We have a multi-module Spring boot project starting from scratch, the hierarchy is like this

The problem comes with the Controller in the account-service, the response bean and the error code of the API come from the common-service. Initially while importing it showed compilation issues for both but after doing a maven-update there were no errors.
This is the controller
package com.hh.sukku.account.controller;
import static com.hh.sukku.common.util.ErrorCodes.SUCCESS;
import javax.validation.Valid;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.hh.sukku.account.dto.UserDTO;
import com.hh.sukku.account.service.UserService;
import com.hh.sukku.common.beans.Response;
/**

*/
@RestController
@RequestMapping("v1/user")
public class UserController {
@Autowired
private UserService userService;
@PostMapping(path = "", consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Response> create(@Valid @RequestBody UserDTO request) {
userService.create(request);
Response response = new Response(SUCCESS, "Success");
return new ResponseEntity<Response>(response, HttpStatus.OK);
}
}
The problem starts when we try to do a maven clean install on the parent module, it fails with this error

[ERROR]
[ERROR] After correcting the problems, you can resume the build with the command
[ERROR] mvn <goals> -rf :account-service
We even tried maven clean install -X and maven install individually on the account-service. All attempts failed with the same error.
The fun fact is that the application can be started successfully but when we try to hit the API we are getting 404. What could be missing? There are no visible compilation errors.
The other interesting fact is that when we tried to import the controller from the account-service into the application-service and tried to build application-service it was a success. But when we tried to import a bean from the common-service the same got failed, so we can narrow down that the issue is with the common-service.
But at some point when we started the application-service we were able to process the request and insert data into the table, so we tried to build the parent pom, but again it failed. Later the application started giving 404 again for the same request.
Major changes with initial edit
groupId of the modules was not the same as the parent, so we created a new one with all of them having the same groupId. The issue remained the same.Response bean from the Fix project setup... option and locate the bean in the popup. The issue remained the same.Create a simple project (skip archetype selection) and Add project(s) to the working set, but the issue remained the same.pom from the profile section in the run configuration (reference), but the issue remained the same.compile package, which was successful, and two war files were generated application-service-1.0.0.war and hh-1.0.0.war. But the deployment was not fine, there were no logs of a spring boot application startup and requests were giving 404.Major changes with @Toerktumlare's suggestions
Removed the child modules from the .m2, and performed mvn clean package the result was the same failure.
Added the compiler plugin and performed step-1, failed again.
Tried running this command --projects account-service --also-make clean package for individual modules. First was common-service and it was successful, but with account-service it failed saying
[ERROR] Failed to execute goal on project account-service: Could not resolve dependencies for project com.hh.sukku:account-service:jar:1.0.0: Could not find artifact com.hh.sukku:common-service:jar:1.0.0 in central (https://repo.maven.apache.org/maven2)

After a test application was provided i managed to build the project after i applied what i recommended as a second course of action in the comments above which had not been implemented.
So by adding the following in the pom.xml i managed to compile the project
