我正在尝试使用docker-maven-plugin（由spotify提供：https://github.com/spotify/docker-maven-plugin）使用Gitlab-CI构建一个docker镜像。
pom.xml
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>

<imageName>MY_REGISTRY/${project.artifactId}</imageName>

<registryUrl>https://MY_REGISTRY/v2/</registryUrl>
</configuration>

当我使用Jenkins时，我没有收到任何错误。
mvn clean javadoc:javadoc javadoc:test-javadoc deploy -Psonar sonar:sonar
在Gitlab-CI中，我将maven分为4个阶段：
部署阶段失败，我执行此命令：
mvn deploy
我不知道如何解决这个问题，我们将非常感谢任何意见。
