PhpStorm: Won't receive changes of git submodule due to missing git remote

I have three projects (Main, Submodule, Test).

I added the Submodule project as git submodule in Main (which contains a lot of other code) and in Test (which is empty).

Afterwards, I make changes in the Submodule project, commit and push them.

When I press the Update Project-Button in my IDE (PhpStorm) inside the Test project, it fetches all incoming changes of the project as well as the changes made to the Submodule project.

But when I press the Update Project-Button inside the Main project, it just fetches the incoming changes to the project but won't get the changes made to the Submodule project.

git status also says that there are changes when used in the Test project but says "up to date" when used in the Submodule project

Terminal on Test project:

PS C:\Users\USERNAME\PhpstormProjects\Test> git status
On branch main
Your branch is up to date with 'origin/main'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   aar-shared (new commits)

no changes added to commit (use "git add" and/or "git commit -a")
PS C:\Users\USERNAME\PhpstormProjects\Test>

Terminal on Main project:

PS C:\Users\USERNAME\PhpstormProjects\Main> git status
On branch add-shared-repo                               
Your branch is up to date with 'origin/add-shared-repo'.
                                                           
nothing to commit, working tree clean                      
PS C:\Users\USERNAME\PhpstormProjects\Main>

Does anyone have any idea what I'm doing wrong? How can I bring the submodule up to date?

UPDATE:

I just found a difference between my two projects Main and Test.

In the Test project the "Manage Remotes"-Window looks like this:

In the Main project it looks like this:

I don't know why it wasn't added automatically like in the Test project but to all the PhpStorm people out there, does anyone know how to add those grouping to the remotes, so like in the first picture "just-a-test" and "aar-shared" above the corresponding remotes?

When I try to add a new remote manually I can just add the name (like origin) and URL.

Solution

  • UPDATE 2: Solved

    Just found it:

    In Settings > Version Control > Directory Mappings I needed to add a new entry and select the submodule folder inside the project and set "VCS" to "Git".

    Now it's working as expected just like in the Test project.
