Jenkins unable to generate test report due to NoClassDefFoundError - ParseResultCallable

Question

I set up a Jenkins job to run some integration tests. After testing finishes, Jenkins should look for test report in settings. However, it gives following error:

Recording test results

Here is my Publish Junit result setting:

I checked the path for those xml files in workspace, they do exist. I'm not sure what could be wrong. My JUnit Plugin version is 1.5.

You have a version mismatch between the JUnit version in your build and the version that is loaded into Jenkins. https://issues.jenkins-ci.org/browse/JENKINS-24946 may provide some insight, but in general, you need to be very careful that the versions are compatible.
