Jar deployment broken on serverless 1.27.2

lambda

#1

Provider : AWS
FUnction : Lambda
Java8

I have integrated serverless with Jenkins and trying out CD pipeline.
i trigger a maven build and once the jars are generated.
i call the serverless deploy.

The S3 bucket has the Zip file with jar (only jar nothing else).
The deployment is sucessfull.
But execution of lambda throws “class not found”

If i downlad the S3 Zip file and upload the contained jar manually in AWS console it executes fine.
can you please help me, i am blocked on this.
