  <p>Configuration:
  pom.xml </p>
  
  <pre><code>&lt;nexus.url&gt;http://adress/#browse/browse/components:docker-image&lt;/nexus.url&gt;
  
  &lt;distributionManagement&gt;
     &lt;snapshotRepository&gt;
          &lt;id&gt;nexus&lt;/id&gt;
          &lt;url&gt;${nexus.url}&lt;/url&gt;
      &lt;/snapshotRepository&gt;
  &lt;/distributionManagement&gt;
  ...
  &lt;plugins&gt;
          &lt;plugin&gt;
              &lt;groupId&gt;org.sonatype.plugins&lt;/groupId&gt;
              &lt;artifactId&gt;nexus-staging-maven-plugin&lt;/artifactId&gt;
              &lt;version&gt;1.6.4&lt;/version&gt;
              &lt;extensions&gt;true&lt;/extensions&gt;
              &lt;configuration&gt;
                &lt;serverId&gt;nexus&lt;/serverId&gt;
                &lt;nexusUrl&gt;${nexus.url}&lt;/nexusUrl&gt;
                &lt;autoReleaseAfterClose&gt;true&lt;/autoReleaseAfterClose&gt;
              &lt;/configuration&gt;
          &lt;/plugin&gt;
  </code></pre>
  
  <p>And i have file settings.xml:</p>
  
  <pre><code>&lt;servers&gt;
   &lt;server&gt;
      &lt;id&gt;nexus&lt;/id&gt;
      &lt;username&gt;login&lt;/username&gt;
      &lt;password&gt;password&lt;/password&gt;
   &lt;/server&gt;
  &lt;/servers&gt;
  </code></pre>
  
  <p>Then i try "mvn clean deploy" and result is:</p>
