java - JUnit 5 和 Mockito

Question

使用 Java 14 和 JUnit 5，如果我将mockito-junit-jupiter 添加到我的构建中，即使在任何测试中不使用mockito，尝试运行 mvn 测试时也会引发错误。没有mockito-junit-jupiter一切都好。除 Maven 外，所有依赖项均为最新版本。

抛出的错误是

Answer 1

混合 JUnit 5 和 Mockito 时，Maven 依赖项的顺序似乎很重要。 Mockito 依赖项必须位于 JUnit 5 的依赖项之后。也许它只是mockito-junit-jupiter 的依赖项，但我尝试将它们组合在一起。
