Add library dependencies to SBT, for SBT (not the project managed by SBT)

I am trying to create a Task for SBT, so when I type "deploy" the task creates a .jar and then deploys it via SCP (I need an SSH library). The problem I'm struggling with is that I don't know know to add a library dependency (an SSH library) for build.sbt itself. I have libraryDependencies += "org.apache.commons" % "commons-vfs2" % "2.2" but this makes the library available to the project code, not the the SBT script "build.sbt" where I have to define the task.

You have two options:

First, if you plan to re-implement the same functionality in multiple projects, the best thing to do would be to create your own sbt plugin - it is basically just another scala project, thus you add the dependency in the build.sbt of that project.

Second, if you only need it for one project, and don't want to publish a plugin for it. SBT is recursive that means you can modify the SBT used to manage your project. This way you need to add your dependency to ./project/build.sbt instead of ./build.sbt - also I would recommend you write your task in a Scala file inside project.

That sounds exactly like what's an sbt plugin ! Effectively a "sbt library".

For example, maybe https://github.com/shmishleniy/sbt-deploy-ssh would be of help to you ?

To use them, you'll need to edit the plugins.sbt file, not the build.sbt one

For example, for this ssh one, you'll need to add to your plugins.sbt file :

resolvers += "JAnalyse Repository" at "http://www.janalyse.fr/repository/"
addSbtPlugin("com.github.shmishleniy" % "sbt-deploy-ssh" % "0.1.4")
