In this guide, we will explain how to run and debug HugeGraph-Server on the Linux platform using <strong>IntelliJ IDEA</strong>.</p><p>The core steps for local startup are the same as starting with <strong>scripts</strong>:</p><ol><li>Initialize the database backend by executing the <code>InitStore</code> class to initialize the graph.</li><li>Start HugeGraph-Server by executing the <code>HugeGraphServer</code> class to load the initialized graph information and start the server.</li></ol><p>Before proceeding with the following process, make sure that you have cloned the source code of HugeGraph |
| and have configured the development environment, such as <code>Java 11</code> & you could config your local environment |
| with this <a href=https://github.com/apache/incubator-hugegraph/wiki/The-style-config-for-HugeGraph-in-IDEA>config-doc</a></p><div class=highlight><pre tabindex=0 style=background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4><code class=language-bash data-lang=bash><span style=display:flex><span>git clone https://github.com/apache/hugegraph.git |
| </span></span></code></pre></div><h3 id=steps>Steps</h3><h4 id=1-copy-configuration-files>1. Copy Configuration Files</h4><p>To avoid the impact of configuration file changes on Git tracking, it is recommended to copy the required configuration files to a separate folder. Run the following command to copy the files:</p><div class=highlight><pre tabindex=0 style=background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4><code class=language-bash data-lang=bash><span style=display:flex><span>cp -r hugegraph-dist/src/assembly/static/scripts hugegraph-dist/src/assembly/static/conf path-to-your-directory |
| </span></span></code></pre></div><p>Replace <code>path-to-your-directory</code> with the path to the directory where you want to copy the files.</p><h4 id=2-configure-initstore-to-initialize-the-graph>2. Configure <code>InitStore</code> to initialize the graph</h4><p>First, you need to configure the database backend in the configuration files. In this example, we will use RocksDB. Open <code>path-to-your-directory/conf/graphs/hugegraph.properties</code> and configure it as follows:</p><div class=highlight><pre tabindex=0 style=background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4><code class=language-fallback data-lang=fallback><span style=display:flex><span>backend=rocksdb |

| </span></span><span style=display:flex><span>rocksdb.data_path=. |
| </span></span><span style=display:flex><span>rocksdb.wal_path=. |
| </span></span></code></pre></div><p>Next, open the <code>Run/Debug Configurations</code> panel in IntelliJ IDEA and create a new Application configuration. Follow these steps for the configuration:</p><ul><li>Select <code>hugegraph-dist</code> as the <code>Use classpath of module</code>.</li><li>Set the <code>Main class</code> to <code>org.apache.hugegraph.cmd.InitStore</code>.</li><li>Set the program arguments to <code>conf/rest-server.properties</code>. Note that the path here is relative to the working directory, so make sure to set the working directory to <code>path-to-your-directory</code>.</li></ul><blockquote><p>If <strong>user authentication</strong> (authenticator) is configured for HugeGraph-Server in the <strong>Java 11</strong> environment, you need to refer to the script <a href=https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-dist/src/assembly/static/bin/init-store.sh#L52>configuration</a> in the binary package and add the following <strong>VM options</strong>:</p><div class=highlight><pre tabindex=0 style=background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4><code class=language-bash data-lang=bash><span style=display:flex><span>--add-exports<span style=color:#ce5c00;font-weight:700>=</span>java.base/jdk.internal.reflect<span style=color:#ce5c00;font-weight:700>=</span>ALL-UNNAMED |

Log4j2 Configuration</h4><p>By default, when running <code>InitStore</code> and <code>HugeGraphServer</code>, the Log4j2 configuration file path read is <code>hugegraph-dist/src/main/resources/log4j2.xml</code>, not <code>path-to-your-directory/conf/log4j2.xml</code>. This configuration file is read when starting HugeGraph-Server using the <strong>script</strong>.</p><p>To avoid maintaining two separate configuration files, you can modify the Log4j2 configuration file path when running and debugging HugeGraph-Server in <strong>IntelliJ IDEA</strong>:</p><ol><li>Open the previously created <code>Application</code> configuration.</li><li>Click on <code>Modify options</code> - <code>Add VM options</code>.</li><li>Set the VM options to <code>-Dlog4j.configurationFile=conf/log4j2.xml</code>.</li></ol><h3 id=possible-issues>Possible Issues</h3><h4 id=1-java-package-sunmisc-does-not-exist>1. java: package sun.misc does not exist</h4><p>The reason may be that cross-compilation is triggered when using Java 11 to compile, causing the symbol of <code>sun.misc.Unsafe</code> used in the project to not be found. There are two possible solutions:</p><ol><li>In IntelliJ IDEA, go to <code>Preferences/Settings</code> and find the <code>Java Compiler</code> panel. Then, disable the <code>--release</code> option (recommended).</li><li>Set the Project SDK to 8 (Deprecated soon).</li></ol><h4 id=2-java-storeraftrpcraftrequests-does-not-exist-rpc-generated-files>2. java: *.store.raft.rpc.RaftRequests does not exist (RPC Generated Files)</h4><p>The reason is that the source code didn’t include the <code>RPC-generated</code> files. You could try 2 ways to fix it:</p><ol><li>[CMD]<code>mvn clean compile</code> in the <strong>root</strong> directory (Recommend)</li><li>[UI] right click on the <code>hugegraph</code> repo and select <code>Maven->Generate Sources and Update Folders</code>. This will rebuild the repo and correctly generate the required files.</li></ol><h4 id=3-unable-to-print-location-information-l-in-log4j2>3. Unable to Print Location Information (%l) in Log4j2</h4><p>This is because Log4j2 uses asynchronous loggers. You can refer to the <a href=https://logging.apache.org/log4j/2.x/manual/layouts.html#LocationInformation>official documentation</a> for configuration details.</p><hr><h3
