FAILURE: Build failed with an exception.

* What went wrong:
Some problems were found with the configuration of task ':macrobenchmark:koverHtmlReport' (type 'KoverHtmlTask').
  - In plugin 'org.jetbrains.kotlinx.kover' type 'kotlinx.kover.gradle.plugin.tasks.reports.KoverHtmlTask' property 'filters' doesn't have a configured value.

    Reason: This property isn't marked as optional and no value has been configured.

    Possible solutions:
      1. Assign a value to 'filters'.
      2. Mark property 'filters' as optional.

Hi,
to generate merged report you just need to call the task only for the root project (where subprojects { is specified) - thus Gradle commands will be gradlew clean :koverHtmlReport (with colon) instead of gradlew clean koverHtmlReport.

However, unfortunately, tests on devices are not supported now, so the report will display coverage 0 for all classes.
