less-sbt

[Anton Kulaga]

When I added sbt-web to my project I immediately got 

"DeserializationException: Expected Int as JsNumber, but got null 

No source available, here is the exception stack trace: ->spray.json.DeserializationException: Expected Int as JsNumber, but got null"

 error. 

Probably something in configuration was missing. I wonder does sbt-less and sbt-web in play require some other config than adding them to plugins.sbt and telling  lazy val main = (project in file(".")).enablePlugins(PlayScala,SbtWeb) ?

I managed to find the root of the problem. When I create assets/stylesheets/main.less  and leave if empty I get this thisspray.json.DeserializationException I created an issue on that  https://github.com/playframework/playframework/issues/2991

Thanks, an empty file sounds like an edge case that isn't handled.

That issue should be fine, but there's also the sbt-less project if you want to add an issue there: https://github.com/sbt/sbt-less/issues

Cheers

Thank for the suggestion. I think sbt-less has a big room for improvements as it is very hard to deal with its errors ( https://github.com/sbt/sbt-less/issues/21 )
