Certificate for coderplus.com has expired > 53 days ago

[dashorst]

My Eclipse installation is complaining about the expiration of the coderplus.com certificate, and refusing to update the maven-remote-resources-plugin (or concluding that no update is necessary).

And when trying https://coderplus.com my browser also complains about the expired certificate. As the other maven plugins are now available from coderplus.io, is it a possibility to also serve the maven-remote-resources-plugin from that update site?

Same problem here with Axis2-builds. As the currently used certificate is from Let's encrypt already, maybe fixing the automatic update setup is even easier than migrating things.
