Jackson marshalling unmarshalling requires following jar files of same version    jackson-core jackson-databind jackson-annotations  Make sure that you have added all these with same version in your classpath  In your case jackson-annotations is missing in classpath

Use jackson-bom which will have all the three jackson versions i e jackson-annotations  jackson-core and jackson-databind  This will resolve the dependencies related to those versions

Use Jackson-annotations jar will solve the problem  as it worked for me

I had the same error message  In my case  Jackson consisted of multiple JAR files  Sadly  they had different versions of jackson-core and jackson-annotations which resulted in the above exception   Maybe you don t have the jackson-annotation JAR in your classpath  at least not in the correct version  You can analyze the used library versions with the command mvn dependency tree

Even though this answer was too late  I m adding it because I also went through a horrible time finding answer for the same matter  Only different was  I was struggling with AWS Comprehend Medical API   At the moment I m writing this answer  if anyone come across the same issue with any AWS SDKs please downgrade jackson-annotaions or any jackson dependencies to 2 8   versions   The latest 2 9   versions does not working properly with AWS SDK for some reason  Anyone have any idea about the reason behind that feel free to comment below   Just in case if anyone is lazy to google maven repos  I have linked down necessary repos Check them out    Jackson-Core Repo Jackson-Core-Databind - 2 8 11 3 Jackson-Core - 2 8 6 Jackson Annotations - 2 8 11
