I have added the scalapb plugin

// Scala Protocol Buffers Compiler
addSbtPlugin("com.thesamet" % "sbt-protoc" % "0.99.8")

libraryDependencies += "com.trueaccord.scalapb" %% "compilerplugin" % "0.6.0-pre5"

build.sbt modifications

PB.targets in Compile := Seq(
  scalapb.gen() -> (sourceManaged in Compile).value
)

If I run

sbt protoc-generate

or

sbt compile

from my project root, the protobuf scala source gets generated fine, is found by intellij, and all is good. Great.

However, whenever I build my project in intellij, the scala source files do not get generated.

Scala version : 2.11.8

Intellij scala plugin version 2016.3.9

I imported the project into IntelliJ and created a new SBT project btw.

This is an IntelliJ issue that impacts any SBT project that uses source generators (not just ScalaPB).

Based on this comment https://youtrack.jetbrains.com/issue/SCL-9301#comment=27-2041907 there is a solution for IntelliJ 2017.1

Thanks for the quick reply Nadav, I'll try out 2017.1 ASAP.
