How do you get a version from a maven project to create a docker tag on release?

Question

Maven

The maven-release-plugin maven.apache.org/maven-release/maven-release-plugin/ is used to automate release releases. This plugin modifies the source code in the git repository.

• remove 'SNAPSHOT' from ${project.version} root pom.xml and all modules (1.0.1-SNAPSHOT -> 1.0.1) and commit
  
• adding a tag to a commit with a fixed version (i.e. 1.0.1)
  
• commit the new SNAPSHOT version of pom.xml and all modules to the next SNAPSHOT (1.0.1 -> 1.0.2-SNAPSHOT)
  
• pushing changes to the Git server
  

How after the phase "adding a tag to a commit with a fixed version (i.e. to 1.0.1)" do the docker tag command?
