【问题描述】：

我有一个演示 springboot 应用程序并尝试使用 gradle 运行 cucumber 测试用例。在 maven 中它工作正常但无法使用 gradle 运行。 你能帮我从eclipse或命令行执行gradle文件的方法吗

下面是mt build.gradle文件

       testImplementation 'io.cucumber:cucumber-junit:5.3.0'
    testImplementation 'io.cucumber:cucumber-core:5.3.0'
    testImplementation 'io.cucumber:cucumber-spring:5.3.0'
    testImplementation 'io.cucumber:cucumber-java:5.3.0'
    testImplementation 'javax.xml.bind:jaxb-api:2.2.8'
    testImplementation 'org.mockito:mockito-core:1.9.5' 
    testImplementation 'junit:junit:4.12'
    testImplementation('org.springframework.boot:spring-boot-starter-test')
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    
    implementation ('org.springframework.boot:spring-boot-starter-actuator')
    exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
    exclude group: 'org.springframework.boot', module: 'spring-boot-starter-log4j2'     
        
    

test
testLogging.showStandardStreams = true



sourceSets 
   main.java.srcDir "src/main/java"
   main.resources.srcDir "src/main/resources"
   test.java.srcDir "src/test/java/com/b**/f**/w**/tests"
   test.resources.srcDir "src/test/resources"


    configurations 
    cucumberRuntime 
        extendsFrom testImplementation
    




task cucumber() 

    dependsOn assemble, compileTestJava , testClasses

    doLast 

        javaexec 

            main = "cucumber.api.cli.Main"

            classpath = configurations.cucumberRuntime + sourceSets.main.output + sourceSets.test.output

            args = ['--plugin', 'pretty', '--glue', 'com.b**.f**.w**.tests', 'src/test/resources']

        

    

下面是我在命令行中使用“Gradle cucumber”执行时的错误

【问题讨论】：

可以试试黄瓜版v5.4.21吗？

【参考方案1】：

我遇到了与您类似的问题，但 Gradle 不会运行我的 Junit 5 + Cucumber 测试。看起来 Cucumber 没有任何 Junit 5 支持，所以我不得不恢复到 Junit 4（也称为 Junit 5 年份）。

我的诀窍是在我的build.gradle 中启用旧版 Junit 支持。

test 
  // Use old (Junit 4) runner since Cucumber doesn't support Junit 5 *sigh*
  useJUnit()
  // useJUnitPlatform()

我的代码/设置的重置：

build.gradle

plugins 
  id 'org.springframework.boot' version '2.2.1.RELEASE'
  id 'io.spring.dependency-management' version '1.0.8.RELEASE'
  id 'java'


group = 'se.snorbu.cucumber'
version = '0.0.1-SNAPSHOT'
configurations 
  compileOnly 
    extendsFrom annotationProcessor
  


repositories 
  // Use jcenter for resolving dependencies.
  // You can declare any Maven/Ivy/file repository here.
  jcenter()


dependencies 
  // Spring
  implementation 'org.springframework.boot:spring-boot-starter-web'
  implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'

  // Cucumber
  testCompile 'io.cucumber:cucumber-java:6.6.0'
  testCompile 'io.cucumber:cucumber-junit:6.6.0'
  testCompile 'io.cucumber:cucumber-spring:6.6.0'
  testCompile 'io.cucumber:cucumber-junit-platform-engine:6.6.0'

  // Misc
  testCompileOnly 'org.projectlombok:lombok'
  testAnnotationProcessor 'org.projectlombok:lombok'

  // Junit5
  testImplementation('org.springframework.boot:spring-boot-starter-test') 
    exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
  


test 
  // Use old (Junit 4) runner since Cucumber doesn't support Junit 5 *sigh*
  useJUnit()
