Answer 1

Couple of things to try:

1. Doublecheck the location of the local artifact repo configured in your settings.xml file (at the following location {your home folder}/.m2/settings.xml). Are you sure the local repo is where you think it is? (Yes, a mistake I've made in the past...)
2. Remove entire contents of artifact repo on the new build machine (or at least anything related to Maven). You mentioned doing some artifact repo cleanup but I'm not sure what directory(ies) you removed. I've run into weird issues like these when a jar was corrupted.
3. Make sure you have enough disk space/quota for the local artifact repo. I have run into weird issues when I didn't have a large enough quota to hold all the artifacts, likely caused by partially downloaded jar files.
4. Try running with plain Maven on the command line; take Eclipse and m2e out of the equation. mvn -U dependency:resolve should do it. The -U forces Maven to download no matter what your repository update policies are. Add -X to get detailed debug logging.
5. Copy settings.xml from MAVEN_HOME\conf\ to USER_HOME.m2. Add proxies (if needed) in case you are behind a proxy server.
