# serialization

I keep running into err: "Cannot access 'Serializable': it is internal in 'kotlin.io'. I've searched previous messages and double checked my dependencies:
• common = org.jetbrains.kotlinxkotlinx serialization runtime common${Versions.serialization}
• android = "org.jetbrains.kotlinxkotlinx serialization runtime${Versions.serialization}"
• ios = "org.jetbrains.kotlinxkotlinx serialization runtime native${Versions.serialization}"
plugin is applied
metadata is set in settings.gradle

I see a similar error in the debugger: Cannot access '<http://java.io|java.io>.Serializable' which is a supertype of 'kotlin.Char'. Check your module classpath for missing or conflicting dependencies

[edenman]

probably worth filing with more details (kotlin version, serialization version, IDE version, etc) if your issue is at compile time

Kotlin 1.3.72, serialization=0.20.0, IDE=Intellij 2020.2. It happens in IDE as well as from gradle command line

Not sure if it's related but I was seeing a similar issue because I didn't have the right `import`s.

Adding import kotlinx.serialization.* fixed it for me.
