Incompatibility of idea plugin and scala plugin in Gradle

The company considers starting to work in Scala.  However, we could not include both plugins - scala and idea in same Gradle project.  For example, starting a fresh & empty project we call 'sc' with this build.gradle:

plugins {
    id 'idea'
    id 'scala'
}

version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

we get: Task with name 'ideaProject' not found in root project 'sc'.

Does anyone know how to resolve this show stopper issue?

Versions:

Intellij: 2019.1, Gradle: 4.10.2

Thanks!
