Helidon quickstart Docker build not finding parent specified in pom.xml - docker

Question

When I build the example in Maven it works fine; however when I try to do the docker build, it errors out. Has anyone else come across this or have a fix? I can build other docker images just fine. thanks in advance.
Here is my command line build results:
S:~/eclipse-workspace/helidon-quickstart-se$ docker build -t helidon-quickstart-se .

I may be missing something, but isn't this simply a very basic problem with your connectivity to Maven Central? From the stack trace you posted:
Could not transfer artifact io.helidon.applications:helidon-se:pom:2.4.2 from/to central (https://repo.maven.apache.org/maven2): Transfer failed for https://repo.maven.apache.org/maven2/io/helidon/applications/helidon-se/2.4.2/helidon-se-2.4.2.pom and 'parent.relativePath' points at no local POM # line 7, column 13
But, as you can see, of course, the artifact most certainly does exist. Perhaps whatever is doing the fetching is behind a network proxy?
