Description Michal Tkacz

Build Identifier: I20100429-1549

When I try to provision target platform using certain update sites, Eclipse fails to find  plugins, showing only "0 plug-ins available". In particular I experience this problem with two update sites produced with Hudson at build.eclipse.org:
https://build.eclipse.org/hudson/job/emf-cdo-integration/lastSuccessfulBuild/artifact/result/site.p2/
https://build.eclipse.org/hudson/job/emf-cdo-maintenance/lastSuccessfulBuild/artifact/result/site.p2/

Note that I can use the same two update sites to provision Eclipse itself, without problems.

Reproducible: Always

Steps to Reproduce:
1. Go to Window | Preferences to add a new empty target definition.
2. To the list of locations add new software site: https://build.eclipse.org/hudson/job/emf-cdo-integration/lastSuccessfulBuild/artifact/result/site.p2/
3. Choose "Net4j Signalling Platform SDK" feature (or any other) and uncheck "Include required software".
4. Click Finish. "0 plug-ins available" will be displayed next the software site address.

Reproduced, I will debug through it when I get a chance.  Only thing I noticed was that if you set "include required software" the provisioner is unable to find a required bundle in the repository.  If "include required software" is turned off, the slicer will try to get all available requirements, but because some plug-ins are missing it may not be including everything.  This could be a problem with the repository.

I'm not sure what has changed, but it works for me now.

I observed similar behaviour in the target editor several times. My workaround: check the flag "Include required software", confirm, uncheck the flag, confirm.
