I have used Spring Initializr to create two modules:
api (which is Spring Web)
db (which is Spring Data MongoDB)
I have put them in the same project, in a way they are now submodules.
Before creating tests, I can mvn clean install
with a BUILD SUCCESS message. No problem there.
However, if I try to create a test (or even use it in a controller within main structure), where it uses a db module repository class, to get data from MongoDB, mvn clean install
will accuse package does not exist, despite IntelliJ can identify and index it and file exists.
Structure is:
api
- src/main/java
- com.example.api.controllers
- UserController.java
- src/test/java
- com.example.api.controllers
- UserControllerTest.java
db
- src/main/java
- com.example.db.repositories
- UserRepository.java
model
- src/main/java
- com.example.model
- User.java
UserControllerTest.java
package com.example.api.controllers;
import com.example.db.repositories.UserRepository;
import com.example.model.User;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import java.util.List;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class UserControllerTest {
@Autowired
private MockMvc mvc;
@Autowired
private UserRepository userRepository;
@Before
public void setUp() {
User user = new User();
userRepository.save(user);
}
@Test
public void getUser() throws Exception {
mvc.perform(MockMvcRequestBuilders.get("/v1/user").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk());
}
}
Now, if I run mvn clean install
, I shall receive maven error saying package com.example.db.repositories does not exist
.
Module db is a dependency in module api and api module is set to be compiled after db in parent's pom.

How to make maven see this package?
