This plugin copies the application, its dependencies and a startup script to a remote host.

The directory structure is similar to Capistrano:

  • ${rootDirectory}
    • current – link to the latest release directory
    • releases
        • lib – dependency JARs
        • ${name}_${scalaVersion}-${version}.jar – main application JAR
        • ${name} – startup script

The startup script starts the application in the foreground.


Add to your project/plugins.sbt:

addSbtPlugin("fi.onesto.sbt" % "sbt-mobilizer" % "0.2.0")


Enable the plugin according the SBT documentation.

An example:

lazy val myProject = (project in file("."))

Then add this to your build.sbt:

// If there's some kind of revision information available, you can store it into
// the application's root directory as a REVISION file.
deployRevision := Option("1234")
// You can use, for example to get a revision identifier:
//deployRevision := decoratedBuildNumber.value 

// Define deployment environments.
import fi.onesto.sbt.mobilizer.DeploymentEnvironment

deployEnvironments := Map(
  'staging    -> DeploymentEnvironment(
    hosts         = Seq(""),
    rootDirectory = "/opt/myapp"),
  'production -> DeploymentEnvironment(
    hosts         = Seq(""),
    rootDirectory = "/opt/myapp"))

See DeploymentEnvironment.scala for a list of all settings and defaults.

Deploy your code

To deploy your code use following syntax:

sbt "deploy <environment name>"

For example:
