Could not load TestContextBootstrapper [null]. Specify #BootstrapWith and dependency tree OK - spring

Question

I'm relatively new with Spring tests. I'm triying to test repositories.
After reading different posts about the same issue it seems to be a dependencies problem.
But I haven't found any conflict after checking it (see bellow).
This is the test class:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration
public class ActionRepositoryTest2 {
#Autowired ActionRepository actionRepository;
#Test
public void actionRepository() {
Command command = new Command();
Action action = new Action();
action.setText("TestAction");
actionRepository.save(action);
List<Action> actions = (List<Action>)
actionRepository.findAll();
assertNotNull(action);
assertEquals(actions.size(),1);
}
#Configuration
public static class InnerConf2 {
#Bean
ActionRepository actionRepository() {
return new ActionRepositoryImpl();
}
#Bean
CommandRepository commandRepository() {
return new CommandRepositoryImpl();
}
#Bean
OrderRepository orderRepository() {
return new OrderRepositoryImpl();
}
}
}
This is the exception I get:
ava.lang.IllegalStateException: Could not load TestContextBootstrapper [null]. Specify #BootstrapWith's 'value' attribute or make the default bootstrapper class available.
at org.springframework.test.context.BootstrapUtils.resolveTestContextBootstrapper(BootstrapUtils.java:144)
...
This is the dependency check:

Is there a way (the last option I consider) to trace SpringJUnit4ClassRunner?
Thanks.

Problem is with the maven dependency. Needs to keep the same spring-core and spring-test version which will solve the issue.
