Build fails when used with Kotlin JS plugin.

build.gradle.kts

plugins {
    kotlin("js") version "1.6.21"
    id("de.fuerstenau.buildconfig") version "1.1.8"
}

kotlin {
    js(IR) {
        browser()
    }
}

Exception on the line starting with js(IR) {:

Cannot add task 'testClasses' as a task with that name already exists.

I'm having this with the following:

plugins {
    id("org.kite9.java-conventions")
    kotlin("js") version "1.8.10"
}

kotlin {
    js(IR) {

    }
}
