Set up Kotlin source directory from Gradle Kotlin DSL

When converting Android Gradle files from Groovy to Kotlin, one thing that may not be clear is how to keep Kotlin sources within src/main/kotlin. We simply need to get the source sets by name and call java.srcDirs() as a function call. Works like a dream!

sourceSets {
    getByName("main").java.srcDirs("src/main/kotlin")
    getByName("test").java.srcDirs("src/test/kotlin")
    getByName("androidTest").java.srcDirs("src/androidTest/kotlin")
}
