all my jUnit tests in Jenkins return same error related to StackTraceCleanerProvider method isIn()

Question

I inherited a Spring project that has about 160 failing JUnit Tests with Mockito classes

When I check in Jenkins, I see that every single test has the following Error details:

Receiver class org.powermock.api.mockito.internal.exceptions.StackTraceCleanerProvider$1 does not define or inherit an implementation of the resolved method 'abstract boolean isIn(java.lang.StackTraceElement)' of interface org.mockito.exceptions.stacktrace.StackTraceCleaner.

and the stacktrace is:

I cannot find anything related to this error or exception.

I have no config access to the jenkins job, but I have the feeling that the used junit oder Mockito version in Jenkins is outdated.
When I run the tests locally per IntelliJ, i do not get the error.

Answer 1

The error message is saying that org.powermock.api.mockito.internal.exceptions.StackTraceCleanerProvider$1 does not provide an implementation for the isIn method, which is an abstract method in org.mockito.exceptions.stacktrace.StackTraceCleaner. This typically happens when the versions of PowerMock and Mockito being used are not compatible, and one of them (usually PowerMock) is relying on an outdated method signature.

As a solution:

1. Remove PowerMock if Possible: If you can, try using Mockito's built-in features to avoid PowerMock altogether. Mockito 3.x and above now support mocking static methods, constructors, and final classes, reducing the need for PowerMock.

2. Downgrade Mockito Version: If updating PowerMock is not an option, you can try downgrading Mockito to a version that is compatible with the version of PowerMock you are using.
