I've checked the META-INF/services folder and it only contains this file : org.jclouds.logging.config.LoggingModule
However the bundle activator is scanning for "/META-INF/services/org.jclouds.providers.ProviderMetadata" . My main question should be if I create a new Provider, how will I make sure it gets registered in OSGi?
