IntelliJ IDEA Scala inspection : import play.api.xxx conflict with com.company.play package

I want to make a helper class at the root of my core project using play-json from typesafe, something like

package com.company

import play.api.libs.json.JsValue

object Helper {

  implicit class RichJson(json: JsValue) {
    def doStuff() //...
  }
}

The problem is that I have somewhere else in the project a package com.company.play

package com.company.play

class Foo() { //... 
}

In IntelliJ IDEA 2018.2.4 CE, the line import play.api.libs.json.JsValue is in error with telling me "cannot resolve symbol api" and when Ctrl+Click on the play it goes to the folder containing my Foo.scala file

If I compile the solution with sbt outside of IDEA, there is no problem.

If I put the Helper object in a subpackage (eg com.company.common) there is no error (which also means the dependency is correct in my build.sbt)

I don't understand why IDEA miss this, com.company.play isn't even in the dependencies of the core project. I already tried to invalidate cache, and it doesn't help.

The problem is that Intellij gives precedence to the package play into your project, instead of the package coming from the framework, when resolving the import of JsValue inside com.company scope.

If you really want to keep that name for com.company.play, there is a simple workaround using a fully-qualified import, just prefix like this:

import _root_.play.api.libs.json.JsValue
