Configuration

We will use the following components to define Play Framework Scala-based SBT projects:

• Routes to define Play routings
• application.conf to define Play application configuration
• plugins.sbt to define SBT plugins, such as the Play Framework plugin
• The sample plugins.sbt file:

      addSbtPlugin ("com.typesafe.play" % "sbt-plugin" % "2.6.3")

• The logging configuration in the logback.xml file
• build.sbt configuration to define any Play modules, such as the Play WS module and Google Guice module, project name, Scala version and so on, as shown as follows:

Sample build.sbt file:

      name := "play-scala-fileupload-app"
      version := "1.0.0" 
      lazy val root = (project in file(".")).enablePlugins(PlayScala) 
      scalaVersion := "2.12.2" 
      libraryDependencies += guice 
      libraryDependencies...
