NonExistentClass cannot be converted to Annotation - app:kaptDebugAndroidTestKotlin - kotlin

Question

I want to test a class using JUnit5 but at the time gradle runs the app:kaptDebugAndroidTestKotlin task I get the issue.
I have already tried the solutions in the following links but nothing helps so far:
NonExistentClass cannot be converted to Annotation
error: incompatible types: NonExistentClass cannot be converted to Annotation #error.NonExistentClass()
my project build.gradle file:
buildscript {
ext.kotlin_version = '1.3.40'
ext.anko_version='0.10.8'
ext.junit_version='5.5.0'
repositories {
google()
jcenter()
mavenCentral()

}
}

}

delete rootProject.buildDir
}

and my gradle.properties file:
kotlin.code.style=official
org.gradle.jvmargs=-Xmx1536m
android.useAndroidX=true
android.enableJetifier=true
android.databinding.enableV2=true
I tried to run the test but what I get while compiling is the following:
C:\project_path\app\build\tmp\kapt3\stubs\debugAndroidTest\com\package\test\module\search\SearchPresenterTest.java:20: error: incompatible types: NonExistentClass cannot be converted to Annotation
#error.NonExistentClass()
The file under build folder has some of the following:
#error.NonExistentClass()
public final void setUpMocks() {
}
#error.NonExistentClass()
public final void onSearch() {
}
While the original kotlin test file is like the following lines:
#BeforeEach
fun setUpMocks() {
clearAllMocks()
}
#Test
fun onSearch() {
verify { view.onSearch() }
}

Seems that I mixed some JUnit4 dependencies with those of JUnit5 so by removing the following lines (like the AndroidJUnitRunner class) in the dependencies I got it working:
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
kapt("org.jetbrains.kotlin.kapt:org.jetbrains.kotlin.kapt.gradle.plugin:1.3.31:pom")
And I added back again those of the jupiter packages:
testImplementation "org.junit.jupiter:junit-jupiter-api:$junit_version"
testImplementation "org.junit.jupiter:junit-jupiter-engine:$junit_version"
testImplementation "org.junit.vintage:junit-vintage-engine:$junit_version"
Also the org.junit classes in all the tests have to be replaced by their equivalent of the org.junit.jupiter package.
That made it compile the test without issues.
