Answer 1

You need to change the scope of rest-assured in your pom file because according to your current configuration that dependency is only available during the test phase.

Try changing it to

<scope>compile</scope>

Answer 2

Changing my restassured dependency version from 3.0.0 to 3.0.7 solved the problem for me.

<dependency>
    <groupId>io.rest-assured</groupId>
    <artifactId>rest-assured</artifactId>
    <version>3.0.7</version>
    <scope>test</scope>
</dependency>
