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:

of its dependencies could not be resolved: The following

reattempted until the update interval of nexus has elapsed or
updates are forced. Original error: Could not transfer artifact

What might the problem be?
