Replacement of new JacksonFactory to get google credential in Java
Finally found the JacksonFactory class. It has been separated and is available in the following dependency:
<dependency> <groupId>com.google.http-client</groupId> <artifactId>google-http-client-jackson2</artifactId> <version>1.15.0-rc</version> </dependency>
So the Java code doesn't change.
Or you can too download the featured.zip version of the library:
