Re: [jboss-as7-dev] Automatically generate AS7 module.xml files from maven poms?
It might be a reasonable thing to generate a descriptor from a pom as a
starting point. However, they are not really one-to-one, so the majority
case will require alterations. Various reasons include:
1. Maven doesn't really separate runtime deps from compile time deps
properly (only workable way is "provided", which is rarely used).
2. Our core modules (e.g. javax.*) are not represented in maven
3. Transitive deps in maven are usually wrong (only a "bom" approach
leads to "correct" deps)
4. While a slot could be an artifact version, that's not the best
approach (you want a slot to be a compatibility group, not a minor
version so that updates are easy)
5. Path filtering can't be represented.
Although, isn't your problem more of the AS dependencies being out of
sync with a pom's transitive dep? If so the same problem exists with the
maven BOM approach that we use. (AS redefines all deps using a BOM to
avoid broken/wrong deps)

I've been working on a maven plugin to create extra modules for

is pretty nice to work with. Once I've got my forked surefire plugin working, I can
take a look if the general consensus is that we should go with something like this
