无法使用 spring 引导 gradle 插件执行依赖管理的 junit5 测试
Failed to execute junit5 tests with dependency management with spring boot gradle plugin
在我基于 gradle 和 kotlin 的项目中，我有一些子模块。为 it 模块构建配置（build.gradle.kts）：
plugins {
java
kotlin("jvm")
id("org.springframework.boot") version "2.1.5.RELEASE"
id("io.spring.dependency-management") version "1.0.7.RELEASE"
}
dependencies {
compile("org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.3.31")
compile("org.springframework.boot:spring-boot-starter-web")
testCompile("org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.3.31")
testCompile("org.jetbrains.kotlin:kotlin-stdlib:1.3.31")
testCompile("org.jetbrains.kotlin:kotlin-reflect:1.3.31")
testImplementation("org.junit.jupiter:junit-jupiter-api:5.4.2")
testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine:5.4.2")
}
我尝试运行在这个模块中进行一些简单的测试
简单class：
class Hello {
fun hello(): String {
return "hello"
}
}
对其进行简单测试：
class HelloTest {
@Test
fun test() {
Assertions.assertEquals(Hello().hello(), "hello")
}
}
当我尝试 运行 测试时出现错误：

但是如果从我的构建配置中删除 id("io.spring.dependency-management") 版本“1.0.7.RELEASE” 并且将使用 spring 版本像这样启动 compile("org.springframework.boot:spring-boot-starter-web:2.1.5.RELEASE") 正确测试 运行s。
Spring 依赖管理破坏了我的 junit5 测试。请问谁能解释为什么会这样以及如何解决这个问题？谢谢！
似乎添加 Spring 依赖管理会更改 junit-jupiter 依赖项的一些传递依赖项。
您声明的 junit 版本 (5.4.2) 依赖于 junit-platform-commons 1.4.2，但是当您添加 Spring 依赖管理时，它会将通用版本从 1.4.2 更改为 1.3.2 .这就是您收到 NoSuchMethodError 的原因，因为该方法是在第四版中添加的！
以下是我能想到的两种解决方案：
1)（我推荐这个）删除你声明的 junit 版本，让 Spring 依赖管理处理 junit 的一切：
testImplementation("org.junit.jupiter:junit-jupiter-api")
testRuntime("org.junit.jupiter:junit-jupiter-engine")
2) 声明 junit 的传递依赖版本（如果这是 must-have，这将允许您继续使用版本 5.4.2）
testImplementation("org.junit.jupiter:junit-jupiter-api:5.4.2")
testImplementation("org.junit.platform:junit-platform-commons:1.4.2")
testRuntime("org.junit.jupiter:junit-jupiter-engine:5.4.2")
testRuntime("org.junit.platform:junit-platform-engine:1.4.2")
