aws-s3-scala 
Scala client for Amazon S3
How to use
Add a following dependency into your build.sbt at first.
libraryDependencies += "jp.co.bizreach" %% "aws-s3-scala" % "0.0.15"Then you can access S3 as following:
import jp.co.bizreach.s3scala.S3
import awscala.s3._
import awscala.Region
implicit val region = Region.Tokyo
implicit val s3 = S3(accessKeyId = "xxx", secretAccessKey = "xxx")
val bucket: Bucket = s3.createBucket("unique-name-xxx")
bucket.put("sample.txt", new java.io.File("sample.txt"))s3-scala also provide mock implementation which works on the local file system.
implicit val s3 = S3.local(new java.io.File("s3data"))Major methods are implemented in this mock, however some methods are not implemented.
These methods throw NotImplementedError if invoked.
