* Outside of Gradle build scripts, you must explicitly call a getter for the `DependencyCollector` and `add`.
** `dependencies.add("implementation", x)` becomes `getImplementation().add(x)`
* You cannot declare dependencies with the `Map` notation from Kotlin and Java.
Use multi-argument methods instead in Kotlin and Java.
