Maven: Недействительный контент был найден, начиная с элемента 'plugin'

Я обновил pom.xml с помощью плагинов и получил ошибку:

 cvc-complex-type.2.4.a: Invalid content was found starting with element 'plugin'. One of      '{"http://maven.apache.org/POM/
 4.0.0":parent, "http://maven.apache.org/POM/4.0.0":description, "http://maven.apache.org/POM/4.0.0":prerequisites,
