Multiple tags for a Docker image built by Google Jib and Maven?

Using the jib-maven-plugin I'd like to build an image with mulitple tags. While mvn jib:build basically works fine, it "only" tags the image with latest.

My Maven pom.xml defines the following:

<plugin>
    <groupId>com.google.cloud.tools</groupId>
    <artifactId>jib-maven-plugin</artifactId>
    <version>2.8.0</version>
    <configuration>
        <to>
            <image>my-private-registry.org/my-image</image>
        </to>
    </configuration>
</plugin>

The docs show that one can use jib.to.tags in the XML to define a list of tags. However, I'd like to run the build step in a Jenkins pipeline, i.e. I cannot hard-code the tags in the pom.xml.

Is it possible to pass the list of tags when running the mvn command, e.g. by setting some -D parameters?

I was having the same question and I solved using this snippet in my pom.xml file:

<plugin>
    <groupId>com.google.cloud.tools</groupId>
    <artifactId>jib-maven-plugin</artifactId>
    <version>${jib-maven-plugin.version}</version>
    <configuration>
        <from>
            <image>${jib-maven-plugin.image}</image>
        </from>
        <to>
            <image>registry.gitlab.com/mygroup/myproject</image>
            <tags>
                <tag>latest</tag>
                <tag>${project.version}</tag>
            </tags>
        </to>
    </configuration>
</plugin>

simply calling mvn clean package -Pprod verify jib:build will push both latest and the project's version defined in pom
