 If you don't control the projects that will consume the Grease AAR, you should only bundle in
 dependencies that you own, to be sure that they won't be present in the classpath of the consumer.

+### Transitivity
+
+When you add a grease dependency, by default all transitive dependencies are greased as well, so
+they will become part of the fat AARs. To avoid this, you can mark the configuration as non transitive:
+
+```kotlin
+configurations["grease"].isTransitive = false
+configurations["greaseRelease"].isTransitive = false
+configurations["greaseDebug"].isTransitive = false
+
+// Variant specific configurations are created lazily so you must wait for them to be
+// available before modifying them.
+configurations.configureEach {
+    if (name == "greaseBlueCircleDebug") {
+        isTransitive = false
+    }
+}
+```
