How to print to Jenkins' console report the messages from failed asserts?

My FullStack tests run on Jenkins and output nothing on success, otherwise the test name and the failed line. This tells nothing about what went wrong.

Is there a way to print the assertion error message on the Jenkins console?

I have a TestWatcher that already takes a screenshot. Should it also do a System.out.println(e.getMessage())?

I want it to print something like this:

java.lang.AssertionError: Page is listing a different job
Expected: <true>
     but: was <false>
