Проект Maven не проходит тесты после удаления неиспользуемых зависимостей

Question

У меня есть проект maven, в котором я хочу уменьшить количество зависимостей с помощью файла pom.xml, который выглядит следующим образом:

<groupId>com.proj.itt</groupId>

После использования цели mvn dependency:analyze Iполучить в результате список неиспользованных объявленных зависимостей:

[WARNING] Unused declared dependencies found:
[WARNING]    org.apache.camel:camel-jetty:jar:2.23.1:compile
[WARNING]    org.apache.camel:camel-kafka:jar:2.23.1:compile
[WARNING]    org.apache.camel:camel-core:test-jar:tests:2.23.1:test
[WARNING]    org.springframework.kafka:spring-kafka:jar:2.2.0.RELEASE:compile
[WARNING]    org.springframework.kafka:spring-kafka-test:jar:2.2.0.RELEASE:compile

Но когда я пытаюсь удалить их, это приводит к сбоям в моем проекте.Почему это происходит?Проверяет ли также maven зависимости, связанные с тестами?
