Hi,
we have big product where eclipse is only one piece. The
installation is modular and each piece of the big product
might come with its own plugins (or features). Those pieces
should be as self contained as possible, and therefore we
don't want the installer to "mess" in the eclipse directory.
We want eclipse (our code) to discover installed pieces. In
those pieces we might find eclipse plugins/features that should
be loaded at runtime.
Question: if we can find out the places where the plugins/features
reside, how can we tell eclipse to become aware of those plugins?
We knoe the .eclipseextension mechanism:
http://dev.eclipse.org/newslists/news.eclipse.tools/msg54812 .html
but one problem is that links have to be absolute paths:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=35037
We would like to use environment variables, java properties or
programmatically specify the paths to the installation.
Is there a mechanism to do this?
Michael

say "install me all the plugins and features from c:/").
However I'm pretty sure that the update component has something that
allows to install a feature if you tell it where it is (there is
something like that surfaced in the update UI).
As I don't know a lot about this new API, take a look at the doc. But
after giving a quick look at the APIs I would recommand you to start
your exploration by EnableCommand and other classes from this package.
If this does not help, you might be more lucky in asking your question
on platform.

ah, the specification is that we would know where to find plugins!

yes, that's what I was looking for...

I'll give it a try...
Thanks for your help

Two ways:
1. either set those locations as product extensions (an eclipse dir, with
features and plugins folders, and a marker file .eclipseextension)
and have it linked to your main eclipse via a .link file, or using the
Add site (via the update manager ui, or via command line or
programmatically)
2. use update manager and add a local site (on the second page of the
install wizard) and install from it.
