Probably a typo.

So why is it called ENVIRONMENTS instead of just ENVIRONMENT? Are there future plans to support several?

Hi Helmut,
Thanks. But that approach will not help me. I cannot ask all the Buckminster users to modify their UI's. I would need a meta-data repository scrubber or something to get rid of them (horrible thought) :-)

Pascal, what will happen if I add many different environment combinations to the

PROP_ENVIRONMENTS

(the plural form suggests that this is possible). Will that make the profile accept all IU's that match at least one of the environments listed?

Regards,
Thomas Hallgren

Hi Thomas :) A while ago we asked for the filters to be able to support multiple values, I think I remember having filed a bugzilla for that .. *searching for the number* The way we do it right now is to have our IUs not specify any osgi.os filter as a condition so that p2 has no knowing of what os the IU was meant for...

I understand the issue with platform specific install handles, etc. But you seem to have cracked my problem. How do you avoid "osgi.os"? Do you simply skip the PROP_ENVIRONMENT setting in the profile? Regards, Thomas Hallgren Haigermoser, Helmut wrote: Ciao Thomas :) Our p2-based installer does the same, it installs IUs for every platform into a single profile. We need this to support multi-OS installations. The way we do it is to avoid osgi.os... Like Pascal said there are limitations, installing the IU containing "firefox.exe" on linux will be OK but the associated Start Menu entry for windows can't be registered etc. Another idea is to use layers of profiles, one per osgi.os, or some form of local profile that would look at the IUs in the central profile and execute all Start Menu creation etc. for the local host...

Subject: 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.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? Regards, Thomas Hallgren _______________________________________________ p2-dev mailing list
