How to use JUnit 5 with build.gradle.kts and kotlin?

Question

• Java version java 10.0.1 2018-04-17
• Kotlin version 1.2.41
• Gradle version 4.7

it will be even better if we could use jigsaw module system

Answer 1

There's documentation and a sample project for using Gradle and JUnit 5.

If you want to use the Kotlin DSL you'll have to adapt it in the following way:

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

For Jigsaw, Gradle provides experimental support and there's a fork of the plugin that provides additional features.

Answer 2

Marc Philipp's answer works. Here is another approach:

val test: Test by tasks
test.useJUnitPlatform()
