Re: [p2-dev] Asking for advice from p2-experts

I was just trying to install the core pieces which is why I did not see the error.

I can now get the same error and the message indicates that you are looking for a core feature whose version should be [1.0.0.qualifier, 2.0.0). The problem is that 1.0.0.2010 is smaller than 1.0.0.qualifier and as such the dependency can't be satisfied. So the resolver and the error messages are correct.
Now what is suspicious is that your metadata still contains ".qualifier" whereas this should have been replaced at build time, and this is caused by the incorrect use of "qualifier" in the import statement of the feature which is not replaced at build time
<requires>
<import feature="org.eclipse.ufacekit.core.feature" version="1.0.0.qualifier"/>
</requires>

So there are two solutions:
- Include the core.feature in the ui.feature and continue on using the qualifier
- Keep the current structure and remove .qualifier.

Hi Pascal,

Sorry to bother you once more but I just tried this myself with 3.5.1 on
OS-X but I'm failing there as well but with a completely different error.

The installer UI tells me:
------8<------
Cannot complete the install because one or more required items could not
be found.
 Software being installed: UFK - UI - Feature 1.0.0.201001261804
(org.eclipse.ufacekit.ui.feature.feature.group 1.0.0.201001261804)
 Missing requirement: UFK - UI - Feature 1.0.0.201001261804
(org.eclipse.ufacekit.ui.feature.feature.group 1.0.0.201001261804)
requires 'org.eclipse.ufacekit.core.feature.feature.group
[1.0.0.qualifier,2.0.0)' but it could not be found
------8<------

To me those "feature.feature" entries look strange.

My process was the following:
* I downloaded the zip
* unzipped
* Add an Software site pointing to the directory
* Selected all features

So I wonder how you managed to install it, same error message I get on
3.6M5 too.
