Question

我刚刚创建了一个示例测试用例，可以与JUnit测试一起很好地运行。我右键单击该项目，然后选择run as --> JUnit test。

但是，我添加了maven surefire插件以使用maven运行相同的插件。但是run as --> Maven test失败，并出现以下错误。

如果您使用JUnit 5，则必须确保以下几点：

使用最新版本的Eclipse（Oxygen 1a中添加了对JUnit 5的支持，但是您应该使用最新版本，例如：2020.03）。
至少使用maven-surefire-plugin中显示的JUnit 5 documentation here的2.22.2版本。
不要自己指定版本：像在junit-bom中所做的那样，在dependencyManagement中使用spring-cloud-dependencies。

<dependencyManagement>
  <dependencies>    
    <dependency>
      <groupId>org.junit</groupId>
      <artifactId>junit-bom</artifactId>
      <version>5.6.1</version>
      <scope>import</scope> <type>pom</type>
    </dependency>
  </dependencies>
<dependencyManagement>

合理性很简单，并且可以解释您的错误：使用junit-bom，您可以确保使用的依赖项是针对同一版本编译的：

junit.jupiter.version是5.4.0
junit-platform-launcher是1.5.1

从central中，我们可以看到引擎正在使用junit-platform-engine的1.4.0：您可能会引入Maven构建的不兼容性，这可能会导致您报告的错误（这样的方法：org.junit.platform.launcher.TagFilter.includeTags（List）PostDiscoveryFilter / invokeStatic ）。
