I'm not sure if this is a maven dependency issue. Any help would be appreciated............................................................................................................

The error is returned by a Jenkins instance. There is nothing generated by Mule in that error. You are either calling the wrong server or the Mule application is just a proxy to Jenkins. Either way the error is in Jenkins and you need to investigate what Jenkins is doing.
