Stephen, I think that mentioning pom.xml is probably confusing Wyclif, because maven is a build-time tool.
Basically what you're saying is that you want to script the deployment process by just giving the versions of openmrs-core and all add-ons (both modules and OWAs). That would be great!
I imagine it should go in the openmrs-distro.properties file you give to the SDK. We'd need to extend this to support
owa.xyz. @raff, how would you approach this?
