Im pretty sure the reason for this is because of mismatched versions so im sharing all my pom files, i have modules of project when i was working in one of the module where i had to use cognito i added dependency and changed all other to newer version as cognito does not support older version but now in another module im getting this error

You should add aws core dependency rather than full sdk as suggested in above answer

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-core</artifactId>
    <version>1.11.822</version>
</dependency>

use version 1.11.873 (aws-java-sdk-core)
it helped for me too! but still its not clear why in detail...
@hasan Its because aws has created common features or common stuff inside this core dependency for example convert object to json or vice versa. If you are using any dependency for example s3 and if it doesn't include core dependency you have to add that as separate dependence.

Adding aws-java-sdk dependency will work.
