sbt-s3 is a simple sbt plugin that can manipulate objects on Amazon S3.

• add to your project/plugin.sbt the line: addSbtPlugin("io.github.morgaroth" % "sbt-s3" % "0.10")
• then add to your build.sbt the line: enablePlugins(S3Plugin)

You will then be able to use the tasks s3-upload, s3-download and s3-delete commands All these operations will use HTTPS as a transport protocol.

Here is a complete example:

project/plugin.sbt:

addSbtPlugin("io.github.morgaroth" % "sbt-s3" % "0.10")

build.sbt:

mappings in upload := Seq((new java.io.File("a"),"zipa.txt"),(new java.io.File("b"),"pongo/zipb.jar"))

host in upload := "s3sbt-test.s3.amazonaws.com"

credentials += Credentials(Path.userHome / ".s3credentials")

~/.s3credentials:

realm=Amazon S3
host=s3sbt-test.s3.amazonaws.com
user=<Access Key ID>
password=<Secret Access Key>

Just create two sample files called "a" and "b" in the same directory that contains build.sbt, then try:

$ sbt s3-upload

You can also see progress while uploading:

$ sbt
> set S3.progress in S3.upload := true
> s3-upload
[==================================================]   100%   zipa.txt
[=====================================>            ]    74%   zipb.jar
