【问题描述】：
我有一个简单的项目，我希望能够同时运行 JUnit 5 单元测试和 Spock 2 功能测试。如果我在下面的 build.gradle 中注释掉了 Spock 依赖项，我的 JUnit5 测试就会运行并通过。但是，如果我取消注释 Spock 依赖项以准备添加 Spock 测试，则 JUnit5 测试开始失败。
我的 build.gradle：
buildscript {
repositories {
maven { url "https://plugins.gradle.org/m2/" }
}
dependencies {
classpath(
"org.springframework.boot:spring-boot-gradle-plugin:2.1.6.RELEASE",
'net.researchgate:gradle-release:2.8.0'
)
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
apply plugin: 'net.researchgate.release'
apply plugin: 'groovy'
repositories {
mavenCentral()
jcenter()
}
sourceCompatibility = 11
targetCompatibility = 11
dependencies {
implementation 'org.springframework.boot:spring-boot-starter'
implementation("org.springframework.boot:spring-boot-starter-web")
implementation("org.springframework.boot:spring-boot-starter-actuator")
testImplementation('org.springframework.boot:spring-boot-starter-test') {
exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}
testImplementation 'org.codehaus.groovy:groovy:3.0.5'
testImplementation group: 'org.spockframework', name: 'spock-spring', version: '2.0-M3-groovy-3.0'
testImplementation group: 'org.spockframework', name: 'spock-core', version: '2.0-M3-groovy-3.0'
//testImplementation group: 'org.spockframework', name: 'spock-junit4', version: '2.0-M3-groovy-3.0'
testImplementation 'org.junit.jupiter:junit-jupiter-api:5.3.1'
testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.3.1'
}
test {
useJUnitPlatform()
}
jar {
enabled = true
}
bootJar {
archiveFileName = "app.jar"
}
如果我取消注释 Spock 依赖项会出现错误：
