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...

			1 ignored issue – show Bug introduced 2019-10-07 10:28 UTC by Report Bug Copy Issue Report Are you sure the usage of `$this->get($name)` targeting `Phoole\Config\Config::get()` seems to always return null. This check looks for function or method calls that always return null and whose return value is used. class A { function getObject() { return null; } } $a = new A(); if ($a->getObject()) { The method `getObject()` can return nothing but null, so it makes no sense to use the return value. The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes. Loading history...

			0 ignored issues – show Documentation Bug introduced 2019-10-07 10:28 UTC by Report Bug Copy Issue Report It seems like `$this->loader->getTree()` of type `Phoole\Base\Tree\Tree` is incompatible with the declared type `Phoole\Config\Tree` of property `$tree`. Our type inference engine has found an assignment to a property that is incompatible with the declared type of that property. Either this assignment is in error or the assigned type should be added to the documentation/type hint for that property.. Loading history...
