Springboot 2 Could not initialize plugin: interface org.mockito.plugins.MockMaker

Question

Currently I test the new version of springboot 2. I created a @controller and the associated test by following the doc provided. But when I run the test, I always get the following exception:

2018-04-30 21:02:49.536  WARN 13584 --- [           main] o.s.test.context.TestContextManager      : Caught exception while invoking 'afterTestMethod' callback on TestExecutionListener [org.springframework.boot.test.mock.mockito.ResetMocksTestExecutionListener@1e81f160] for test method [public void com.example.demo.DemoApplicationTests.contextLoads()] and test instance [com.example.demo.DemoApplicationTests@1672fe87]

Here is the unit test :

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
public class DemoApplicationTests {

    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    public void contextLoads() {
    final String body = restTemplate.getForObject("/hello", String.class);
    assertThat(body).isEqualTo("Hello World");
    }
}

And here is my pom.xml

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>

        <relativePath /> <!-- lookup parent from repository -->

            <scope>test</scope>
        </dependency>
    </dependencies>
</project>

I followed the doc, but nothing to do the problem persists Who would have a solution?

Thank you
