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:

What might the problem be?
