Execution default of goal com.smartbear.soapui:soapui-maven-plugin:4.6.1:test failed - maven

Question

Our SOAPUI test project has recently started failing with the message:

We havent made any changes to it for weeks but now Maven cannot find a couple of JARs.
The pom.xml is:

I guess SmartBear has changed their Maven repos, is there a way to fix this?
Our project is on a GitLab CI / CD pipeline using a Maven Image, we have tried directly on GitLab.com to eliminate our network and it still fails there.
