How to get the current source directory in gradle?

I have different flavors in a gradle build file:

I would like to put a .properties file in each app/src/flavor/ directory

 app
   src
      flavor1/
         java/
         app.properties
      flavor2/
         java/
         app.properties

and then use the references to that file in a task.

How do I reference the current flavor's directory in groovy/gradle?

If you really want per-flavor properties, here's an off-the-cuff approach.

Step #1: Come up with your list of flavors. For the purposes of this answer, I'll use vanilla and chocolate.

Step #2: Create, in your module root, a properties file per flavor (i.e., vanilla.properties, chocolate.properties).

Step #3: In your productFlavors closure, you would have the code to load up that flavor's properties and use them, using something like this:

productFlavors {
    vanilla {
        applicationId "com.commonsware.android.gradle.hello.vanilla"

        def propFile = rootProject.file('vanilla.properties')

        if (propFile.canRead()) {
            def Properties flavorProps = new Properties()

            flavorProps.load(new FileInputStream(propFile))

            // you can now access flavorProps[...] for various string keys
            // identified here as ..., like flavorProps['foo']
        }
    }

    // repeat for chocolate and other flavors
}

The only wrinkle in the above code that I can think of off the top of my head is my use of rootProject. My sample code for all of these Gradle tricks are for a project without modules, but Android Studio projects often will be set up with your code in an app/ module (a.k.a., subproject). I have not experimented with this code yet in that scenario, and I do not know if rootProject will refer to the module or the top-level project directory. There may be a different value to use, other than rootProject, to get to the module.
