Exception in thread "main" :test FAILED

And adding:

jacoco {
    toolVersion = "0.7.0.201403182114"
}

Fixes the problem!

Just to let you know that I had the same problem, also noticed the brand new jacoco version, and submitted a pull request to update the default jacoco tool version: https://github.com/gradle/gradle/pull/255

This is fixed in 2.0 and beyond (for sure) not sure what actually happened in 1.12
