Shared configuration for Eclipse on Debian server

I've manually installed the latest Eclipse on our debian server and wanted to configure it so all users share the same configuration. It turned out less obvious than I thought: I don't seem to be able to install packages for all users. If I run it myself, all configuration data is saved under my own home directory. If I run Eclipse using sudo, everything is saved under the root directory but is not accessible for other users when they run Eclipse.

I've been browsing the manual of Eclipse and some forums, but apart from a "yes, you can" I couldn't find any information on how that should be done. The biggest problem is installing plugins for all users to be found. Any help is greatly appreciated.

Eclipse : 3.6.1 classic, installed using this procedure.

Server uname: GNU/Linux *** 2.6.26-2-amd64

Server is accessed using Putty, 开发者_如何学Cand Gnome desktop through realVNC. Just mentioning it if that is of any importance. Our sysadmin is on "prolonged leave" (working in Spain and never replaced), so I'm stuck without help here.

EDIT:

I've found a list of variables that could be set in the launcher.ini or config.ini regarding configuration : osgi.configuration.area, osgi.configuration.area.default, osgi.sharedConfiguration.area, osgi.configuration.cascaded, ... But I can't figure out exaclty how to set these correctly.

-- I asked this question also on Serverfault, but I am far from certain where this belongs. Feel free to merge both questions in the appropriate place. --

For plugins, you could add in eclipse.ini (for all Eclispe you install) a common path for "shared dropins directory".
All plugins copied in that directory will be detected when Eclipse is launched.
