Error when running tests with coverage

[antonKozyriatskyi]

When running unit tests with coverage in Android Studio I'm getting the following error dialog:

After clicking OK the following error message appears in Build Output tab (though coverage also appears as expected):

Kotlin: 1.5.10/1.5.21 Poko: 0.8.1 AGP: 4.2.1/4.2.2 Android Studio: Android Studio 4.2.2 - Build #AI-202.7660.26.42.7486908, built on June 24, 2021

This is from the IDE's built-in coverage tool, right? As opposed to a Jacoco Gradle plugin or something?

What version of the IDE and AGP are you using?

Does the same thing happen with Kotlin 1.5.0 and 1.5.21?

I'm on vacation right now so it's gonna take me awhile to look at this closely.

Correct. The issue appears only when using built-in coverage tool even if Coverage runner is set to Jacoco.

What version of the IDE and AGP are you using? Does the same thing happen with Kotlin 1.5.0 and 1.5.21?

Both Kotlin 1.5.0 and 1.5.21. Also tried AGP 4.2.1 and 4.2.2. Android Studio v4.2.2 but I remember having this issue in earlier versions too.

Have a good rest then! This issue is not a blocker for me in any way.
