Documentation Bug introduced by
It seems like $composer->getConfig() of type object<Composer\Config> is incompatible with the declared type object<Composer\Composer\Config> of property $config.

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..

The method getRepositories cannot be called on $this->package (of type array).

Methods can only be called on objects. This check looks for methods being called on variables that have been inferred to never be objects.
