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:

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

org.apache.maven:maven-plugin-api:jar:2.0.9,

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: Could not transfer artifact
org.apache.maven:maven-plugin-api:jar:2.0.9 from/to nexus (http://mavencentral.it.whatever.com:8084/nexus/content/groups/whatever-public-group):

What might the problem be?
