Can not access s3-us-west-2.amazonaws.com

[hax0r]

hi, there:
I want to build the Nifi in my own computer. But I got an error:Could not 
transfer artifact net.minidev:json-smart:pom:2.3-SNAPSHOT from/to 
dynamodb-local-oregon 
(https://s3-us-west-2.amazonaws.com/dynamodb-local/release): Access denied to: 
https://s3-us-west-2.amazonaws.com/dynamodb-local/release/net/minidev/json-smart/2.3-SNAPSHOT/json-smart-2.3-SNAPSHOT.pom
 , ReasonPhrase:Forbidden.
Is there any other alternative repo? Thx in advance.
