<h2 id="introduction">Introduction</h2>
<p>When you are familiar with building and testing the JDK, you may want to configure an IDE to work with the source code. The instructions differ a bit depending on whether you are interested in working with the native (C/C++) or the Java code.</p>
<h3 id="ide-support-for-native-code">IDE support for native code</h3>
<p>There are a few ways to generate IDE configuration for the native sources, depending on which IDE to use.</p>
<h4 id="visual-studio-code">Visual Studio Code</h4>
<p>The make system can generate a <a href="https://code.visualstudio.com">Visual Studio Code</a> workspace that has C/C++ source indexing configured correctly, as well as launcher targets for tests and the Java launcher. After configuring, a workspace for the configuration can be generated using:</p>
<pre class="shell"><code>make vscode-project</code></pre>
<p>This creates a file called <code>jdk.code-workspace</code> in the build output folder. The full location will be printed after the workspace has been generated. To use it, choose <code>File -&gt; Open Workspace...</code> in Visual Studio Code.</p>
<h5 id="alternative-indexers">Alternative indexers</h5>
<p>The main <code>vscode-project</code> target configures the default C++ support in Visual Studio Code. There are also other source indexers that can be installed, that may provide additional features. It's currently possible to generate configuration for two such indexers, <a href="https://clang.llvm.org/extra/clangd/">clangd</a> and <a href="https://github.com/Andersbakken/rtags">rtags</a>. These can be configured by appending the name of the indexer to the make target, such as:</p>
<pre class="shell"><code>make vscode-project-clangd</code></pre>
<p>Additional instructions for configuring the given indexer will be displayed after the workspace has been generated.</p>
<h4 id="visual-studio">Visual Studio</h4>
<p>This section is a work in progress.</p>
<pre class="shell"><code>make ide-project</code></pre>
<h4 id="compilation-database">Compilation Database</h4>
<p>The make system can generate generic native code indexing support in the form of a <a href="https://clang.llvm.org/docs/JSONCompilationDatabase.html">Compilation Database</a> that can be used by many different IDEs and source code indexers.</p>
<pre class="shell"><code>make compile-commands</code></pre>
<p>It's also possible to generate the Compilation Database for the HotSpot source code only, which is a bit faster as it includes less information.</p>
<pre class="shell"><code>make compile-commands-hotspot</code></pre>
