...t-rules-style/src/main/kotlin/io/gitlab/arturbosch/detekt/rules/style/UnusedPrivateMember.kt

-                        bindingContext[BindingContext.DECLARATION_TO_DESCRIPTOR, it] !in referenceDescriptors
+                    val referenceDescriptors = (references + referencesViaOperator)
+                        .mapNotNull { it.getResolvedCall(bindingContext)?.resultingDescriptor }
+                        .map { it.original }


The resulting descriptors are not the same reference-wise. So I had to unwrap them in Kotlin 1.4.

It's the Kotlin version gradle-api ships with.

arturbosch · 2020-08-19T20:09:51Z

I would say lets merge this with the warning so our users have a working detekt version for Kotlin 1.4 if they do not use formatting to much.
Edit: code coverage should just be buggy here.

realdadfish · 2020-08-20T09:05:22Z

Kotlin 1.4 is smoke-tested currently in gradle/gradle#12660 and - with some luck - available with Gradle 6.7 - if Gradle does not decide to skip this upgrade until Gradle 7.

👍 LGTM

Nit: Out of interest - we can have trailing commas now, but why should we have them here?

Seems like IntelliJ autoformatted them for me here :/. Wasn't aware of.

Interesting! It works with 5.3 and running it with 5.0 revealed an error message saying it supports Gradle 5.3+.
