<p><code>pull-deps</code> is an Apache Druid tool that can pull down dependencies to the local repository and lay dependencies out into the extension directory as needed.</p>
<p><code>pull-deps</code> has several command line options, they are as follows:</p>
<p><code>-c</code> or <code>--coordinate</code> (Can be specified multiple times)</p>
<p>Extension coordinate to pull down, followed by a maven coordinate, e.g. org.apache.druid.extensions:mysql-metadata-storage</p>
<p><code>-h</code> or <code>--hadoop-coordinate</code> (Can be specified multiply times)</p>
<p>Apache Hadoop dependency to pull down, followed by a maven coordinate, e.g. org.apache.hadoop:hadoop-client:2.4.0</p>
<p><code>--no-default-hadoop</code></p>
<p>Don't pull down the default hadoop coordinate, i.e., org.apache.hadoop:hadoop-client:2.3.0. If <code>-h</code> option is supplied, then default hadoop coordinate will not be downloaded.</p>
<p><code>--clean</code></p>
<p>Remove existing extension and hadoop dependencies directories before pulling down dependencies.</p>
<p><code>-l</code> or <code>--localRepository</code></p>
<p>A local repository that Maven will use to put downloaded files. Then pull-deps will lay these files out into the extensions directory as needed.</p>
<p><code>-r</code> or <code>--remoteRepository</code></p>
<p>Add a remote repository. Unless <code>--no-default-remote-repositories</code> is provided, these will be used after <a href="https://repo1.maven.org/maven2/">https://repo1.maven.org/maven2/</a>.</p>
<p><code>--no-default-remote-repositories</code></p>
<p>Don't use the default remote repository, <a href="https://repo1.maven.org/maven2/">https://repo1.maven.org/maven2/</a>. Only use the repositories provided directly via --remoteRepository.</p>
<p><code>-d</code> or <code>--defaultVersion</code></p>
<p>Version to use for extension coordinate that doesn't have a version information. For example, if extension coordinate is <code>org.apache.druid.extensions:mysql-metadata-storage</code>, and default version is <code>26.0.0</code>, then this coordinate will be treated as <code>org.apache.druid.extensions:mysql-metadata-storage:26.0.0</code></p>
<p><code>--use-proxy</code></p>
<p>Use http/https proxy to send request to the remote repository servers. <code>--proxy-host</code> and <code>--proxy-port</code> must be set explicitly if this option is enabled.</p>
<p><code>--proxy-type</code></p>
<p>Set the proxy type, Should be either <em>http</em> or <em>https</em>, default value is <em>https</em>.</p>
<p><code>--proxy-host</code></p>
<p>Set the proxy host. e.g. proxy.com.</p>
<p><code>--proxy-port</code></p>
<p>Set the proxy port number. e.g. 8080.</p>
<p><code>--proxy-username</code></p>
<p>Set a username to connect to the proxy, this option is only required if the proxy server uses authentication.</p>
<p><code>--proxy-password</code></p>
<p>Set a password to connect to the proxy, this option is only required if the proxy server uses authentication.</p>
<p>To run <code>pull-deps</code>, you should</p>
<ol>
<li><p>Specify <code>druid.extensions.directory</code> and <code>druid.extensions.hadoopDependenciesDir</code>, these two properties tell <code>pull-deps</code> where to put extensions. If you don't specify them,  default values will be used, see <a href="/docs/26.0.0/configuration/index.html">Configuration</a>.</p></li>
<li><p>Tell <code>pull-deps</code> what to download using <code>-c</code> or <code>-h</code> option, which are followed by a maven coordinate.</p></li>
</ol>
<p>Example:</p>
<p>Suppose you want to download <code>mysql-metadata-storage</code> and <code>hadoop-client</code>(both 2.3.0 and 2.4.0) with a specific version, you can run <code>pull-deps</code> command with <code>-c org.apache.druid.extensions:mysql-metadata-storage:26.0.0</code>, <code>-h org.apache.hadoop:hadoop-client:2.3.0</code> and <code>-h org.apache.hadoop:hadoop-client:2.4.0</code>, an example command would be:</p>

</code></pre>
<p>Because <code>--clean</code> is supplied, this command will first remove the directories specified at <code>druid.extensions.directory</code> and <code>druid.extensions.hadoopDependenciesDir</code>, then recreate them and start downloading the extensions there. After finishing downloading, if you go to the extension directories you specified, you will see</p>
