Description Steffen Pingel CLA 2010-06-15 18:15:14 EDT 
I have installed several features from http://download.eclipse.org/webtools/repository/helios . If I now select the WST Web Plug-in Developer Resources feature from the same repository the installation fails with a P2 error:

Cannot complete the install because of a conflicting dependency.

Comment 1 David Williams CLA 2010-07-28 17:00:08 EDT 
I've not yet tried to literally reproduce, but I've looked in detail at and for the org.eclipse.wst.web_ui.feature. All I see on file system of any repo is version

3.2.0.v201005241510-7O7CFb3EMf84nP-FHuc10NTz--M3

but never 

3.2.0.v201005241510-7O7CFb3EMf84nOyJKuT05LU72RId

Either on file system, or in any feature.xml file. 

Are you sure you didn't start off with an early version? A few days before release, perhaps? Did you start off with any particular distribution that might have included it? (php? jsdt?) [I checked only JEE package distribution]?
Comment 2 Steffen Pingel CLA 2010-07-28 17:55:03 EDT 
It's likely that I had originally installed features from the Helios repository and then added the webtools repository later. I assumed that these repositories would be compatible, i.e. I could get a base webtools distribution from Helios and then add developer features from the webtools repository. Is that not necessarily the case?

They should be compatible ... and I checked features from Helios site, and there saw only the 3.2.0.v201005241510-7O7CFb3EMf84nP-FHuc10NTz--M3 version on the actual file system. I'll give it a brief try and see if it works, but my guess is I won't be able to reproduce the problem, and may have been due to exact timing of when you got things installed (i.e. installed slightly before the official release). But even then, not sure why it wouldn't to ahead and install the "final" versions on top of the earlier ones, so may also depend on some subtle sequence of steps.
Comment 4 David Williams CLA 2010-07-29 03:28:33 EDT 
I can't reproduce. I tried several scenarios, and all seemed to work as expected. If when you see again, please try and document exact steps, as it might be related to that. 

Thanks for reporting.
