Micronaut Kotlin tests not working when running from Intellij

Question

I am creating a simple todo application using Micronaut and Kotlin. Here is my repository. https://github.com/faskan/todo-micronaut-kotlin

Note that this is a code generated by micronaut launch and I haven't made any changes in it. Following the documentation , I have enabled annotation processors and was expecting my tests to run in Intellij but it doesn't. I have this problem only with Kotlin, with Java as language the tests works fine. A screenshot of my intellij settings. Screenshot of Intellij settings

I have tried adding dagger-compiler annotation processor in to my maven execution configuration. But no help. Appreciate any help to find what the problem is.

Stacktrace:

org.junit.jupiter.engine.execution.ConditionEvaluationException: Failed to evaluate condition [io.micronaut.test.extensions.junit5.MicronautJunit5Extension]: @MicronautTest used on test but no bean definition for the test present. This error indicates a misconfigured build or IDE. Please add the 'micronaut-inject-java' annotation processor to your test processor path (for Java this is the testAnnotationProcessor scope, for Kotlin kaptTest and for Groovy testCompile). See the documentation for reference: https://micronaut-projects.github.io/micronaut-test/latest/guide/

The docs say to add micronaut-core dependency:

<dependency>
    <groupId>io.micronaut</groupId>
    <artifactId>micronaut-core</artifactId>
    <version>3.0.0-M2</version>
    <scope>runtime</scope>
</dependency>

dependency to project and micronaut-inject-java :

<annotationProcessorPaths>
    <path>
        <groupId>io.micronaut</groupId>
        <artifactId>micronaut-inject-java</artifactId>
        <version>3.0.0-M2</version>
    </path>
</annotationProcessorPaths>

to annotation processor path.

Answer 2

The IntelliJ compiler doesn't allow running annotation processors for Kotlin with KAPT so you have to delegate to Gradle or Maven for the build

We have reported this many times to JetBrains but unfortunately they don't seem interested in improving the user experience for Kotlin users that use KAPT
