<h2 id="30-july-2022---6480-snapshot">30-July-2022 - 6.48.0-SNAPSHOT</h2>
<p>The PMD team is pleased to announce PMD 6.48.0-SNAPSHOT.</p>
<p>This is a minor release.</p>
<h3 id="new-and-noteworthy">New and noteworthy</h3>
<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>
<h4 id="gherkin-support">Gherkin support</h4>
<p>Thanks to the contribution from <a href="https://github.com/ASBrouwers">Anne Brouwers</a> PMD now has CPD support
for the <a href="https://cucumber.io/docs/gherkin/">Gherkin</a> language. It is used to defined test cases for the
<a href="https://cucumber.io/">Cucumber</a> testing tool for behavior-driven development.</p>
<p>Being based on a proper Antlr grammar, CPD can:</p>
<ul>
<li>ignore comments</li>
<li>honor <a href="pmd_userdocs_cpd.html#suppression">comment-based suppressions</a></li>

<h3 id="api-changes">API Changes</h3>
<h4 id="rule-test-framework">Rule Test Framework</h4>
<ul>
<li>The module “pmd-test”, which contains support classes to write rule tests, now <strong>requires Java 8</strong>. If you depend on
this module for testing your own custom rules, you’ll need to make sure to use at least Java 8.</li>
<li>The new module “pmd-test-schema” contains now the XSD schema and the code to parse the rule test XML files. The
schema has been extracted in order to easily share it with other tools like the Rule Designer or IDE plugins.</li>
<li>Test schema changes:
<ul>
<li>The attribute <code class="language-plaintext highlighter-rouge">isRegressionTest</code> of <code class="language-plaintext highlighter-rouge">test-code</code> is deprecated. The new
attribute <code class="language-plaintext highlighter-rouge">disabled</code> should be used instead for defining whether a rule test should be skipped or not.</li>
<li>The attributes <code class="language-plaintext highlighter-rouge">reinitializeRule</code> and <code class="language-plaintext highlighter-rouge">useAuxClasspath</code> of <code class="language-plaintext highlighter-rouge">test-code</code> are deprecated and assumed true.
They will not be replaced.</li>
<li>The new attribute <code class="language-plaintext highlighter-rouge">focused</code> of <code class="language-plaintext highlighter-rouge">test-code</code> allows disabling all tests except the focused one temporarily.</li>
</ul>
</li>
<li>More information about the rule test framework can be found in the documentation:
<a href="pmd_userdocs_extending_testing.html">Testing your rules</a></li>
</ul>
<h4 id="deprecated-api">Deprecated API</h4>
<ul>
<li>The experimental Java AST class <a href="https://docs.pmd-code.org/apidocs/pmd-java/6.48.0-SNAPSHOT/net/sourceforge/pmd/lang/java/ast/ASTGuardedPattern.html#"><code>ASTGuardedPattern</code></a> has been deprecated and
will be removed. It was introduced for Java 17 and Java 18 Preview as part of pattern matching for switch,
but it is no longer supported with Java 19 Preview.</li>
<li>The interface <a href="https://docs.pmd-code.org/apidocs/pmd-core/6.48.0-SNAPSHOT/net/sourceforge/pmd/cpd/renderer/CPDRenderer.html#"><code>CPDRenderer</code></a> is deprecated. For custom CPD renderers
the new interface <a href="https://docs.pmd-code.org/apidocs/pmd-core/6.48.0-SNAPSHOT/net/sourceforge/pmd/cpd/renderer/CPDReportRenderer.html#"><code>CPDReportRenderer</code></a> should be used.</li>
<li>The class <a href="https://docs.pmd-code.org/apidocs/pmd-test/6.48.0-SNAPSHOT/net/sourceforge/pmd/testframework/TestDescriptor.html#"><code>TestDescriptor</code></a> is deprecated, replaced with <a href="https://docs.pmd-code.org/apidocs/pmd-test-schema/6.48.0-SNAPSHOT/net/sourceforge/pmd/testframework/RuleTestDescriptor.html#"><code>RuleTestDescriptor</code></a>.</li>
<li>Many methods of <a href="https://docs.pmd-code.org/apidocs/pmd-test/6.48.0-SNAPSHOT/net/sourceforge/pmd/testframework/RuleTst.html#"><code>RuleTst</code></a> have been deprecated as internal API.</li>
</ul>
<h4 id="experimental-apis">Experimental APIs</h4>
<ul>
<li>To support the Java preview language features “Pattern Matching for Switch” and “Record Patterns”, the following
AST nodes have been introduced as experimental:
<ul>
<li><a href="https://docs.pmd-code.org/apidocs/pmd-java/6.48.0-SNAPSHOT/net/sourceforge/pmd/lang/java/ast/ASTSwitchGuard.html#"><code>ASTSwitchGuard</code></a></li>
<li><a href="https://docs.pmd-code.org/apidocs/pmd-java/6.48.0-SNAPSHOT/net/sourceforge/pmd/lang/java/ast/ASTRecordPattern.html#"><code>ASTRecordPattern</code></a></li>
<li><a href="https://docs.pmd-code.org/apidocs/pmd-java/6.48.0-SNAPSHOT/net/sourceforge/pmd/lang/java/ast/ASTComponentPatternList.html#"><code>ASTComponentPatternList</code></a></li>
</ul>
</li>
</ul>
<h4 id="internal-api">Internal API</h4>
<p>Those APIs are not intended to be used by clients, and will be hidden or removed with PMD 7.0.0.
You can identify them with the <code class="language-plaintext highlighter-rouge">@InternalApi</code> annotation. You’ll also get a deprecation warning.</p>
