Detekt 1.20.0 fails on older Kotlin versions

[guycall]

Expected Behavior

I have a Spring Boot app, jvmTarget 11, Kotlin 1.5.32 and with Detekt 1.19.0. Running ./gradlew --debug detekt works without problem. After upgrading to 1.20.0 I would expect it to continue to run.

Observed Behavior

With version 1.20.0 I get the error:

...
[ERROR] [org.gradle.internal.buildevents.BuildExceptionReporter] FAILURE: Build failed with an exception.
[ERROR] [org.gradle.internal.buildevents.BuildExceptionReporter]
[ERROR] [org.gradle.internal.buildevents.BuildExceptionReporter] * What went wrong:
[ERROR] [org.gradle.internal.buildevents.BuildExceptionReporter] Execution failed for task ':detekt'.
[ERROR] [org.gradle.internal.buildevents.BuildExceptionReporter] > Invalid value passed to --jvm-target

I tried with various versions of Kotlin and only 1.6.20 and 1.6.21 worked:

1.5.31 -> Failed
1.5.32 -> Failed
1.6.0 -> Failed
1.6.10 -> Failed
1.6.20 -> OK
1.6.21 -> OK

Your Environment

• Version of detekt used: 1.20.0
• Version of Gradle used: 7.2
• Operating System and version: Windows 10
• Version of Kotlin used: 1.5.32

After upgrading to 1.20.0 I would expect it to continue to run.

That's not the case.

We publish the list of versions we build against on this page:
https://detekt.dev/docs/introduction/compatibility

If you're diverging from those versions, things might not work properly. If you're using the Gradle Plugin, that's even more likely due to how Gradle embeds a Kotlin version in its runtime.

Moreover, this issue has been already discussed here:

Closing as it's essentially a duplicate. Feel free to re-opne if you have more context to share.
