You posted the same question about Bamboo. Bamboo is a continuous integration server and JIRA is a defect reporting tool. I'm guessing there is some integration that Bamboo cuts a JIRA ticket on build failures. Regardless, troubleshooting is the same.
ESFormTest sounds like it has an import for mockito and mockito isn't on the classpath. How is your classpath set? Eclipse? Ant? Maven?
