Bucket name should not contain '/'

[pavanag2017]

My Requirement is bucket contains 'parentBucket/folder1/folder2/folder3/abc.txt'.

While running mock, I get below error:

java.lang.IllegalArgumentException: Bucket name should not contain '/'

at com.amazonaws.services.s3.internal.BucketNameUtils.exception(BucketNameUtils.java:189)

Can you please fix it asap.
