IntelliJ Idea sbt managed source file
intellij-idea, sbt, sbt-buildinfo, scala
Solution
Grega, are you working in a Play Framework project? Or do you have any SBT sub-projects? I don't have a complete answer, but may have a lead.
This same problem shows up in my IDEA projects when using sbt-buildinfo and sbt-scalaxb. Frustratingly, it has worked intermittently—usually after lots of tinkering around, but inexplicably stops.
I wound up digging a bit deeper (and eventually issued bug report SCL-7182 to JetBrains), and noticed the root cause was having a sub-project. When present, IDEA doesn't correctly identify `src_managed` for the root project, but does for the sub-project.
A work-around, for now, is to manually add the correct `src_managed` directory to your project's sources using the Project Structure dialog.
For reference, I'm running version 0.38.437 of the Scala plugin on IntelliJ IDEA 13.1.3.
Problem
I am using sbt-buildinfo plugin that generates Scala source from my build definitions, allowing me to reference project name, version, etc. from my Scala code. It does this by generating a file BuiltInfo.scala with the following contents: ``` package hello case object BuildInfo { val name = "helloworld" val version = "0.1-SNAPSHOT" val scalaVersion = "2.10.3" val sbtVersion = "0.13.2" } ``` in target/scala-2.10/src_managed/main/sbt-buildinfo/BuildInfo.scala. Everything compiles and I can reference those vals. However, IntelliJ Idea doesn't recognize BuildInfo.scala as a managed source file, so that it would stop showing me errors. Any idea how to do that? Thanks!
