Re: [platform-dev] recommended way placing the workspace relative to the

[Christoph Läubrich <laeubi@xxxxxxxxxxxxxx>]

Yeah I have checked the help, but sometimes there are "hidden 
options"... but it seem no luck here :-)

My use-case is to have an "portable" eclipse based application, so I can 
plug in the device and have a (default) workspace with my 
projects/preferences and so on.

So the very fist thing would be e.g. to have an eclipse that uses a 
default workspace that is placed alongside the installation and I can 
change preferences or create a plain (empty) project.

If that basic thing would work, the next step might be to convince other 
projects (like JDT, m2e ...) to support relocatable workspaces, so one 
might think to even place JDKs, ant and maven installs and so on on this 
usb-device so I just need to plug it into any PC and could start working.

The Gerrit change looks promising, not sure how much work it would be to 
extend this to other locations as well? It seems to use a property 
'PROP_LAUNCHER' so it seems possible as its done with @user.home ...?
