Currently ModuleDetector[1] is capable of detecting module names from pom.xml files, build.xml files, and MANIFEST.MF files. But I would also like to look for Gradle module names.

Typically in a multi-module Gradle project, the module name would match the subdirectory that the module is in, but it can also be overridden by settings.gradle[2]. The easy way would be to find the build.gradle file the same way it looks for the other files, and take that file's parent directory name:

./
|-- settings.gradle
|-- build.gradle
    |-- moduleA/
        |-- build.gradle
        |-- build/   (contains for example **/checkstyle-result.xml)
    |-- moduleB/
        |-- build.gradle
        |-- build/

So as an example, when we find ./moduleA/build/reports/checkstyle/checkstyle-result.xml, that belongs to the ":moduleA" gradle module.
