Why are managed css/less assets not processed by sbt-less plugin in Play 2.3?

Question

I upgraded to play 2.3, and followed the instructions described in Using LESS CSS to use the less plugin. However, the less file is not being compiled to css and sent to target. The JS files however are working.

All I did was to add the less and jslint plugins as follows:

addSbtPlugin("com.typesafe.sbt" % "sbt-less" % "1.0.0")

File structure:

/assets
  /javascripts -> *.js files are linted and staged
  /stylesheets -> *.less files not working

Answer 1

Thanks! It fixed now.

• Only when *.scala full build file is used. Add the following imports to the build:

  import com.typesafe.sbt.web.SbtWeb.autoImport._
  import com.typesafe.sbt.less.Import.LessKeys
  

• Add the following to project settings:

  includeFilter in (Assets, LessKeys.less) := "*.less"
  
  // for minified *.min.css files
  LessKeys.compress := true
