I want to include a feature and it's plugins in my product.
The feature and plugins are stored into a .jar file on artifactory.
Also, the .jar file doesn't contain a p2 update site, but a classic (3.4 style).
The structure of the .jar containing the resources is:
- .
---- features/
------- my.feature_1.0.0.20110511-1514.jar
---- plugins/
------- my.plugin_1.0.0.20110511-1514.jar
---- MANIFEST.MF
My questions are:
First of all, is it possible to use Buckminster to import from this source even by developing some sort of resolver or extending a reader type?
Is it possible to chain the resolvers somehow. For example:
Use a p2SiteGenerator reader which uses a zip reader which uses an artifactory reader?
What would be the best practice for doing such chaining (importing stuff into the workspace as well as in the build)?

Yes, you can probably do that out of the box using a url reader type with a matcher (to extract names and versions from
file names).

Yes, either put them both in the same provider (best fit wins) or put them in separate providers and use locators with
failOnError=false (first fit wins).

I would never import binaries into the workspace. Put them in he target platform.

Actually, after looking closer at the content of the .jar file, the exact structure is:
---- features/
------- my.feature_1.0.0.20110511-1514/
---------- feature.xml
---- plugins/
------- my.feature.plugin1_1.0.0.20110511-1514/ (and subfolders)
------- my.feature.plugin2_1.0.0.20110511-1514.jar
---- META-INF/MANIFEST.MF
So it's an "ancient" feature (that is used by another 3.4 build).
Can the p2 reader be used on the folder structure above?
Can I import that into the target platform?
Also, by chaining, what I meant is for the output of the first reader to be used as input for the second reader and so on.
In my case, my problem is exactly this:
The maven2 reader should output the jar file containing the above structure, then a url.zipped reader should use the previous output and have another output that would then be used by a third reader (eclipse.import?, p2?) that is able to parse the structure I showed before.

Can I execute an action before the resolution of the dependencies for a feature is performed?
In my scenario, I'd like to unpack the jar file containing the folders above when a referring feature needs it, but before the actual resolution is performed. Maybe this way the resolution will find it when it searches for it (via a rmap local entry pointing to the location where this action will output the result).
I tried using generators, but it just doesn't work. There is no error in the logs, but I get the dreaded "A selected specification is unresolved".
