+The Jackson libraries dependencies ships with duplicate license files, which can be ignore by adding to the `buildTypes` part of your Gradle file a `packagingOptions` element to include the license files:
+```groovy
+    buildTypes {

+        packagingOptions {
+            exclude 'META-INF/ASL2.0'

+        }
+    }
+```
