Question

我正在尝试使用Intellij Idea创建测试类（JUnit 5），但出现了以下错误。当我创建测试类时，它没有显示“修复”按钮，因此我可以确定该库在类路径中。

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

我的build.gradle如下所示：

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"
}

任何帮助都非常感谢。

Answer 1

@CrazyCode在评论中提到，使用Intellij，您需要指定JUnit的版本（因为Intellij与JUnit的旧版本捆绑在一起）

添加此内容：

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")
}

Answer 2

尝试在 gradle 项目中为 junit5 输入这些依赖

testImplementation("org.junit.jupiter:junit-jupiter-api:5.7.0")
testRuntimeOnly("org.junit.platform:junit-platform-launcher:1.7.2")
testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine:5.7.2")
testRuntimeOnly("org.junit.vintage:junit-vintage-engine:5.7.2")

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