I have problem with updating Kotlin version in existing project.
Current Gradle:
com.android.tools.build:gradle:7.0.1
Current Kotlin:
org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.30
When I'm changing Kotlin version to
org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.20
I'm getting error:
> Unable to find method ''java.io.File
> org.jetbrains.kotlin.gradle.tasks.KotlinCompile.getDestinationDir()''
> 'java.io.File
> org.jetbrains.kotlin.gradle.tasks.KotlinCompile.getDestinationDir()'

I was trying to:
Update 1.
Updated all dependencies but still can't change Kotlin version.
How I can solve this problem ?
OK. I will write what helped me and it maybe would be helpful for someone in the future.
In this case there was problem with kotlin compatibility version in gradle libraries.
Run build with --stacktrace
./gradlew assembleDebug --stacktrace
and there was error not visible without --stacktrace.

After updating this library I was able to bump kotlin version.
