Did you forget a USE statement, or did you not list all dependencies? Scrutinizer analyzes your `composer.json`/`composer.lock` file if available to determine the classes, and functions that are defined by your dependencies. It seems like the listed class was neither found in your dependencies, nor was it found in the analyzed files in your repository.
