Sass asset handling for Play Framework 2.0

branch: master


Sass asset handling plugin for Play 2.x. Implemented as sbt plugin.


Sass compiler needs to be installed for plugin to work. This means that sass executable needs to be found in path. Sass can be installed by by installing sass gem.

gem install sass

You can verify that sass has been installed by following command:

% sass -v
Sass 3.1.16 (Brainy Betty)


Add following to your projects project/plugins.sbt

resolvers += "Sonatype OSS Releases" at ""

addSbtPlugin("net.litola" % "play-sass" % "0.3.0")

In addition you'll need to add settings to your project. On Play 2.2 this is done by modifying build.sbt and adding import for the SassPlugin, and adding SassPlugin settings.

import net.litola.SassPlugin

play.Project.playScalaSettings ++ SassPlugin.sassSettings

On Play 2.1 and Play 2.0 you should do following changes to project/Build.scala.

import net.litola.SassPlugin

val main = PlayProject(appName, appVersion, appDependencies, mainLang = SCALA).settings( SassPlugin.sassSettings:_* )

This adds Sass asset compiler to Play project. *.sass and *.scss files in app/assets directories will then be automatically compiled to *.css files. Files starting with _-character will be left out from compilation as per Play convention.


If you would like to pass your own command line arguments to Sass call, you can do it by overriding Sassplugin.sassOptions. For example to use Compass you can use following:

play.Project.playScalaSettings ++ SassPlugin.sassSettings ++ Seq(SassPlugin.sassOptions := Seq("--compass", "-r", "compass"))


The newest version only support Play 2.2. If you need support for older versions, please use 0.2.x or 0.1.x series.
