ID为“junit-vintage”的TestEngine未能发现测试- JUnitException:未能解析junit:junit: 4.13.2

Question

我的Gradle配置和JUnit有一个非常奇怪的问题，我尝试更新到5.7+，但是我得到了以下例外：

org/junit/jupiter/api/extension/ScriptEvaluationException
java.lang.NoClassDefFoundError: org/junit/jupiter/api/extension/ScriptEvaluationException

顺便说一下，我的分级版本是6.8.3。另一方面，这里是我在下面的当前配置中得到的一个例外，我尝试了很多版本和库的组合，但是它们似乎都不起作用：

有人知道怎么做吗？

谢谢你的帮助。

Answer 1

由于JUnit中有一个bug，junit-vintage-engine:5.6.2不支持JUnit 4.13.2。它只支持4.12或4.13。所以你才会看到这个例外。

这个bug是在JUnit 5.6.3中修复的。详情请参见https://github.com/junit-team/junit5/issues/2198。

您还混合了JUnit 5工件的版本，您应该尽量避免这种情况。例如，如果您想使用JUnit平台1.7.2，我建议您使用JUnit木星5.7.2和JUnit Vintage 5.7.2。

有关如何使用Spring正确配置JUnit版本的详细信息，请参阅第5级JUnit BOM和Spring错误版本。

Answer 2

我也犯了这个错误。在我的idea项目文件中，我声明了两个版本的junit依赖项，分别为5.4.2和4.13.2。摆脱4.13.2为我解决了这个问题。

Answer 3

我通过添加spring文档中建议的依赖来解决这个问题：

<dependency>
    <groupId>org.junit.vintage</groupId>
    <artifactId>junit-vintage-engine</artifactId>
    <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>org.hamcrest</groupId>
            <artifactId>hamcrest-core</artifactId>
        </exclusion>
    </exclusions>
</dependency>
