Re: [p2-dev] Platform agnostic profile

Ok, let's step back. Even if you were able to resolve, doing an actual installation of all the IU is impossible since there will be actions that are platform specific that can't be successfully run (e.g. window registry key setting on a linux box).
>From a java world perspective when it comes to building, the only thing that is necessary is to have access to the jars, however the jars in the repos are not necessarily in a runnable form (e.g. they can be packed or they can be in jar where they need to be a folder form) and they need to be massaged. The code we introduced in M5 (org.eclipse.equinox.p2.repository.tools) goes over a set of repositories and "massage" the artifacts and the resulting massaged artifacts are then passed to PDE Build as a target. Again this work at the artifact repo level and as such does not consider the metadata dependencies (https://bugs.eclipse.org/bugs/show_bug.cgi?id=264267) which is why it can be of help.

I want to create a target platform (or product) that can be used cross-platform. I'm not sure how massaging repositories can make that happen. Is the PDE build removing platform constraints from the IU's before installing them?

In M5 we have released support for PDE build to use as a target p2 repos and also fetch from p2 repos. These repos are massaged by PDE to make the plug-in available in a "compilable" form. This is probably what you are looking for.

I need it to create a target platform that can be used for building products that can run on all platforms. It is essential to us (and everyone else that creates similar products) that the platform based discrimination is performed by OSGi at runtime and not at install time.

It is not possible to create such a profile. This would require changes into the slicer to ignore the filters (should be straightforward) but the hardest part would be in defining what is a valid solution since there could be several singletons that would need to be enabled.
What would you use this profile for?

I would like to create a platform agnostic profile. I.e. a profile that
would accept IU's regardless of platform filters. The analogy (which I
think is impossible at present) would be to describe the current
delta-pack as a feature and install it so that all it's bundles are
installed.

Is it possible to create such a profile? Can the PROP_ENVIRONMENT accept
wildcards?
