   Typo: `','` at the end of the first sentence. No `'.'` at the end of the 
second sentence.
   The same for the Directory property.

 Review comment:
   Could you please use the same scheme for property names: lower case with 
hyphens like in case of `file-name` and `storage-account-name`
   The same for `Directory-name` below.

 Review comment:
   12.0.1 has been released in the meantime. Please update to this non-beta 
version.
   Could you please also move this compile dependency in front of the test 
dependencies?
   I would put it before jackson-core beacuse the jackson version override is 
needed by this dependency.
