ReflectionUtil error in Component/Functional Test with Repository layer - spring

Question

I am trying to run a JUnit test on my Repository layer
#ExtendWith(SpringExtension.class)
#SpringBootTest(classes = {JPAConfig.class, SpringBootMainApplication.class})
public class AddBookTest {
#Autowired
private BookRepository bookRepository;
#Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
#BeforeEach
public void setUp() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
}
#Test
#Sql({"/book-schema.sql", "/book-data.sql"})
void addBook() throws Exception {
mockMvc.perform(MockMvcRequestBuilders.put("/users/")
.header("X-MC-CorrelationID", UUID.randomUUID())
.contentType(MediaType.APPLICATION_JSON_VALUE)
.accept(MediaType.APPLICATION_JSON)
.characterEncoding("UTF-8")
.content("{\"book\": \"LOTR\"}")
.andExpect(MockMvcResultMatchers.status().isNoContent())
.andDo(MockMvcResultHandlers.print());
}
private String requestBody() {
return "{\n" +
" \"book\": \"LOTR\",\n" +
"}";
}
}
I am getting the following error:
java.lang.NoSuchMethodError: 'org.springframework.util.ReflectionUtils$MethodFilter org.springframework.util.ReflectionUtils$MethodFilter.and(org.springframework.util.ReflectionUtils$MethodFilter)'

Version:

testImplementation group: 'org.springframework', name: 'spring-test', version: "5.2.1.RELEASE"
implementation group: 'org.springframework', name: 'spring-context', version: "5.2.1.RELEASE"
In short, all my Spring Boot dependencies are on 2.2.1.RELEASE train while the Spring framework is 5.2.1.RELEASE. Are these versions compatible?

Answer 1

Its hard to say for sure what happens but is sounds like a clash of versions of spring that you have on your classpath.
This specific method "and" is pretty new see the javadoc. It explicitly states that the method is since version "5.3.2" which is pretty new.
So I suggest examining the dependency tree of jars in the test class path to understand whether you mix between a new and some older versions of Spring.
