in a multiplatform project gradle build (kotlin dsl) how can i create a JavaExec task that has the jvmTest classpath? in the jvm only build it was just classpath = sourceSets["test"].runtimeClasspath

[ephemient]

configurations["jvmTestRuntimeClasspath"] should be what you want unless you've named the JVM target something else or created a separate test compilation

[ephemient]

but it feels somewhat unusual to be creating a JavaExec from that - what are you trying to do?

[ephemient]

if you want to include the test classes themselves and not just its runtime dependencies, you can hook into

kotlin {
    targets {
        jvm {
            compilations.getByName("test") {
                tasks.register<JavaExec>("myJavaExecTask") {
                    classpath(runtimeDependencyFiles, output)

but if what you're trying to do is create another test task, you should use Test instead of JavaExec

thanks that works. its part of my test runner that I’m converting to multiplatform as an experiment. it can run tests via junit engine but also as main method.

[ephemient]

the right thing to do, long-term, may be to add the test framework to Gradle itself. unfortunately that's not currently a public API :-/

[christophsturm]

right. but running test as main method can be pretty useful to get it running on all kotlin supported platforms. its also only an experiment. jvm performance matters most for me.

[ephemient]

hmm, curious. https://docs.gradle.org/current/javadoc/org/gradle/api/tasks/testing/Test.html#getTestFrameworkProperty-- looks like it's exposed publicly, but all the stuff connected to it isn't

still lots of things broken. junit engine finds no tests and idea says “kotlin not configured” after importing the project. this branch will probably not be merged soon.
