No such method error in tests (with Kotest)

I thing something is wrong between Kotest 4.2.4 and Clikt 3.0.1

Then I’m wrtiting this class in the test sources directory:

class ATestCommand : CliktCommand() {
    private val environment: String? by option("-e", "--env")
    override fun run() {
        println("Env: $environment")
    }
}

gives an intellj error on option:

Overload resolution ambiguity: 
public fun ParameterHolder.option(vararg names: String, help: String = ..., metavar: String? = ..., hidden: Boolean = ..., envvar: String? = ..., helpTags: Map<String, String> = ..., completionCandidates: CompletionCandidates? = ..., valueSourceKey: String? = ...): RawOption /* = OptionWithValues<String?, String, String> */ defined in com.github.ajalt.clikt.parameters.options
public fun ParameterHolder.option(vararg names: String, help: String = ..., metavar: String? = ..., hidden: Boolean = ..., envvar: String? = ..., envvarSplit: Regex? = ..., helpTags: Map<String, String> = ..., completionCandidates: CompletionCandidates? = ...): RawOption /* = OptionWithValues<String?, String, String> */ defined in com.github.ajalt.clikt.parameters.options

Same class in source no problem.

Noticed that while was trying to figure out why I can’t run any test on a command.

when I run the test:

class ATestCommandTest() : FunSpec({
    test("test should run without throwing NoSuchMethodError") {
        ATestCommand().parse(emptyArray())
    }
})

I got the error:

'com.github.ajalt.clikt.parameters.options.OptionWithValues com.github.ajalt.clikt.parameters.options.OptionWithValuesKt.option$default(com.github.ajalt.clikt.core.ParameterHolder, java.lang.String[], java.lang.String, java.lang.String, boolean, java.lang.String, java.util.Map, com.github.ajalt.clikt.completion.CompletionCandidates, java.lang.String, int, java.lang.Object)'
java.lang.NoSuchMethodError: 'com.github.ajalt.clikt.parameters.options.OptionWithValues com.github.ajalt.clikt.parameters.options.OptionWithValuesKt.option$default(com.github.ajalt.clikt.core.ParameterHolder, java.lang.String[], java.lang.String, java.lang.String, boolean, java.lang.String, java.util.Map, com.github.ajalt.clikt.completion.CompletionCandidates, java.lang.String, int, java.lang.Object)'

This does not happen if I use JUnit 5 in place of Kotest.

My build.gradle.kts (useful parts)

plugins {
    application
    kotlin("jvm") version "1.4.10"
}
// ...
dependencies {
    implementation("com.github.ajalt.clikt:clikt:3.0.1")
    implementation("com.typesafe:config:1.4.0")

    testImplementation("io.kotest:kotest-runner-junit5:4.2.4") // for kotest framework
    testImplementation("io.kotest:kotest-assertions-core:4.2.4") // for kotest core jvm assertions
    testImplementation("io.kotest:kotest-property:4.2.4") // for kotest property test
    testImplementation("io.mockk:mockk:1.10.0")
}
// ...
tasks.withType<KotlinCompile>() {
    kotlinOptions.jvmTarget = "11"
}

tasks.withType<Test>() {
    useJUnitPlatform()
}
// ...

Thanks

Another option is to bump to kotest 4.3.1 which should require no changes, and works with any version of clickt.

@sksamuel Yup, that also seems to work!
