Developing A Rest Service Plugin

I am following the instructions given in Developing A Rest Service Plugin, here: “https://developer.atlassian.com/server/framework/atlassian-sdk/developing-a-rest-service-plugin/” to learn how to create a REST API plugin for the Atlassian Confluence project. If you look closely at the error message (see attached): “Could not transfer artifact org.apache.commons:commons-lang3:pom:3.8.1 from/to atlassian-public (https://maven.atlassian.com/repository/public)::slight_smile: hostname in certificate didn’t match: <maven.atlassian.com> != <.services.atlassian.com> OR <.services.atlassian.com> OR <services.atlassian.com>”
This states that it’s a certificate problem, and seems to be with the maven.atlassian.com site.
BUT a colleague ran the command, atlas-create-refapp-plugin, on his laptop at work and it failed. He ran it again, on the same laptop but at home and it installed OK. I have run it at work and at home with the error messages below. The fact that he got it to work at home implies to me that this problem isn’t about certificates.

Has anyone else had this problem? How did you resolve it?
