Eclipse network settings: unable to get updates

Question

When I try to install Eclipse updates or add-ons, I receive the following error message:

I'm using Debian Linux without desktop environment, I guess usually network settings are being obtained by Eclipse from Gnome or KDE global settings (however, I never used them for long enough). There are no environment variables set as for system-wide proxy settings, and the network is actually reachable for other programs.
