Библиотека springfox-swagger2 ожидает, что вы сами предоставите зависимость jackson-databind, см. https://github.com/springfox/springfox/blob/2.7.0/gradle/dependencies.gradle строка 60-61.

Просто добавьте зависимость к jackson-databind: 

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.8.7</version>
</dependency>

2.8.7 также взято из dependencies.gradle springfox-swagger2.
