IntelliJ Idea: Unresolved reference: serializer

See original GitHub issue

Idea doesn’t compile project files with an error: “Kotlin: Unresolved reference: serializer”. I tried various cleanup task and IDE restarting and a project reimport but it doesn’t solve the issue.

Meantime gradle itself works perfectly without any errors.

build.gradle.kts

buildscript {
  repositories { jcenter() }

  dependencies {
    classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.0")
    classpath("org.jetbrains.kotlin:kotlin-serialization:1.3.0")
  }
}

apply {
  plugin("kotlin")
  plugin("kotlinx-serialization")
  ...
}

dependencies {
  compile(kotlin("stdlib", "1.3.0"))
  compile("org.jetbrains.kotlinx:kotlinx-serialization-runtime:0.9.0")
  ...
}

This problem is back:

serializer() function shows unresolved…

I see this intermittently day after day, not all the time, really weird. Gradle build is all ok. Looks like it’s the IDE.

To me it doesn’t fix it by restarting, I also have to delete the gradle.xml from .idea dir to fix it. Really annoying because restarting means quite a lot of reload, reindex, reimport etc… This should be reopened IMO.
