AmazonClientException

I've got some troubles with running this sample.
I've followed instructions on http://aws.amazon.com/ru/developers/getting-started/java/, and after running mvn clean compile exec:java I've got AmazonClientException(Unable to execute HTTP request: peer not authenticated) followed by "Unable to execute HTTP request: peer not authenticated". This things happen when I am trying to create bucket, so I've got "Creating bucket my-first-s3-bucket-865cc23b-7f73-4e09-a9d9-c38382d72e2b" and then an error.
I've looked throw https://forums.aws.amazon.com/message.jspa?messageID=429971, but unfortunately I don't completely understand how to use suggested solution (http://javaskeleton.blogspot.ie/2010/07/avoiding-peer-not-authenticated-with.html) here.
