Unresolvable parent POM in Jira Rest Java Client

[Godsim]

Hi everyone,

I need to write an application, that connects to the REST API of our Jira instance and   
since I can't find any ready-to-go jar of the jira-rest-java-client from Atlassian Bitbucket I wanted to create it myself by cloning it and adding the Atlassian Maven Repo Proxy to my  settings.xml as suggested at Developer.Atlassian.

Unfortunately I still can not package the API client, since the dependency of the parent POM
remains unresolvable.

<parent>
    <groupId>com.atlassian.pom</groupId>
    <artifactId>public-pom</artifactId>
    <version>5.0.8</version>
</parent>

 This problem might be recurring since it was already reported in 2019 here Atlassian Community

Any help would be highly appreciated!
