level) folder as such, and called directly from the users project. The code in the main folder is essentially a few example test scripts to show how the code would run in a project, and create objects from the classes in subfolders. None of the classes in the subfolders directly 'load' data from a .MAT file, but the test scripts do. Essentially, from the users perspective, they would create objects from the classes in the subfolders, nothing from the main folder. Hope that makes some sense.

While I could just remove the subfolders and have all the code in one folder, this would make things very messy, and as said this has worked fine before.

I am facing the same situation, My toolbox consists of 3 subfolders with different scripts and files, the user should just be able to call them directly after installng the toolbox but the only folder added to the path is the top folder, so the files and subfolders are not existing in the path.

Found the fix: When packaging the tool you need to go to the 'Install Actions' section, then click on 'Manage the current MATLAB Path', look for the top folder where the subfolders are located, select it and click on 'Add with subfolders' on the left side, then close the path window and your tool should have the subfolders now.
