JUnit 5和Mockito [英] JUnit 5 and Mockito

问题描述

在Java 14和JUnit 5中，如果我在我的构建中添加了嘲笑-junit-jupiter，即使在任何测试中都没有使用嘲笑，尝试运行mvn测试时也会引发错误.不用mockito-junit-jupiter一切都很好.除Maven之外，所有依赖项均为最新版本.

With Java 14 and JUnit 5, if I add mockito-junit-jupiter to my build, an error is thrown when trying to run mvn test even without using mockito in any tests. Wiithout mockito-junit-jupiter everything is okay. All dependencies are the latest versions except Maven.

抛出的错误是

推荐答案

在混合JUnit 5和Mockito时，Maven依赖项的顺序似乎很重要. Mockito依赖项必须紧随JUnit 5的依赖项.也许它仅是mockito-junit-jupiter的依赖项，但是我尝试将它们组合在一起.

The order of Maven dependencies seems to be important when mixing JUnit 5 and Mockito. The Mockito dependencies MUST come after the ones for JUnit 5. Maybe it is only the one for mockito-junit-jupiter, but I try to group them toegether.
