Fix CirleCI's dependency:go-offline on pom.xml version number upgrades
Fix CirleCI's dependency:go-offline on pom.xml version number upgrades

due to https://issues.apache.org/jira/browse/MDEP-516
(maybe also related to https://issues.apache.org/jira/browse/MDEP-82)

This seems to be how most projects found e.g. on GitHub
deal with this problem (search for circle.yml files containing
"dependency:go-offline", and many will have something like this).
