from the parent root I generate all the modules using:

mvn clean package

But the problem is that the tdk-web-0.0.2-SNAPSHOT.jar does not contain the tdk-core-0.0.2-SNAPSHOT.jar and then it fails on the startup

Here the maven result:

This is the error I got:

***************************
APPLICATION FAILED TO START

Description:

Field emailService in com.tdkcloud.web.controllers.AppErrorController required a bean of type 'com.tdkcloud.backend.service.EmailService' that could not be found.


Action:

Consider defining a bean of type 'com.tdkcloud.backend.service.EmailService' in your configuration.

I unzipped the jar and there is no class of the core module

adding the proposed code to the module web:

                </plugin>

I have the next error: Error resolving template "/tdk/login/login", template might not exist or might not be accessible by any of the configured Template Reso

but the template is there: enter image description here

How do you create a multi-module project?

A multi-module project is built from an aggregator POM that manages a group of submodules. In most cases, the aggregator is located in the project's root directory and must have packaging of type pom. The submodules are regular Maven projects, and they can be built separately or through the aggregator POM.

I suggest this for creating a executable Jar.
