使用Maven插件失败将Docker映像推送到Nexus

Question

我正在尝试使用maven插件将Docker映像推送到Nexus。 Docker映像是使用Spotify插件创建的

我的./m2/settings.xml文件中有

<servers>
  <server>
        <id>nexus</id>
        <username>usr</username>
        <password>pass</password>
    </server>
  </servers> 

我的pom.xml如下所示

...  
      <properties>
            <java.version>1.8</java.version>
            <docker.image.prefix>newems</docker.image.prefix>
            <nexus.url>http://urlnexus</nexus.url>
            <nexus.prefix>urlnexus</nexus.prefix>
        </properties>


    <distributionManagement>
        <snapshotRepository>
            <id>nexus</id>
            <url>${nexus.url}</url>
        </snapshotRepository>
    </distributionManagement>

     ....

执行mvn deploy命令时，出现以下错误消息

Uploading to nexus: http://urlnexus/xxxx/test-rest-service/0.0.1-SNAPSHOT/test-rest-service-0.0.1-20191128.115339-1-docker-info.jar

[ERROR] Failed to execute goal org.sonatype.plugins:nexus-staging-maven-plugin:1.6.4:deploy (injected-nexus-deploy) on project test-rest-service: Failed to deploy artifacts: Could not find artifact xxx:test-rest-service:jar:docker-info:0.0.1-20191128.115339-1 in nexus ( http://urlnexus/) -> [Help 1]

我看到它在罐子中添加了日期和时间，但是有什么原因吗？ 我在做什么错了？
