[forge-dev] JBoss Stacks: Requirements

The main idea behind the supportVersions (probably a bad name) was
availableVersions: 7.0.0.Final, 7.0.1.Final, 7.0.2.Final, 7.1.0.Final,
supportedVersions: 7.1.0.Final, 7.1.1.Final
Just meaning all available version should work, but everything is only
guaranteed to work with the supportedVersions. Maybe a Beta or CR could
be in available, but not fully supported as well. Just a thought that
really isn't a big deal.
What I think would be ideal if it's possible would be to have a
properties section with name value pairs. Then things like the
-logmodule or -someOtherArgument could be used for anything.
I would think the AS downloads would always be a zip as well. If other
consumers have no use for a packaging type it can be left off. Really if
we can have a properties section it could be used in there if needed.

>> So far the only information I would need is the version number, the current version (both seem to be taken care of so far) and whether or not the version of AS requires the -logmodule argument for JBoss Modules. Really since that's kind of a special use case it could just be hard-coded into the plugin code, but having some kind of metadata for something like that would be ideal IMO.

>>> The runtimes should include what type they are (e.g. JBoss AS, EAP) to allow categorisation, filtering, sorting
>>> The Yaml parser in use should be pluggable, to avoid introducing uncessary extra dependencies
>>> There should be a recommended runtime per major version and per minor version (so you can say "I want JBoss AS 7" and you get back AS 7.1.1.Final or you can say "I want JBoss AS 7.0" and you get back 7.0.2.Final).
>>> We're going to need to be careful about compat, eventually, so we need to get everything in there, and get it right. We'll have a long beta cycle ;-)
>>> There will be a client utility, written in Java. This should be a single source file, which projects can copy in. It must have no dependencies other than a Yaml parser.
>>> I think Rafael is going to take the lead on this. But we'll decide on Monday next week.

>> For example in the Forge plugin there is an option to execute CLI commands. That CLI API wasn't available until 7.1.1 IIRC. It *should* work for 7.0.x, but some operations that are available 7.1.1 might not be available in 7.0.x.
