Cannot use this plugin in tandem with Kotlin Multiplatform Tests #116

We got a report from one of our users that was having trouble running the test retry plugin with a kotlin project. After some digging, we found that org.jetbrains.kotlin.multiplatform.gradle.plugin creates their own test executer for KotlinJvmTest per https://github.com/JetBrains/kotlin/blob/master/libraries/tools/kotlin-gradle-plug[…]/org/jetbrains/kotlin/gradle/targets/jvm/tasks/KotlinJvmTest.kt When this happens, this part of the test retry plugin is reached: https://github.com/gradle/test-retry-gradle-plugin/blob/v1.3.1/plugin/src/main/java/org/gradle/testretry/internal/config/TestTaskConfigurer.java#L142 so tests fail with the following:

> Configure project :
Kotlin Multiplatform Projects are an Alpha feature. See: https://kotlinlang.org/docs/reference/evolution/components-stability.html. To hide this message, add 'kotlin.mpp.stability.nowarn=true' to the Gradle properties.

> Task :jvmTest FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':jvmTest'.
> Unexpected test executer: org.jetbrains.kotlin.gradle.targets.jvm.tasks.KotlinJvmTest$Executor@1073de17
