java.lang.NoSuchMethodError: org.mockito.Answers.get()Lorg/m

Question

我正在尝试将spring boot版本从2.2.4升级到2.6.6。我能够成功地编译应用程序，并且能够启动应用程序。但是当我试图运行测试时，所有的测试都失败了，出现了一个错误:

. lang。NoSuchMethodError: org.mockito.Answers.get () Lorg 5/stub/答案;

我所有的测试都得到相同的错误。

Answer 1

似乎你的Powermock库与Mockito冲突。

您可以在您的pom.xml中尝试以下依赖版本和顺序。注意，主要思想是优先考虑Mockito而不是Powermock

<dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-core</artifactId>
<version>2.10.0</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-mockito2</artifactId>
<version>2.0.2</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit4</artifactId>
<version>2.0.2</version>
<scope>test</scope>
</dependency>
