Maybe you did not declare it correctly or list all dependencies? The issue could also be caused by a filter entry in the build configuration. If the path has been excluded in your configuration, e.g. `excluded_paths: ["lib/"]`, you can move it to the dependency path list as follows: filter: dependency_paths: ["lib/"] For further information see https://scrutinizer-ci.com/docs/tools/php/php-scrutinizer/#list-dependency-paths Loading history...

		0 ignored issues – show Bug Best Practice introduced 2022-12-29 11:17 UTC by Report Bug Copy Issue Report The expression `return $this->start + $index * $this->step` returns the type `integer` which is incompatible with the return type mandated by `Smoren\Sequence\Interfac...face::getValueByIndex()` of `Smoren\Sequence\Interfaces\T`. In the issue above, the returned value is violating the contract defined by the mentioned interface. Let's take a look at an example: interface HasName { /** @return string / public function getName(); } class Name { public $name; } class User implements HasName { /* @return string\|Name */ public function getName() { return new Name('foo'); // This is a violation of the ``HasName`` interface // which only allows a string value to be returned. } } Loading history...
