我尝试在我的maven项目中运行Junit 5测试,但出现错误:TestEngine with ID 'junit-jupiter' failed to discover tests。junit-jupiter-engine版本是5.9.0(也尝试过其他版本),maven-surefire-plugin版本是2.22.2。
我正在使用Intellij社区版(2023.1.3)
获取以下错误:

我试着改变junit-jupiter-engine的版本,但没有帮助。有人能帮我吗?

查看您的pom,您有以下依赖项:

  • kotlin-test-junit5:1.7.10依赖于junit-jupiter-api:5.6.0
  • junit-jupiter-engine:5.8.2依赖于junit-jupiter-api:5.8.2

而类org.junit.jupiter.api.ClassOrderer只在junit-jupiter-api:5.8.0中引入。
所以这里有两个依赖项,它们都对junit-jupiter-api有一个传递依赖项,但是它们依赖于不同的版本。Maven有一个算法来解决这个版本冲突,我认为它决定使用junit-jupiter-engine:5.8.2(因为它是由你的pom显式引入的)和junit-jupiter-api:5.6.0(* 参见底部的注解1)-这可以使用mvn dependency:tree -Dverbose检查,看看它说了什么。
为了解决这个冲突,我简单地从你的pom中删除junit-jupiter-engine,因为它是由kotlin-test-junit5带来的。这应该解决了我认为的问题。
作为一个旁注,您可以使用Maven Enforcer plugin,它的目标是确保所有依赖项(包括可传递的)converge到同一个版本。
备注:
1.我认为这是因为它在kotlin-test-junit5junit-jupiter-engine中都是深度为1的传递依赖,但是kotlin-test-junit5是第一个,所以这是最终使用的版本。
