Set up the project and S3 bucket

In this recipe, we are reusing the Lambda we created in the Your Lambda with AWS CLI recipe. Generate a JAR by running mvn clean package inside that project, and upload the JAR to S3:

aws s3 cp target/original-serverless-cookbook-lambda-handler-with-pojos-0.0.1-SNAPSHOT.jar s3://serverless-cookbook/lambda-handler-with-pojos-0.0.1-SNAPSHOT.jar --profile admin

Replace the bucket name serverless-cookbook with your bucket's name. Refer to the Getting ready section of the recipe Your First AWS CLI to create the S3 bucket.
