I am trying to fetch some data from Google Analytics using Google Analytics reporting v4 API. I am using maven so included all the 9 modules in maven dependency.
However while running the sample java code from https://developers.google.com/analytics/devguides/reporting/core/v4/quickstart/service-java
I am getting NoClassDefFoundError. On debugging further the actual line which was failing is Utils.getDefaultJsonFactory();
Exception in thread "main" java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/json/async/NonBlockingJsonParser
