Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.

com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK AUTHORS
File1: C:\Program Files\Android\Android Studio\gradle\m2repository\com\android\tools\external\lombok\lombok-ast\0.2.3\lombok-ast-0.2.3.jar

Your app has a duplicate file in APK AUTHORS.
There are two copies of lombok-ast-0.2.3.jar in your project.
Find out why you have two and remove one.

Closing this, since it's unrelated to the library.
