Sbt not resolving Scalatest on Intellij IDEA

I know there are already answered questions about this, but they didn't work for me, maybe because they are too old now.

So I'm creating a scala project on Intellij IDEA Ultimate (SDK 16.0.1). I compile it using sbt. I created a MainTest class in src/test/scala with the following content :

import org.scalatest.funsuite.AnyFunSuite

class MainTest extends AnyFunSuite {
  test("Example") {
    assert(1 == 1)
  }
}

On my build.sbt file I have :

name := "my-scala-project"

version := "0.1"

scalaVersion := "3.0.0-M2"

libraryDependencies += "org.scalatest" %% "scalatest" % "1.4.RC2" % Test

I have also installed the library org.scalatest:scalatest_2.11:3.1.0 from Maven from the File > Project Structure... > Project Settings > Libraries window

On the editor I can see that Intellij is unable to resolve the import on my test file as it is marked in red. When I run sbt clean test, I get this error message :

[error] -- [E006] Not Found Error: path\to\project\src\test\scala\MainTest.scala:4:2
[error] 4 |  test("Example") {
[error]   |  ^^^^
[error]   |  Not found: test
[error] one error found
[error] one error found
[error] (Test / compileIncremental) Compilation failed

Why isn't it working ? I thought I have done everything as expected. Ideally I would like to use the latest 3.2.9 version of Scalatest.

Thanks

Solution

  • I combine all the help I got in the comment :

    I had to write this in the build.sbt file :

    name := "meteo-france-client"

version := "0.1"

scalaVersion := "3.0.0-M2"

libraryDependencies += "org.scalatest" %% "scalatest" % "3.3.0-SNAP3" % Test

    Then sbt reload and sbt clean compile and it works. However I now get this exceptions :

    I'll make another post about it : Sbt unable to find List class definition on Scala 3.0.0-M2

    Thanks for all who have helped me here
