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)
And upon running it, the console prints out the first line, then throws this error:
It seems like previously there was a similar issue, but it was supposedly fixed internally. https://github.com/raphw/byte-buddy/issues/99
What is going wrong here?
You simply forgot to add the dependencies to your project which are according to the pom file:
<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 1.3.16 and objenesis 2.1 to your project too.
More details here
There is a post that explain the problem pretty well, you can find it here:
If you are not using gradle or maven and you are just using mockit-core you should add these dependencies:
<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> Instead adding
mockito-core
better option will to add
mockito-all
Refer to this link https://mvnrepository.com/artifact/org.mockito/mockito-all/2.0.2-beta
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.
