Adding dependencies to a Scala project (sbt)

Here's a link to the Typesafe repository, which is the official repository maintained by Typesafe:

Type jerkson in the search box, which will show you all the related projects hosted on the repository.

You should be able to see the path, such as:

com/codahale/jerkson_2.8.2/0.5.0

You can decompose it to 3 components.

Try this:

libraryDependencies += "com.codahale" % "jerkson_2.8.2" % "0.5.0"

If you want the latest integration, you may use latest.integration as the third parameter

libraryDependencies += "com.codahale" % "jerkson_2.8.2" % "latest.integration"

In general, I would try Maven repository first.

Here's what Maven repository looks like:

This is nice because you can see a tab for sbt, and you can simply copy that to your code. Unfortunately, I did not see the library you want in Maven.

Based on your comments to the other answers, I believe what you wish to do is specify the dependency directly to the github URL. This has been asked before. Both answers are correct and should prove useful for you.
