Я следую за этой темой:Приложение JavaFx с Maven в Eclipse

И это туротиалhttps://www.youtube.com/watch?v=wbjW8rYlook

Я получаю
No plugin found for prefix 'jfx' in the current project and in the plugin groups
ошибка при попытке запустить цель:jfx:jar

Полная ошибка сборки:

Я уже попробовал следующее в попытке решить эту проблему:
1. Введитеmvn clean install (СТРОЙ УСПЕХ)
2. Добавлено<pluginGroup>com.zenjava</pluginGroup> на settings.xml

Кроме того, я уже добавил<plugin> узел в моем pom.xml

    <plugin>
        <groupId>com.zenjava</groupId>
        <artifactId>javafx-maven-plugin</artifactId>
        <version>8.1.2</version>
        <configuration>
            <mainClass>com.sample.MainApp</mainClass>
        </configuration>
    </plugin>

Как я могу решить эту проблему?

================================================== =========
ОБНОВЛЕНИЕ 1:
После ответа Jaydeep я получаю запрос пароля после попытки открыть файл cacerts и не могу продолжить.

================================================== =========
ОБНОВЛЕНИЕ 2:
Пароль по умолчанию для cacerts - "changeit".Сборка успешна после импорта корневого сертификата. Кроме того, я обновил мой pom-файл с помощью плагина jfx версии 8.7.0 в соответствии с рекомендациями FibreFoX.
