Can't find a schema location for the amqp:outbound and amqp:inbound endpoints anymore

Hey, guys!

I've started to get the exception for the flow, which used to work couple of days before. The flow is:

Have you changed anything is the schema location so far?

I need the help from you urgently.

Thanks,
Laura.

check that you have the amqp connector in your maven pom. you are probably missing that library
