For reference, there was an earlier discussion around this general problem:

For example, if I have class which imports some classes from jboss-common-core module (let's assume that's the name) and some other classes from jboss-transaction-integration module then the build completes successfully and it's only during runtime that I start running into CNFE and/or NCDFE issues. I then I have to individually track down these dependencies *one at a time* and then go back to add it as a dependency in my module.xml.

I am aware that just adding anything and everything in the module.xml isn't a right approach, but atleast for classes which are directly imported into other classes of a module, it would be better to somehow automate (or better manage) the process of setting up the module.xml. That would atleast minimize the time spent in fixing the module.xml by trial and error method. Thoughts?
