Что не так?Пожалуйста, помогите ...

Answer 1

Добавление этого в BuildConfig.groovy у меня сработало:

inherits("global") {
  excludes "xml-apis"
}

Answer 2

Это похоже на адский путь к классам ...

Две зависимости связывают один и тот же jar с разными версиями

Проверьте ваши зависимости, найдите виновную банку (которая, похоже, является Sax Parser) и удалите эту связь в вашем BuildConfig.groovy

Answer 3

SaxParseException загружается JVM, и я предполагаю, что плагин загружает более старую версию. Просто добавьте параметр исключений в плагин

Запустите grails «зависимость-отчет», чтобы узнать, какой jar-файл вызывает проблему.
