Subject Re: Gave up waiting for service" dependencies during CamelBlueprintTestSupport test of custom camel component
Date Thu, 07 Nov 2013 00:55:02 GMT
As camel-blueprint-test loads the bundle from class path to simulate the OSGi platform behaviour.
If you want to CamelBlueprintTestSupport find your custom component, you need to add the dependencies
of the customer component in your pom.
