Gradle project template for creating a Vert.x module

Project Shiny

Goal: create a working Vert.x projec using compiled Groovy verticles, Logback-based logging, and working unit and integration tests.

Starting with the original template, these are (roughly) the steps that I took to get the project in this state :

1. Clone
2. Remove unwanted files
3. Rename package directories (this is more easily done outside of IDEA, alas)
4. Add a groovy source directory and a groovy source file.
5. Modify mod.json
6. Run gradle idea to generate IDEA files - note that you must do this after you add groovy stuff.

##Open questions

1. Java source attaches nicely in IDEA - why isn't groovy source attaching?
2. How do you spin up multiple verticles? Looks like we still need an app starter verticle, which is consistent with Vertx 1.3.1. Not demonstrated yet.
3. Where do logs go? This is determined by log config, which is in src/main/resources/Logback.groovy. However I haven't really got this to work with any confidence.

##Closed questions

1. How do you run a compiled groovy verticle? Add groovy: to the mod.json
2. Where is mod.json documented? https://github.com/vert-x/vert.x/blob/docs_2.0.0/core_manual_groovy.md
3. Where is the vertx version set? gradle.properties#vertxVersion. Valid strings can be inferred from https://github.com/vert-x/vert.x/tags, and what you get with those tags in the google group. It's pretty informal at this point.
4. How do I add other dependencies to the build? Add a line to build.gradle like compile group: 'ch.qos.logback', name: 'logback-classic', version: '1.0.13'. Values can be inferred from maven repository values such as this mvnrepository.com entry for logback
5. How can I run an class that has a main() in it with gradle? I don't really want to do this; instead of a testing main, use a unit test. I would like to know for general interest though.
6. Why does RecordParser seem to want to throw an exception? Compiled groovy verticles need to have special strings in mod.json. Without that special string, all hell breaks loose.

###Apology

Some of these questions are not vertx dependant - in fact many of them are gradle dependant, a build system with which I have a few hours of experience.
