Using Ant as a continuous testing tool

So after much hunting I failed to find a continuous testing tool for IntelliJ 14.

I stumbled across a post that references uses eclipse and Ant in order to simulate this. On save, Ant then runs the tests for any tests that were modified.

I've tried to replicate this but, alas! I've never used Ant before and am finding it extremely difficult. I've setup and configured a generic Ant build file in Intellij but simply cannot figure out how to achieve my task.

Any help, pointers in the right direction is very much appreciated. I've searched but only found information that needs to be decrypted first.
