Junit 5 console launcher

Help/Discuss
1

Java and gradle novice here. I have a project with two subprojects: a Java application 00 and a Java library 01. I am using the JUnit 5 to test the library 01. Below is the build script that I am using. It works: if I do “gradle” in the root project dir, it does run on subproject 00 and build on subproject 01; the latter produces some test results as expected, but the output format of the test results is plain, and looks only like test foo PASSED. I want to use the JUnit Console Launcher, so that I get better output from the tests. How do I change the build script for that? Thanks.

val applicationSubprojects: List<String> = listOf("00")

fun mainTaskName(subproject: String): String =
  if(subproject in applicationSubprojects) "run" else "build"

allprojects {
  repositories {
    jcenter()
  }
  task("make")
  defaultTasks("make")
}

subprojects {
  apply(plugin = "java")
  if(project.name in applicationSubprojects) {
    apply(plugin = "application")
  }
  dependencies {
    "testImplementation"(
      group = "org.junit.jupiter",
      name = "junit-jupiter",
      version = "5.5.0-M1"
    )
  }
  tasks.named("make") {
    dependsOn(mainTaskName(project.name))
  }
  tasks.named<Test>("test") {
    useJUnitPlatform()
    testLogging {
      events("passed", "skipped", "failed")
      showStandardStreams = true
      setExceptionFormat("full")
    }
  }
}

project(":00") {
  configure<ApplicationPluginConvention> {
    mainClassName = "net.retrotexts.aj.lesson00.Hello"
  }
}

I have tried some changes following the Junit5 project build script. However, when I do gradle, I get an error “classpath = sourceSets[“test”].runtimeClasspath … Unresolved reference: sourceSets”. Where is the name sourceSets, and what do I have to import to use it? My current build.gradle.kts is as below. Thanks.

val applicationSubprojects: List<String> = listOf("00")

fun mainTaskName(subproject: String): String =
  if(subproject in applicationSubprojects) "run" else "build"

allprojects {
  repositories {
    jcenter()
  }
  task("make")
  defaultTasks("make")
}

  apply(plugin = "java")
  if(project.name in applicationSubprojects) {
    apply(plugin = "application")

    "testRuntimeOnly"(
      group = "org.junit.platform",
      name = "junit-platform-console",

    }
    dependsOn("consoleLauncherTest")
  }
  task<JavaExec>("consoleLauncherTest") {
    dependsOn("testClasses")
    val reportsDir: File = file("$buildDir/test-results")
    outputs.dir(reportsDir)

    main = "org.junit.platform.console.ConsoleLauncher"
