What causes the error in my custom module for OpenLayers 3? This error gives me a whitescreen with just this message:

Drupal\Component\Plugin\Exception\PluginException: 
Plugin (ifplabel) instance class "Drupal\ifplabel\Plugin\Style\ifplabel\ifplabel" does not exist in Drupal\service_container\Plugin\ContainerAwarePluginManager::getPluginClass() 
(line 120 of /Users/me/Sites/ifp/html/sites/all/modules/service_container/src/Plugin/ContainerAwarePluginManager.php).


Background: The name of the module is called "ifplabel". I am making a custom module for OpenLayers 3 that will provide me with a custom marker style.

Looks like a mismatch between your annotation (the @ in the comment above your class) and your class declaration. 

But you should post your code for more details.
