Hi,
due to security constraints, we must carry out our development without
direct internet connections.
In the past I used Juno Eclipse SR2 with m2e 1.3and Tycho 0.16 - 0.18.
All necessary data were available on Nexus or a p2 repositories.
With the update to Eclipse Kepler and m2e 1.4 but now I have serious
internal errosr when I try toupdate / refresh my maven / tycho projects.

A similar demo project (pom same configuration) with active Internet
connection works without problems.
M2e still needs certain data at runtime from maven / p2 repositories?
Or what could be raise this error?
Thanks in advance
