Full Configuration Example

Documentation has moved

The documentation for sbt has moved to http://scala-sbt.org. The new location for this page is http://scala-sbt.org/release/docs/Examples/Full-Configuration-Example.

Full Configuration Example

Full configurations are written in Scala, so this example would be placed as project/Build.scala, not build.sbt. The build can be split into multiple files.

External Builds

• Mojolly Backchat Build
• Scalaz Build
  • Source Code Generation
  • Generates Scaladoc and Scala X-Ray HTML Sources, with a unified view of source from all sub-projects
  • Builds an archive will the artifacts from all modules
  • "Roll your own" approach to appending the Scala version to the module id of dependencies to allow using snapshot releases of Scala.
