Not clear about how to set up credential for docker.io in maven

Description of the issue: Not able to build the docker image because of authentication.

Expected behavior: (1) credential should be picked up by the plugin and then it’s able to build the docker image which will be auto pushed to docker.io (2) how if I only want to build the docker image locally without auto push Steps to reproduce: mvn clean compile jib:build

Environment: Mac OS Apache Maven 3.5.4 jib-maven-plugin Configuration:

 <plugins>
      <plugin>
        <groupId>com.google.cloud.tools</groupId>
