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!
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.
