Adding an integration test source set

[bmuschko]

I was trying to add another test source set to be included in code coverage. After having a brief look at the plugin code, it looked as if you can added through the extension method addCoverage:

task integrationTest(type: Test) {
    ...
}

cobertura {
    addCoverage(integrationTest, sourceSets.main)
}

However, when executing the task, I run into an error:

:integrationTestCoberturaReport FAILED

FAILURE: Build failed with an exception.

* What went wrong:
A problem was found with the configuration of task ':integrationTestCoberturaReport'.
> File '/Users/ben/testproject/build/cobertura/main/cobertura-test.ser' specified for property 'serFile' does not exist.

Is there a way of doing this? Maybe it's just not documented. Sorry, I didn't have a deep look at the task code yet.
