No, I was using neither HTTPS nor a proxy authentication. It was an
http connection to the corporate nexus.
I went to copy my settings.xml to this thread, but realized that it
contained a lot of extra cruft that wasn't used anymore, extra
repositories and plugin repositories. So I reverted to the company
standard settings.xml for connection to our central nexus repository and
this made the problem go away. Strange that the previous configuration
would work under Kepler but not Luna. But it's probably better this
way. And I'm not enough of a maven-head to possibly devise a test case
for whatever condition might have caused this, sorry.
Thanks for your help. I have it working now.

It’s most likely the switch to using the aether-connector-okhttp and it not

You using HTTPS and proxy authentication? Knowing what your developer setup
with settings.xml would be useful to see. Or take a look at the test cases in
the aether-connector-okhttp code and see if your case is covered. If not see if
you can make a test that fails for your case and we’ll try to get it fixed up.

I don't see how this could possibly be the issue given my initial description
of the problem: Running from the same workspace on the same machine with
Eclipse Kepler does NOT produce the problem, yet running it from Luna DOES
produce the problem.

further info: Switching in Eclipse to use the command line installation of
Maven on my system, rather than the Embedded version default also makes the
problem go away. So the question appears to be:
What is wrong with the embedded Maven included in Luna. The working Kepler
version also uses its own embedded Maven, which does not have the problem.

Okay, that way (command line or Run As Maven - install) these errors do not
occur. But errors shown in Eclipse Luna persist.

Just try for a full build. That essentially tests the download of dependencies.
So in the project directory run e.g.
mvn clean install -U
And as a next step you can try the same in the IDE with Run As - Maven - install

Please define "it". I have no idea of what the command line equivalent is of
whatever Eclipse is doing during its automatic build.

Does it work on the command line with -U ?

The same behavior is experienced with NEW Maven projects created with Luna. They
immediately show these errors. If Luna is closed and Kepler opened on the same
workspace, and Maven->Update run, the errors disappear.

I'd been working with Eclipse Kepler. I had several Maven projects there. I
connected to Maven Central through a corporate Nexus repository. Everything
worked just fine.
Then I got Eclipse Luna and installed it. Using the SAME workspace, with the same
maven settings.xml that had the settings for the Nexus repository, I find that all
Maven projects show errors that cannot be resolved by running Maven->Update.
All mention something about connections being refused by Maven Central.
I closed Eclipse Luna and restarted Kepler on the same workspace. (I was never
running them simultaneously). The same errors appeared, but now Maven->Update
was successful in resolving them.
I closed Kepler and restarted Luna on the same workspace. Once again, the errors
returned, and were not resolvable by Maven->Update.
Here is one of the errors:
CoreException: Could not get the value for parameter compilerId for plugin
execution default-compile: PluginResolutionException: Plugin
org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies
could not be resolved: The following artifacts could not be resolved:

was cached in the local repository, resolution will not be reattempted until
the update interval of nexus has elapsed or updates are forced. Original error:

(http://mavencentral.it.whatever.com:8084/nexus/content/groups/whatever-public-group):
Connection refused: connect
What might the problem be?
