在 IntelliJ 中运行 JUnit 5 测试但不在命令行上运行时出错

Question

当我尝试在 IntelliJ 中运行简单的 JUnit 5 测试时，报告以下错误：

这是我的 pom：

我使用的是 Intellij v2017.1.2。

当我从命令行运行测试时，没有报告错误。

我见过各种帖子报告不同版本的 IntelliJ 的类似问题，但建议的解决方案没有帮助。

JUnit用户指南建议使用 2017.3 或更高版本。

IntelliJ IDEA 在 IDEA 2017.3 之前发布，捆绑特定版本的 JUnit 5。因此，如果您想使用较新版本的 JUnit Jupiter，IDE 中的测试执行可能会因版本冲突而失败。
