---------------------------------------------

             Summary: Do not print exception when probing buildInfo.xml in remote repo
                 Key: MBUILDCACHE-32
                 URL: https://issues.apache.org/jira/browse/MBUILDCACHE-32
             Project: Maven Build Cache Extension
          Issue Type: Bug
            Reporter: Alexander Ashitkin


When cache engine tries to discover existing cache by checksum, it sends get request. 
This request is not expected to always return 200, because cache is not guaranteed to exist.
It's a normal situation and exception should not be printed in such case:
