Why does the ZF2 autoloader build the path wrongly?

Question

I have an application with some modules. One of them is CourseSearch. Now I want to add a further one, the SportsPartnerSearch. Since these two modules are very similar to each other, I simply "cloned" / copied the CourseSearch and replaced all "Course" with "SportsPartner" (in all variations: $course to $sportsPartner, course-...phtml to sports-partner-...phtml etc.), in order to edit the logic in the second step. Now I'm getting following errors:

Warning: require_once(/path/to/project/module/SportsPartnerSearch//src/CourseSearch/View/Helper/CourseSearchForm.php): failed to open stream: No such file or directory in /path/to/project/vendor/zendframework/zendframework/library/Zend/Loader/ClassMapAutoloader.php on line 140

Fatal error: require_once(): Failed opening required '/path/to/project/module/SportsPartnerSearch//src/CourseSearch/View/Helper/CourseSearchForm.php' (include_path='.:/usr/share/php:/usr/share/pear') in /path/to/project/vendor/zendframework/zendframework/library/Zend/Loader/ClassMapAutoloader.php on line 140

Why is the path to the file being built in such strange way: /path/to/project/module/SportsPartnerSearch//src/CourseSearch/View/Helper/CourseSearchForm.php? Where did I do a mistake?

Some additional information.

The class, that cannot be found because the wron path is CourseSearch\View\Helper\CourseSearchForm in the CourseSearch module. It can be found, when I deactivate the new module SportsPartnerSearch, that contains the class SportsPartnerSearch\View\Helper\SportsPartnerSearchForm.

The CourseSearchForm view helper is instanciated in the CourseSearchForm\Module

class Module {
    public function getViewHelperConfig() {
        return array(
            'factories' => array(
                'courseSearchForm' => function($serviceManager) {
                    $helper = new View\Helper\CourseSearchForm(array('render' => true, 'redirect' => false));
                    // ERROR. This code is not executed anymore.
                    $helper->setViewTemplate('course-search/course-search/course-search-form');
                    $courseSearchForm = $serviceManager->getServiceLocator()->get('CourseSearch\Form\CourseSearchForm');
                    $helper->setCourseSearchForm($courseSearchForm);
                    return $helper;
                }
            )
        );
    }
}

And called in the layout file:

echo $this->courseSearchForm();

The SportsPartnerSearch\View\Helper\SportsPartnerSearchForm is instanciated in the same way in the SportsPartnerSearch\Module#getViewHelperConfig() and is not called yet.

Have you generated a classmap? Check the autoload_classmap.php file in both the CourseSearch and the SportsPartnerSearch modules. I guess you still have an old classmap lying around. I think the problem is hidden inside the classmap because of the error in the ClassMapAutoloader from Zend, and not the standard autoloader.

You can generate a new classmap with the classmap generator provided in ZF2 (assuming you load it via Composer) with:

cd module/SportsPartnerSearch
../../vendor/bin/classmap_generator.php

This will generate a new classmap file inside the SportsPartnerSearch module.
