<h4 id="java-19-support">Java 19 Support</h4>
<p>This release of PMD brings support for Java 19. There are no new standard language features.</p>
<p>PMD supports <a href="https://openjdk.org/jeps/427">JEP 427: Pattern Matching for switch (Third Preview)</a> and
<a href="https://openjdk.org/jeps/405">JEP 405: Record Patterns (Preview)</a> as preview language features.</p>
<p>In order to analyze a project with PMD that uses these language features,
you’ll need to enable it via the environment variable <code class="language-plaintext highlighter-rouge">PMD_JAVA_OPTS</code> and select the new language
version <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: Support for Java 17 preview language features have been removed. The version “17-preview” is no longer available.</p>
