Wrong artifact name when building during a deploy phase

[dadoonet]

Description

• TL;DR: when using mvn deploy, docker plugin downloads the latest uploaded artifact from sonatype and does not use the finalName of the artifact.
• TL;DR: do not build your docker image within a deploy phase.

So let me try to explain the behavior.

I have a project where I'm building the docker image within the deploy phase. (Which is probably a bad idea).

<plugin>
    <groupId>io.fabric8</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>docker-build-push</id>
            <phase>deploy</phase>
            <goals>
                <goal>build</goal>
                <goal>push</goal>
            </goals>
        </execution>
    </executions>
</plugin>

I'm able to fix my build by splitting both phases (as shown below) but I think it's a bug that the behavior changes depending if you just have deployed or not the artifact before.

<plugin>
    <groupId>io.fabric8</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>docker-build</id>
            <phase>package</phase>
            <goals>
                <goal>build</goal>
            </goals>
        </execution>
        <execution>
            <id>docker-push</id>
            <phase>deploy</phase>
            <goals>
                <goal>push</goal>
            </goals>
        </execution>
    </executions>
</plugin>

What is funny in this story, is that the behavior changes if you call maven with -Dmaven.deploy.skip=true. In that case, the artifact is not uploaded to OSS Sonatype and then the local version is actually used instead of the remote one. So the docker build is correct. 😄

Hope this helps.

Thanks for reporting. I'll try to reproduce this and see if it's maven behavior or a bug in plugin itself. Do you have some sample reproducer project to try out?

@rohanKanojia Sadly not. But I could try to build one if you need it.
