Why is artisan make:controller not making controllers?

$ artisan make:controller fooController
Controller created successfully.

A controller is not created under app\Http\Controllers and git status does not show any changes. Running the command a second time returns "Controller already exists!" artisan make:model Foo works fine as does creating a controller by hand, but that's not really fun. What am I missing?

    "php": ">=5.6.4",
    "laravel/framework": "5.4.*",

The workstation is Windows and there do not seem to be any permission problems.

Edit: Tried running composer update, same result.
