Dependency injection on multi-Maven project with Spring and JavaFX

Question

Hi I'm working on a project with the following structure:

Healthcontrol (Maven parent project), with following children Maven modules:

-dbc (Spring JPA database)

-gui (JavaFX project, implemented as shown https://drogago.net/javafxmavenspring-step-by-step/)

-central (Module, supposed to be used for communication between modules), consisting of configs and services

The problem is, that we cannot inject anything from central module into GUI, error: No qualifying bean of type 'hc.module.gui.spring.configuration.Config' available. (injecting from dbc into central module is possible).

To make autowiring for dbc-central possible we use @Configuration 's :

'config dbc'
'config central'

and we tried to do the same for gui:

'config gui'

but it doesn't see any bean of used object.

Another problem is that pom.xml of gui don't see:

<dependency>
    <groupId>hc</groupId>
    <artifactId>central</artifactId>
    <version>1.0-SNAPSHOT</version>
    <scope>compile</scope>
</dependency>

All pom's looks like: ' parent pom ' ' dbc pom ' ' central pom ' ' gui pom '

How can we make it work?

Baeldung have a [trouble-shooting guide](https://www.baeldung.com/spring-nosuchbeandefinitionexception#cause-1) for the error `No Qualifying Bean of Type […] Found for Dependency`. — jewelsea, Jan 18 '22 at 21:12
Are you running `mvn install`? See this potential duplicate: [How to make one module depend on another module artifact?](https://stackoverflow.com/questions/4150180/how-to-make-one-module-depend-on-another-module-artifact) — jewelsea, Jan 18 '22 at 22:01
Ensure, that, after you run the install, you [reload all maven projects in Idea](https://www.jetbrains.com/help/idea/delegate-build-and-run-actions-to-maven.html#maven_reimport), "To reload all Maven projects, click the Reload All Maven Projects icon on the toolbar, in the Maven tool window." — jewelsea, Jan 18 '22 at 22:31
