Assertions.kt assertDoesNotThrow() breaks with IllegalAccessError in JUnit 6 #5062
Description
Given a Gradle project that looks like this (built with Temurin 24):
plugins {
kotlin("jvm") version "2.2.20"
}
group = "org.example"
version = "1.0-SNAPSHOT"
repositories {
mavenCentral()
}
dependencies {
testImplementation("org.junit.jupiter:junit-jupiter:6.0.0")
testRuntimeOnly("org.junit.platform:junit-platform-launcher:6.0.0")
// testImplementation("org.junit.jupiter:junit-jupiter:5.14.0")
// testRuntimeOnly("org.junit.platform:junit-platform-launcher:1.14.0")
}
tasks.test {
useJUnitPlatform()
}And a test file like this:
import org.junit.jupiter.api.Test
import org.junit.jupiter.api.assertDoesNotThrow
class Test {
@Test
fun test() {
assertDoesNotThrow {
error("but it does")
}
}
}The following exception is produced:
failed to access class org.junit.jupiter.api.AssertDoesNotThrow from class Test (org.junit.jupiter.api.AssertDoesNotThrow and Test are in unnamed module of loader 'app')
java.lang.IllegalAccessError: failed to access class org.junit.jupiter.api.AssertDoesNotThrow from class Test (org.junit.jupiter.api.AssertDoesNotThrow and Test are in unnamed module of loader 'app')
at Test.test(Test.kt:17)
Swapping to the commented out dependencies with the previous releases produces the correct assertion failed error:
Unexpected exception thrown: java.lang.IllegalStateException: but it does
org.opentest4j.AssertionFailedError: Unexpected exception thrown: java.lang.IllegalStateException: but it does
