kotlinlang

I'm using ktor, but think this might be a Gradle/IntelliJ question.
I have
```kotlin("plugin.serialization") version "1.5.20"```
declared in my `build.gradle.kts` file, and yet I cannot use the `*import* kotlinx.serialization.Serializable` in my code. The "External Libraries" part of the project explorer does not show `Gradle:io.ktor:ktor-serialization:1.6.1` like the example code in <https://ktor.io/docs/creating-http-apis.html> does when I run that.

I'm not sure what I need to do in order to get IntelliJ/Gradle to install the necessary dependencies so I can use them in the code?

Bah, ignore me. My versions were wrong in the `build.gradle.kts` for the dependencies. I was matching the kotlin, not the ktor, versions.

You shouldn't be matching the ktor versions either, you need to include the runtime dependency for kotlinx serialization (see <https://github.com/Kotlin/kotlinx.serialization#dependency-on-the-json-library>).  There's two parts to kotlinx serialization: the compiler/gradle plugin, which matches the Kotlin version (and is what you put in the plugins block), and the runtime library, which has it's own version and is a normal maven dependency
