那些遇到过的问题

java.lang.NoSuchMethodError: org.mockito.Answers.get()Lorg/mockito/stubbing/Answer;

Cib*_*iby 4 mockito powermock maven spring-boot vaadin8

我正在尝试将 spring boot 版本从 2.2.4 升级到 2.6.6。我能够成功编译应用程序并且能够启动应用程序。但是当我尝试运行测试时，所有测试都因一个错误而失败：

java.lang.NoSuchMethodError: org.mockito.Answers.get()Lorg/mockito/stubbing/Answer;

我在所有测试中都遇到相同的错误。

您的库似乎Powermock与Mockito.

您可以在 pom.xml 中尝试以下依赖项版本和顺序。注意，主要思想是优先Mockito比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>
