Re: [equinox-dev] [p2] How to use director/mirror app against an RCP as

[Carsten Reckord <reckord@xxxxxxxx>]

Have you tried something like this?

$ ~/ profiles-ide/eclipse/eclipse.exe -application org.eclipse.equinox.p2.director -metadataRepository file:/C:/Users/creckord/profiles-ide/eclipse/p2/org.eclipse.equinox.p2.engine/profileRegistry/D__data_profiles_installations_profiles-ide_eclipse.profile/ -artifactRepository file:/C:/Users/creckord/profiles-ide/eclipse/ -destination C:/Users/creckord/git/profiles/tmp -installIU org.eclipse.core.runtime

It works for me. The Eclipse installation folder (or your bundle pool) has an artifacts.xml and can act like a regular artifact repository. You might run into some strangeness with features and product IUs though, since they aren't preserved 1:1 in their original form (features are usually extracted, but P2 will rebundle them on the fly for you; I don't quite remember what the situation was with products, but I've run into some repackaging issues way back in the Buckminster days)
