Почему Vaadin-Maven-плагин работает с несколькими версиями?

Question

У меня есть проект maven с vaadin 14.1.25 и Java EE 7, который создает файл .war. Когда я запускаю или собираю проект, я вижу, что идет другая версия vaadin-maven-pluging.

Such as in attached picture below:

 1. vaadin-maven-pluging: 14.1.17
 2. vaadin-maven-pluging: 14.1.19
 3. vaadin-maven-pluging: 15.0.0

В моем проекте только один плагин maven, который vaadin-maven-pluging: 14.1.25.

Может кто-нибудь объяснить, почему это происходит?
