[ERROR] Line 97: ConstraintViolation cannot be resolved to a

Add the javax.validation
jar<http://mvnrepository.com/artifact/javax.validation/validation-api/1.0.0.GA>
(jsr303)
and some
implementation<http://stackoverflow.com/questions/1384968/is-there-an-implementation-of-jsr-303-bean-validation-available>
