Re: [tycho-user] Building an update site for multiple OS/WS/Arch combinations 
Hi Marcel,

As for the RCP example, I believe if you remove the tycho-p2-director-plugin from the example update site project that it would build a repository just with the plugins and features that are defined inthe category.xml. I believe it is the materialize-products goal that downloads all the extra dependencies into target/repository that are required for the RCP to run.

Two other things that may be causing issues:
1) Are you building your update site in an aggregator build along with your plugins and features? It needs to be, otherwise the update site project won’t know where to find the features/plugins.
2) Does your target-platform-configuration in your POM declare all three environments (see the parent POM of the RCP example)?

Regards,
Daniel
