<h2 id="using-java-preview-features">Using Java preview features</h2>
<p>In order to analyze a project with PMD that uses preview language features, youll need to enable
it via the environment variable <code class="language-plaintext highlighter-rouge">PMD_JAVA_OPTS</code> and select the new language version, e.g. <code class="language-plaintext highlighter-rouge">19-preview</code>:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>export PMD_JAVA_OPTS=--enable-preview
./run.sh pmd -language java -version 19-preview ...
</code></pre></div></div>
<p>Note: we only support preview language features for the latest two java versions.</p>
