[英]Failed to execute junit5 tests with dependency management with spring boot gradle plugin
在基于gradle和kotlin的项目中,我有一些子模块。 为它构建配置模块(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")
}
我尝试在此模块中运行一些简单的测试
简单类:
class Hello {
fun hello(): String {
return "hello"
}
}
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” ,并将使用像这样的spring boot版本compile(“ org.springframework.boot:spring-boot-starter -web:2.1.5.RELEASE“)测试正确运行。
Spring依赖管理破坏了我的junit5测试。 请谁能解释为什么会这样以及如何解决问题? 谢谢!
似乎添加Spring Dependency Management会更改junit-jupiter依赖项的某些传递依赖项。
您声明的junit版本(5.4.2)取决于junit-platform-commons 1.4.2,但是当您添加Spring Dependency Management时,它会将commons版本从1.4.2更改为1.3.2。 这就是为什么您收到NoSuchMethodError的原因,因为该方法是在第四版中添加的!
我可以想到以下两个解决方案:
1)(我建议这样做)删除声明的junit版本,并让Spring Dependency Management处理junit的所有内容:
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(如果这是必不可少的,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")
