Unresolved Reference Kotlinx in IntellijIdea. Even after adding the library

Question

I just wanted to taste Kotlin coroutines. Unfortunately, I haven't been able to use the library kotlinx in IntelliJ. I have downloaded the library through Maven.

1. Tried invalidating caches.
2. Rebuilt project.
3. Tried using it in a fresh project.
4. Even IntelliJ is suggesting kotlinx in auto-completion.
5. Still it says unresolved reference

I have tried most of the solutions on the web. But nothing worked.

Here are the steps that I am exactly doing.

Made a new project.

kotlinx is underlined since the library has not been added.

In project structure > modules > dependencies > add > library > maven Searched for the kotlinx library.

Downloaded the library.

Applied the settings.

kotlinx library is now visible in the External Libraries section.

Even the auto-completion is now suggesting kotlinx.

Still, nothing changes. The result is the same.

Answer 1

I have found the answer in the Kotlin slack channel. And to solve this particular issue add org.jetbrains.kotlinx:kotlinx-coroutines-core-jvm:1.5.0 instead of org.jetbrains.kotlinx:kotlinx-coroutines-core:1.5.0.

However, it is generally a good idea to learn a build system like Gradleor Maven and using those in the project. It makes life a lot easier.
