Gradle integration test task for Kotlin classes - kotlin

Question

I have a Gradle project with Kotlin with 3 source folders (main, test, integration). I want to set up different Gradle test tasks for unit and integration tests. That what those test and integration folders are for. I tried several solutions to set up integration test task but nothing worked so far. It's mentioned everywhere that I need to create a different sourceSet for integration, add some configuration to be able to compile the code in that folder properly and set up the task itself. It's all done, but when I run the tests, they fail. The report then says ClassNotFound for everything basically what is inside that(integration) folder.
build.gradle file and the output results are attached below

It's weird though that the failed task refers to classes/java/integration folder (which does't exist) instead of classes/kotlin/integratin folder, which does exist and this is where the compiled code resides in.

Answer 1

It was my bad. After I moved the code from test to integration folder, some resources inside (those which are responsible for initializing the classes) were pointing to the old directory test, not integration. The Gradle build file is correct.
