Я бегу grails 2.4.4 локально. У меня есть следующий класс домена:grails бросает исключение при запуске grails генерировать команды
class MyClass {
byte[] posterImage
String posterType
String posterName
static belongsTo = NicheChannel
static constraints = {
posterImage(nullable: true, maxSize: 16384000 /* 16000k */)
posterType(nullable: true)
}
}
При попытке запуска
grails generate-controller MyClass
или
grails generate-views MyClass
я получаю следующее исключение:

Я даже пытался
grails generate-all MyClass
И я получаю то же исключение.
