Short answer: Your project is missing the logback-classic dependency:

<!-- https://mvnrepository.com/artifact/ch.qos.logback/logback-classic -->
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
    <scope>test</scope>
</dependency>

I guess you are not using any dependency management tool like Maven, Gradle or Ivy, that resolves transitive dependencies automatically. In your place I would look into those tools (it's probably best to start with Maven) instead of managing your dependencies yourself.
