Maven: Cannot find symbol (classes) from parent pom - spring-boot

I am not a maven expert and I am trying something new. I have created a framework which I want to use as parent project for all my microservices and which in turn containes all generic and abstract classes. I have declared packaging type pom in the framework pom:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

Then I created a microservice(another maven project), where I declared my framework as parent pom:

Unfortunately I'm gettin many 'cannot find symbol' at compile time... Why do I get these errors? Should not classes be found from parent pom?

Dependency managment in maven

Can someone explain me why my parent POM doesn't provide versions of dependecies for my child projects? I read 10 times docs on maven site and I'm stuck.
Here's my parent POM
<project xmlns="http://maven.apache.org/POM/4.0.0"

and one POM of my service

in this example version for API gateway isn't provide. In my opinion Hoxton.RELEASE should set the 2.2.1 version.
Another curious thing

Spring Boot (kotlin) circular dependency

I created the Spring Boot project with the Spring Boot Initializer. I have added Core, Data and Service modules. Now I see a warning after the build and in IntelliJ Project Structure: Project exampleapi: there is circular dependency between 'service' module, 'data' module, 'core' module.
Here is my pom:

And the pom of each module is the same except for artifactId:

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<version>0.0.1-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>service</artifactId>
<packaging>jar</packaging>
</project>

You get circular dependency error b/c each of the child modules inherits the parent's configuration where you declare dependencies on the childs. Hence the circular dependency error.
You need to remove parent reference from each of the childs for them not to inherit this dependency configuration.

That's actually pretty much the default you get when you create a spring-boot project with the starter tool.
What I would like to do is to create a jar of a package in this project in addition to the 'ueber-jar' this maven build already creates.
Let's say we have the following project structure:
src->main->java->com->test->me->myApp
This contains my complete code. In there is also a package named 'shared':
src->main->java->com->test->me->myApp->shared
Now everything in this 'shared' package should be compiled, packed into a JAR and copied to the 'target' folder.
How would I adjust my pom.xml to do this?

however, the project won't compile can not resolve the dependency of spring-boot-starter-parent and shows error in <version>1.3.8.RELEASE</version>
I have tried to reimport the pom dependencies and restart intellij. I can not find any imported library in my project structure since maven fails to resolve dependency
