How to set up a maven multi-module project with the correct version and version structure

Question

I did not find the best practice for my multi-module maven project in terms of osgi versions, releases and packages,

First of all, this is Versioning and relase. my project has 5-6 auxiliary modules with 200 + jar, so we wanted to use aggregation,

Case 1: do not specify the project version and use the parent version

• in this case, if I use the maven release plugin and tagging, and pom.next ok for development (ok means jar3 will always use the latest version of jar1, which in itself), but what if I need to fix the patch only for jar1? how can I make relase (it says that the project cannot be released due to the not released dependent parent: 0.0.2-SNAPSHOT) and if I manage to release jar1 0.0.1.1, how can I tell jar3 to use the fixed version of jar1?

  Parent Project (0.0.1 Snapshot)
     Module1
    Jar1
    Jar2
     Module2
     Jar3
      (Dependencies) [Jar1 (project.version), Jar2 (project.version)]
    Jar4
      (Dependencies) [Jar1 (project.version), Jar3 (project.version) ]
  

2: , jar- pom

• , release , pom.next i ., jar, hardcoded (jar1.version), , 1- maven ,

  |   
    jar1.version
    jar2.version
    jar3.version
    jar4.version
     Module1
    Jar1 (jar1.version)
    Jar2 (jar2.version)
     Module2 (0.0.1-)
    Jar3 (jar3.version)
       () [Jar1, Jar2]
    Jar4 (0.0.1-)
       () [Jar1, Jar3]
