java.lang.NoClassDefFoundError: org/junit/platform/launcher/TestExecutionListener

I am trying to create a test class (JUnit 5) using Intellij Idea but I get the bellow error. When I created the test class it did NOT show the fix button so I am pretty sure the library is in class path.

Exception in thread "main" java.lang.NoClassDefFoundError: org/junit/platform/launcher/TestExecutionListener

    ... 13 more

My build.gradle looks as below:

plugins {
    id 'java'
    id 'application'
    id 'org.openjfx.javafxplugin' version '0.0.7'
}

group 'ict221'
version '1.0-SNAPSHOT'
sourceCompatibility = 1.11
mainClassName = 'boardgame.gui.RunGame'

repositories {
    mavenCentral()
}

test {
    useJUnitPlatform()
}

dependencies {
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.3.1'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.3.1'
}

javafx {
    modules = [ 'javafx.controls', 'javafx.fxml' ]
    version = "11.0.2"
}

Any help is much appreciate it.

Adding just the junit-platform-launcher worked for me

     <dependency>
       <groupId>org.junit.platform</groupId>
       <artifactId>junit-platform-launcher</artifactId>
       <version>1.7.2</version>
       <scope>test</scope>
     </dependency>

testImplementation group: 'org.junit.platform', name: 'junit-platform-launcher', version: '1.7.2'

Below is an example of a build.gradle for a simple application with JDK 17, Gradle 7.5.1 and JUnit Jupiter 5.9.0, which causes IntelliJ IDEA to correctly run unit tests with JUnit.

Notice that there is no need to add test dependencies as it is done automatically by configuring testing section.

build.gradle

plugins {
    id 'application'
}

group = 'your.app'
version = '0.0.1'
sourceCompatibility = '17'

repositories {
    mavenCentral()
}

dependencies {
}

testing {
    suites {
        test {
            useJUnitJupiter('5.9.0')
        }
    }
}

application {
    mainClass = 'your.app.App'
}

src/main/test/your/app/AppTest.java

package your.app;

import org.junit.jupiter.api.Test;

class AppTest {

    @Test
    void testFeature() {
    }
}

As mentionned by @CrazyCode in comments, with Intellij you need to specify the version of JUnit (because Intellij is bundled with old version of JUnit)

Add this : 

dependencies {
    ...
    testRuntimeOnly("org.junit.platform:junit-platform-launcher:1.6.1")
    testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine:5.6.1")
    testRuntimeOnly("org.junit.vintage:junit-vintage-engine:5.6.1")
}
