Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.15

Error

Solution

Changing this in the file build.gradle solved my problem.

From

ext.kotlin_version = '1.3.50'

to

ext.kotlin_version = '1.6.0'

I had this problem in a Flutter project.

In my case, a line for kotlin-gradle-plugin was missing in the Android build.gradle file, so adding ext.kotlin_version = ‘1.6.10’ didn’t fix it.

After adding

classpath “org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version”

the error was gone.
