NoSuchMethodError: org.mockito.internal.runners.RunnerFactory.createStrict

Question

I am using latest versions of JUnitParams, junit and mockito-all.

testCompile group: 'pl.pragmatists', name: 'JUnitParams', version: '1.1.1'
testCompile group: 'junit', name: 'junit', version: '4.12'
testCompile group: 'org.mockito', name: 'mockito-all', version: '2.0.2-beta'

I keep getting NoSuchMethodError when running a JUnit test with annotation @RunWith(MockitoJUnitRunner.class).

java.lang.NoSuchMethodError: org.mockito.internal.runners.RunnerFactory.createStrict(Ljava/lang/Class;)Lorg/mockito/internal/runners/InternalRunner;

What can be the problem that triggers NoSuchMethodError exception?

Code:

@RunWith(MockitoJUnitRunner.class)
public class MockTest {

    @Mock
    ServletUriComponentsBuilder servletUriComponentsBuilder;

    @Before
    public void setup() {
        servletUriComponentsBuilder = mock(ServletUriComponentsBuilder.class);
    }

    @Test
    public void shouldGenerateUrl() {
        when(servletUriComponentsBuilder.fromUriString(anyString()).build().toString())
                .thenReturn("test");

        Assert.assertEquals("my message", "test", "test");
    }

}

mockito-core

You have Mockito 1.x and 2.x on your classpath. I think that is because you have a dependency to mockito-all:2.0.2-beta and some of your other dependencies has a transitive dependency to mockito-core:1.x.

You should never use mockito-all with a build system that does your dependency management. Instead use

testCompile group: 'org.mockito', name: 'mockito-core', version: '2.0.2-beta'

or even a more current version (see The Central Repository)

Mockito documentation: https://github.com/mockito/mockito/wiki/Declaring-mockito-dependency

Please tell me, if this does not solve the problem.

Creation of mocks

This is not the cause of your problem but maybe helpful, too. You are creating the ServletUriComponentsBuilder twice. First the MockitoRunner creates it because of the @Mock annotation and then you override it with a new mock in you setup method. So either you do

@RunWith(MockitoJUnitRunner.class)
public class MockTest {

    @Mock
    ServletUriComponentsBuilder servletUriComponentsBuilder;

    @Test
    ...

or you do

public class MockTest {

    ServletUriComponentsBuilder servletUriComponentsBuilder;

    @Before
    public void setup() {
        servletUriComponentsBuilder = mock(ServletUriComponentsBuilder.class);
    }

    @Test
    ...

You may even do this shorter

public class MockTest {

    ServletUriComponentsBuilder servletUriComponentsBuilder
         = mock(ServletUriComponentsBuilder.class);

    @Test
    ...
