I created 2 more modules and did like below:

```
"autoload": {
        "psr-4": {
            "Application\\": "module/Application/src/",
            "Admin\\": "module/Admin/src/",
            "User\\": "module/User/src/",
            "Vendor\\": "module/Vendor/src/"
        }
    },

```

But only last vendor module is working, and other two user and admin module are not working. So is that i will require to create different autoload snippet for admin and user module and add in composer.json ?
