Test framework quit unexpectedly

[jakob-grabner]

When I try to run a test i get the following exception. Running the test with the junit (@RunWith(JUnitPlatform::class)) does work.

Exception in thread "main" java.lang.ClassNotFoundException: org.jetbrains.spek.tooling.MainKt

That's weird, it seems you're missing some classes in the plugin. Can you provide your setup? If your using gradle/maven, please provide a build script :)

I'm also receiving the same error message, but not receiving any stack trace, just a red, flagged message in the testing console of IntelliJ. Using @RunWith(...) doesn't alter the issue, either, but it seems that I can run individual tests, yet am unable to use the 'package' feature, meaning testing has to be performed on a per-file basis.

This is the contents of my build.gradle;

buildscript {
    ext.kotlin_version = '1.1.4'

    repositories {
        mavenCentral()
        jcenter()
        maven { url 'https://plugins.gradle.org/m2/' }
        maven { url "http://dl.bintray.com/jetbrains/spek" }
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'org.jetbrains.dokka:dokka-gradle-plugin:0.9.14'
        classpath 'org.junit.platform:junit-platform-gradle-plugin:1.0.0-M4'
    }
}

    id 'idea'
    id 'java'
