Answer 1

SYMPTOM: Error when run maven with Jmockit and junit into java project.

MESSAGE: JMockit wasn't properly initialized; check that jmockit.jar precedes junit.jar in the classpath (if using JUnit; if not, check the documentation)

CAUSES:

Wrong configured in POM.xml file. Jmockit dependencyis is after of junit.

SOLUTIONS:

Edit POM.xml file. The jmockit.jar should be precedes junit.jar then jmockit dependency should be before of junit.
