SBT + Idea 13 => Cannot resolve symbol

Question

I\'m using SBT + Idea 13.1.1 and I have all my SBT file in red:

name := \"Transformer\"

version := \"1.0\"

libraryDependencies ++= Seq(
  \"com.github.scop         


        

Answer 1

Restarting IntelliJ fixed it for me.

Answer 2

In case none of the other solutions work and you are in the same boat as me, where you see a Cannot resolve symbol ... in the build.sbt and all files that have sbt dependencies, and where there are no sbt dependencies in External Libraries, running File | New | Module from Existing Sources... and selecting the build.sbt may fix it for you as it fixed it for me.

Answer 3

I had a similar problem when I updated to SBT 0.13.7. IntelliJ started marking operators such as := and ++ in red with message "Cannot resolve symbol"

My steps to fix this solution were as follows:

1. In IntelliJ under Files | Settings, I switched my SBT Runner to use a Custom Launcher (and gave my path to sbt-launch.jar which for me was /opt/sbt/bin/sbt-launch.jar).

2. After testing that I can still compile after #1 above, I then had to invalidate the cache and restart; under Files | Invalidate Caches / Restart...

That's it! :-)

Answer 4

I had a similar problem on 14.1.2; in my case adding

libraryDependencies += "org.scalatest" % "scalatest_2.11" % "2.2.1" % "test"

and then trying to

import org.scalatest._

Would resulted in: cannot resolve symbol scalatest

Downgrading sbt (0.13.8 -> 0.13.7); in build.properties solved the problem.

here are more details.

Answer 5

Had the same problem in IDEA 14.0. Nothing above worked.

Upgrade to IDEA 14.1.1 did the trick.

Answer 6

Updating my build.properties from 0.13.8 to a newer version, like 0.13.15, solved it for me. Reference github issue.
