Why is my import of the containsString method not working?

I thought I had tried every worthwhile import statement already, but this one did the trick:

import static org.junit.matchers.JUnitMatchers.*;

I faced the same issue with a Spring Boot app. Seems like this is a dependency ordering issue.. one of the dependencies mentioned in pom.xml before the "spring-boot-starter-test" artifact was overriding the hamcrest version.

So all I did was change the order (moved this dependency up):

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>

I'm using Spring Boot 1.5.7.RELEASE.
