Copy the central folder under the directory to the new workspace under the corresponding. Metadata.pluginsorg.maven.ide.eclipsenexus directory.

First check all of your dependencies including plugins and children in the dependency tree,
Try to replace snapshot versions with release versions,
As snapshot versions would always look for a later update, whereas
Release versions is deemed to be stable and updates is not expected for the same version number.

Secondly, assuming that is working on a LAN, I would suggest so you install a local MAVEN repository manager such a S Nexus, and then redirect your artifact requests by setting
<mirrorOf>*</mirrorOf>In your ${user.home}/.m2/settings.xml

This'll enable your downloads to be resolved quickly against a local mirror rather than continually checking against re Positories on the Internet.
