What are some potential issues when using Composer with a specific file structure like the one described in the forum thread?

One potential issue when using Composer with a specific file structure is that Composer may not be able to autoload classes properly if the namespace does not match the directory structure. To solve this, you can specify the PSR-4 autoloading standard in the composer.json file to map the namespace to the correct directory. ```json { "autoload": { "psr-4": { "App\\": "src/" } } } ```
