While running
atlas-run-standalone --product jira
at work where OpenDNS is being used, I was getting this maven download error

Thanks to this article I found I wasn't alone.
I fixed this somewhat closer to the root cause in the maven-cli-plugin's pom. I located the repository declaration below and commented it out from %HOME%\.m2\repository\org\twdata\maven\maven-cli-plugin\0.6.9\maven-cli-plugin-0.6.9.pom
