Looks like you are missing the below dependency

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-api</artifactId>
    <version>3.0.1</version>
</dependency>

Since you have not shared your pom file, its difficult to say what is causing this above mentioned artifact to get excluded.
