Using links file with p2 [message #120865]

I am trying to add a feature to Eclipse 3.4 using links mechanism.
The folder I am trying to add is having a feature with two different
versions. Similarly the plug-ins folder also has two sets of same
plug-ins with different versions corresponding to the two features (same
feature of two different versions).
On starting Eclipse 3.4, with a link file in links folder pointing to
the above mentioned setup, latest version of the feature is getting
loaded, but some of the plug-ins of older version are getting loaded.
The set of plug-ins getting loaded with older version is not consistent
every time I restart eclipse with clean option.
The same setup works fine with older version of Eclipse.
Is the setup mentioned above a valid one in Eclipse 3.4? Can I
explicitly specify Eclipse to load a certain version of plug-ins?

You'll want to move your .link files into dropins/.

I've tried using dropins also, but had no luck. Even with the dropins
folder also the behavior is same.

What's in your dropins/*.link files? Can you post a sample?

Can you remove the old versions, either by deleting/moving them out of
eclipse/plugins and eclipse/features, or by removing the .link file that
references them, or by using p2's Help > Software Updates... Intalled
Software (tab) > Revert Configuration... (button) ?

Have you tried restarting Eclipse with the -clean flag? Or debugging
using the osgi console (start with the -console flag) ?

The link file contains the following content:

--------------------------------
//Point to the path variable the parent location of eclipse folder
//which hosts plugins and features
path=D:/ganymede/addons
--------------------------------

And the add-ons folder contains the plugins and features in the following
structure.

addons
+---eclipse
+----features (has a feature with two versions)
+----plugins (has all the plug-ins of two versions)

When I tried having plug-ins of only one version in the linked folder,
everything works fine.

If this workaround isn't sufficient and you feel that p2 is selecting
the WRONG version of a plugin (generally, it's the latest / newest),
please file a bug in RT.Equinox.p2.

One way to pick a specific version would be to uninstall all versions,
then pick one by hand to install. Of course if you're using .link files
you don't get this granularity -- p2 does its own thing when using the
old .link approach.
