Refer to the SBT Reference Manual for more advanced usage. This recipe focuses very narrowly on aspects of SBT relevant to Spark development and intentionally glosses over the more complex configurations andĬommands. You are most likely to benefit from adopting SBT if you're writing a pure Scala Spark application or you have a mixed

SBT manages library dependencies internally with Apache Ivy, but you do need to interact directly with Ivy to use this feature. It adopts many of the conventions used by Apache Maven.Īlthough it has faced some criticism for its arcane syntax and the fact that it's "yet another build tool", SBT has become the de facto build SBT is a Scala-based build tool that works with both Java and Scala source code.
