Execution failed for task ':thirdPartyAudit'

[jvemugunta]

I am extending shield-custom-realm-example for support of Single Sing on (SS0) Siteminder product for JSON WEB TOKEN(JWT) authentication and authorization . I am stuck when adding a third party jar file compile 'io.jsonwebtoken:jjwt:0.9.0'

I am running with this error
Execution failed for task ':thirdPartyAudit'.
CLASSES ARE MISSING! [android/util/Base64.class, com/fasterxml/jackson/databind/ObjectMapper.class]

Can someone please advise on how to add third-party libraries to this project?
