Building gatling with gradle

So, assuming I have finished writing the simulations, I need to use gradle + its wrapper so it would be easy for others to run their tests. However, I have 0 experience in building applications. I found this project:
http://www.rallydev.com/community/engineering/load-testing-gatling-and-gradle

But it didn’t helped me a lot. What should I start with and how long would it take for me?

We plan on having our own Gradle plugin but that won’t happen any time soon.

I’m aware of 2 community gradle plugins:
https://github.com/vincentkok/gradle-gatling

https://github.com/buhe/gradle-gatling-plugin

Hope it helps
