java - 在 IntelliJ 中而不是在命令行上运行 JUnit 5 测试时出错

Question

当我尝试在 IntelliJ 中运行一个简单的 JUnit 5 测试时报告了以下错误:

这是我的pom:

我正在使用 Intellij v2017.1.2。

当我从命令行运行测试时，没有报告任何错误。

我看到各种帖子报告了不同版本的 IntelliJ 的类似问题，但建议的解决方案没有帮助。

JUnit User Guide建议使用 2017.3 或更新版本。

IntelliJ IDEA releases prior to IDEA 2017.3 bundle specific versions of JUnit 5. Thus, if you want to use a newer version of JUnit Jupiter, execution of tests within the IDE might fail due to version conflicts.
