Maven Repository on Github?

Question

Java

Can't create Maven Repository on Github.
1) I created a repository in github https://github.com/alikdemon1/phonebook
2) Set up pom.xml

</project>

3) Created .m2/settings.xml

<settings>
  <servers>
    <server>
      <id>github</id>
      <username>[username]</username>
      <password>[password]</password>
    </server>
  </servers>
</settings>

4) Made mvn clean deploy
5) Displays such an error

What could be the problem?

Answer 1

invalid request.
Googled a couple of similar issues:
https://github.com/github/maven-plugins/issues/69
The thread is long, there is a lot going on, in general, I would read it here.

Answer 2
