pom dependancy between different projects maven

Question

I have a project structure as follows:

I would like to put in common modules and classes visible to all microservices so I thought of adding common as a dependancy to microsevices but I get:

[INFO] gamification ....................................... SUCCESS [  4.178 s]
[INFO] multiplication ..................................... SUCCESS [  2.089 s]
[INFO] microservices ...................................... FAILURE [  0.069 s]
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Total time:  6.694 s
[INFO] Finished at: 2022-12-01T23:52:34+01:00
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal on project microservices-parent: Could not resolve dependencies for project org.springframework.boot:microservices-parent:pom:0.0.1-SNAPSH
OT: Could not find artifact com.microservices.book:common-parent:jar:0.0.1-SNAPSHOT

After some diggin around I found that I can't link these two projects like that (so), and that I should probably use local repository... but I have no idea how. I don't even know how to save maven builds to the .m2 folder, I've tried:

 mvn -Dmaven.repo.local=C:\Users\pengwin\.m2\repository clean install

but I get:

[ERROR] No plugin found for prefix '.repo.local=C' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repos
itories [local (C:\Users\pengwin\.m2\repository), central (https://repo.maven.apache.org/maven2)] -> [Help 1]

Here's microservices's pom.xml:
