mock test failing while doing mvn install

I have below test which works successfully while executing in IDE but when I do mvn install it fails with below msg

org.mockito.exceptions.misusing.MissingMethodInvocationException: 
when() requires an argument which has to be 'a method call on a mock'.

Below is the test class:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = SpringockitoContextLoader.class,locations={"classpath:conf/test-context.xml"})

public class ServiceTest
{
    @ReplaceWithMock
    @Autowired
    private Object1 object1

    @Autowired
    private Service service;

    @Before
    public void setup()
    {
       MockitoAnnotations.initMocks(this);
    }   

    @Test
    public void test()
       {//below line is failing while doing mvn install
     Mockito.when(object1.validate(String validateMe)).thenReturn(true)
       }

}

Do I need any other extra configuration to have it work in maven ?
