maven正在尝试运行Serenity JBheave时遇到“java.lang.NoClassDefFoundError:org/junit/platform/engine/DiscoverySelector”

Question

使用Maven（通过命令行）创建了一个新的通用Serenity BDD JBehave框架

已将项目导入Intelli J，但当我尝试运行“AcceptanceTestSuite”时，我收到一个错误，显示“未找到任何测试”，并出现以下错误Exception in thread "main" java.lang.NoClassDefFoundError: org/junit/platform/engine/DiscoverySelector

我尝试重新导入项目，但这并不能解决问题

以下是完整的错误日志：

Answer 1

如果不使用maven，Junit 5的依赖项是：

JUnitJupiter api

朱尼特木星发动机

junit平台引擎

junit平台共享

junit vintage引擎（可选）

他们可以找到： https://junit.org/junit5/

Answer 2

在我的例子中，我们正在使用gradle，不知何故，我无法解决它，我已经在eclipse中手动添加了JAR，现在它可以工作了。 在Eclipse项目中→ 构建路径→ 配置生成路径->；图书馆→ 添加与“jupiterEnginer5.5”相关的所有库。 以下是“jupiterEnginer5.5”的所有JAR：opentest4j-1.2.0。jarjunit-platform-engine-1.7.0-M1。jarjunit-platform-commons-1.7.0-M1。jar junit-jupiter-engine-5.7.0-M1。jarjunit-jupiter-api-5.7.0-M1。jar-api-api-1.1.0。罐子

Answer 3

向pom.xml添加依赖项：

<dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-engine</artifactId>
    <version>1.2.0</version>
</dependency>
