Description David Williams CLA 2010-11-30 04:29:53 EST 
I'm opening this enhancement request as a result of issues 
and discussion in bug 331061. 

There, there is an issue that a platform filter of "required" feature, doesn't match that of the feature that requires it (the requiring feature does not have a filter, the feature it requires does). In b3 aggregator, the only message available is, basically, 

Missing requirement: org.eclipse.gyrex.features.sdk.feature.group
1.0.0.v20101124-1920-7L--F9kw82d1TXvQlFnX0fCz-G1k requires
'org.eclipse.gyrex.features.kernel.source.feature.group
[1.0.0.v20101124-1415-7A--F7RZHQHQQO-8OlhR]' but it could not be found
 
But the version does exist, just not for all platforms. 

So, the message would ideally say "abc requires xyz, but it could not be found for the LMN platform" or similar. 

As it is, it is very hard to track down the problem. 

And, don't get me wrong, I'm not asking for detailed (cryptic) message ... even if it didn't mention a specific missing platform, and simply said "abc requires xyz, but it could not be found for required platform" that would at least give a hint there was more than just a feature/version issue going on. As it, no one thinks to consider platform (or other filters?) in diagnosing the problem.

Frankly, a little bit of additional detail is necessary. In the specific case the required platform was "ANY". A user reading that message needs to understand that "ANY" does not mean _any_ but _without-platform-filter_.
Comment 2 Pascal Rapicault CLA 2010-12-23 19:18:49 EST 
The problem here is that the IUs are not being picked because they are removed from the set of IUs being considered. Consequently I'm not quite sure what we can do.
Could you please provide a simple sample reproducing the pb. Thx.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
