Hi,
If you use the shared configuration (hgschmie) or you don’t have the write permission on Eclipse/MyEclipse home (dsurber), every user have to use a separated Eclipse configuration.
You can do this using next option:
-configuration ~/myconfiguration
You also have to have the write permission on the configuration directory (~/myconfiguration).
When you start Eclipse with this option the first time, you will have to configure MyEclipse (and other plugins that are out of the Eclipse home directory). After configuring, you will work regularly(without restarting). Every user have to configure MyEclipse once, because the users share plugins, but they configure them separately.
Regards
