NoClassDefFoundError: Mockito Bytebuddy
提问by efong5
I recently added Mockito to a maven project on eclipse, by adding the external jar "mockito-core-2.0.53-beta.jar", and upon attempting to create my first mock object (Line two in the function)
我最近通过添加外部 jar“mockito-core-2.0.53-beta.jar”并尝试创建我的第一个模拟对象（函数中的第二行）将 Mockito 添加到 Eclipse 上的 Maven 项目中
And upon running it, the console prints out the first line, then throws this error:
在运行它时，控制台打印出第一行，然后抛出这个错误：
It seems like previously there was a similar issue, but it was supposedly fixed internally. https://github.com/raphw/byte-buddy/issues/99
之前好像也有类似的问题，但据说是在内部修复的。https://github.com/raphw/byte-buddy/issues/99
What is going wrong here?
这里出了什么问题？

You simply forgot to add the dependencies to your project which are according to the pom file:
您只是忘记根据 pom 文件将依赖项添加到您的项目中：
<dependency>
<groupId>net.bytebuddy</groupId>
<artifactId>byte-buddy</artifactId>
<version>1.3.16</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.objenesis</groupId>
<artifactId>objenesis</artifactId>
<version>2.1</version>
<scope>runtime</scope>
</dependency>
In other words you need to add byte-buddy 1.3.16and objenesis 2.1to your project too.
换句话说，您也需要将byte-buddy 1.3.16和添加objenesis 2.1到您的项目中。

There is a post that explain the problem pretty well, you can find it here:
有一个帖子很好地解释了这个问题，你可以在这里找到它：
If you are not using gradle or maven and you are just using mockit-core you should add these dependencies:
如果你没有使用 gradle 或 maven 而你只是使用 mockit-core，你应该添加这些依赖项：
<dependency>
<groupId>net.bytebuddy</groupId>
<artifactId>byte-buddy</artifactId>
<version>1.7.9</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.objenesis</groupId>
<artifactId>objenesis</artifactId>
<version>2.4</version>
<scope>runtime</scope>
</dependency>

而是添加
mockito-core

java.lang.NoClassDefFoundError
java.lang.NoClassDefFoundError
This indicates that in your .jar (org.mockito), you don't have that class. This usually occurs when you have more than one .jar (with a different version) in your classpath. You could check that.
这表明在您的 .jar (org.mockito) 中，您没有那个类。当您的类路径中有多个 .jar（具有不同版本）时，通常会发生这种情况。你可以检查一下。
