Re: [platform-update-dev] Update Plugin Installation Location

Isn't the answer to what you want a
feature in the target directory and all other features using the colocation-affinity
attribute?

That is, based on your post I think
your install tree looks something like this:

d:\somedir\eclipse
d:\somedir\eclipse\features
d:\somedir\eclipse\links
d:\somedir\eclipse\plugins


d:\yourproductdir\eclipse
d:\yourproductdir\eclipse\features
d:\yourproductdir\eclipse\plugins

Where in the links folder in somedir
you have a link file pointing to d:\yourproduct.

So, if you have a feature in yourproductdir
that is there already:
d:\yourproductdir\eclipse\features\your.feature

If you then added this to a new feature.xml
that was to be packaged on an update site:

<feature
      id="your.other.feature"
      label="Your
other feature"
      version="3.0.1"
      provider-name="you..."
      colocation-affinity="your.feature">

The key bit being the colocation-affinity
attribute, then all features that have this attribute will be forced into
the d:\yourproductdir\eclipse directory tree by the update manager install
wizard.

The option to choose another location
or an alternative location is greyed out.

Other products create a marker feature
in a special directory for just this reason, it lets others use that feature
id to force the install to a known target, and the product's uninstall
will NOT delete that content (as it might be needed again and it did not
write it there to begin with).  That part is not an Eclipse/Update
Manager thought, just a behavior designed into the uninstaller due to the
planned nature of that install target.

Subject	[platform-update-dev] Update Plugin Installation Location

Is there any way to specify the default location for an update plugin?
 As
a default, the wizard provides the location of the main eclipse plugins
but our product is installed under a different directory and for proper
uninstallation, the update should be under the product extension location.
(Tim Koss also brought up this issue in his post "Install/Update
questions" on May 29, 2002 and I was wondering if any changes have
been
made to accomodate this issue since then).

Thanks.
Grace
