§About SBT Settings

§About sbt settings

The sbt build script defines settings for your project. You can also define you own custom settings for your project, as described in the sbt documentation .

To set a basic setting, use the := operator:

val main = PlayProject(appName, appVersion, appDependencies).settings(
  confDirectory := "myConfFolder"     
)

§Default settings for Java applications

Play 2.0 defines a default set of settings suitable for Java-based applications. To enable them add the defaultJavaSettings set of settings to your application definition:

val main = PlayProject(appName, appVersion, appDependencies, mainLang = JAVA)

These default settings mostly define the default imports for generated templates. For example, it imports java.lang.*, so types like Long are the Java ones by default instead of the Scala ones. It also imports java.util.* so the default collection library will be the Java one.

§Default settings for Scala applications

Play 2.0 defines a default set of settings suitable for Scala-based applications. To enable them add the defaultScalaSettings set of settings to your application definition:

val main = PlayProject(appName, appVersion, appDependencies, mainLang = SCALA)

These default settings define the default imports for generated templates (such as internationalized messages, and core APIs).

§Play project settings with their default value

When you define your sbt project using PlayProject instead of Project, you will get a default set of settings. Here is the default configuration:
