maven pom to gradle — сбой плагина сборки

В настоящее время у меня есть проекты JAVA Maven, и я пытаюсь перенести их в Gradle. Я выпустил следующую команду, чтобы преобразовать ее,

gradle init

Пожалуйста, найдите pom.xml, XML-файл дескриптора моего проекта и сгенерированные файлы build.gradle ниже,
