[wildfly-dev] Where to add module definition in wildfly/build

[Cheng Fang]

When I add a new module definition for a new sub-module into 
wildfly/build directory, what is the right place? 
wildfly/build/src/main/resources/modules/system/layers/base/org/wildfly/extension?

I see various modules using 3 different places:

wildfly/build/src/main/resources/modules/system/layers/base/org/wildfly/extension

wildfly/build/src/main/resources/modules/system/layers/base/org/wildfly

wildfly/build/src/main/resources/modules/system/layers/base/org/jboss/as

The hacking page (https://community.jboss.org/wiki/HackingOnWildFly) 
says to use the jboss/as one, but I suspect it could be out of date.

Thanks,
Cheng
