<h2 id="--2023---700-snapshot">??-?????-2023 - 7.0.0-SNAPSHOT</h2>
<p>We’re excited to bring you the next major version of PMD!</p>
<p>Since this is a big release, we provide here only a concise version of the release notes. We prepared a separate
page with the full <a href="pmd_release_notes_pmd7.html">Detailed Release Notes for PMD 7.0.0</a>.</p>
<div style="border: 1px solid; border-radius: .25rem; padding: .75rem 1.25rem;" role="alert">
<strong>ℹ️ Release Candidates</strong>
<p>PMD 7.0.0 is finally almost ready. In order to gather feedback, we are going to ship a couple of release candidates.
These are officially available on GitHub and Maven Central and can be used as usual (e.g. as a dependency).
We encourage you to try out the new features, but keep in mind that we may introduce API breaking changes between
the release candidates. It should be stable enough if you don't use custom rules.</p>
<p>We have still some tasks planned for the next release candidates.
You can see the progress in <a href="https://github.com/pmd/pmd/issues/3898">PMD 7 Tracking Issue #3898</a>.</p>
<p>If you find any problem or difficulty while updating from PMD 6, please provide feedback via our
<a href="https://github.com/pmd/pmd/issues/new/choose">issue tracker</a>. That way we can improve the experience
for all.</p>
</div>
<h3 id="changes-since-700-rc4">Changes since 7.0.0-rc4</h3>
<p>This section lists the most important changes from the last release candidate.
The remaining section describes the complete release notes for 7.0.0.</p>
<h4 id="new-and-noteworthy">New and Noteworthy</h4>
<h5 id="maven-pmd-plugin-compatibility-with-pmd-7">Maven PMD Plugin compatibility with PMD 7</h5>
<p>In order to use PMD 7 with <a href="https://maven.apache.org/plugins/maven-pmd-plugin/">maven-pmd-plugin</a> a new
compatibility module has been created. This allows to use PMD 7 by simply adding one additional dependency:</p>
<ol>
<li>Follow the guide <a href="https://maven.apache.org/plugins/maven-pmd-plugin/examples/upgrading-PMD-at-runtime.html">Upgrading PMD at Runtime</a></li>
<li>Add additionally the following dependency:</li>
</ol>
<div class="language-xml highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nt">&lt;dependency&gt;</span>
<span class="nt">&lt;groupId&gt;</span>net.sourceforge.pmd<span class="nt">&lt;/groupId&gt;</span>
<span class="nt">&lt;artifactId&gt;</span>pmd-compat6<span class="nt">&lt;/artifactId&gt;</span>
<span class="nt">&lt;version&gt;</span>${pmdVersion}<span class="nt">&lt;/version&gt;</span>
<span class="nt">&lt;/dependency&gt;</span>
</code></pre></div></div>
<p>It is important to add this dependency as the <strong>first</strong> in the list, so that maven-pmd-plugin sees the (old)
compatible versions of some classes.</p>
<p>This module is available beginning with version 7.0.0-rc4 and will be there at least for the first
final version PMD 7 (7.0.0). It’s not decided yet, whether we will keep updating it, after PMD 7 is finally
released.</p>
<p>Note: This compatibility module only works for the built-in rules, that are still available in PMD 7. E.g. you need
to review your rulesets and look out for deprecated rules and such. See the use case
<a href="pmd_userdocs_migrating_to_pmd7.html#im-using-only-built-in-rules">I’m using only built-in rules</a>
in the <a href="pmd_userdocs_migrating_to_pmd7.html">Migration Guide for PMD 7</a>.</p>
<p>As PMD 7 revamped the Java module, if you have custom rules, you need to migrate these rules.
See the use case <a href="pmd_userdocs_migrating_to_pmd7.html#im-using-custom-rules">I’m using custom rules</a>
in the Migration Guide.</p>

<p><strong>Removed classes and methods</strong></p>
<p>The following previously deprecated classes have been removed:</p>

<ul>
<li>
<p><code class="language-plaintext highlighter-rouge">#getApexVersion()</code>: In PMD 6, this method has been deprecated but was defined in the class <code class="language-plaintext highlighter-rouge">ApexRootNode</code>.
The version returned is always “Version.CURRENT”, as the apex compiler integration
doesn’t use additional information which Apex version actually is used. Therefore, this method can’t be
used to determine the Apex version of the project that is being analyzed.</p>
<p>If the current version is needed, then <code class="language-plaintext highlighter-rouge">Node.getTextDocument().getLanguageVersion()</code> can be used. This
is the version that has been selected via CLI <code class="language-plaintext highlighter-rouge">--use-version</code> parameter.</p>

<h4 id="new-java-21-support">New: Java 21 Support</h4>
<p>This release of PMD brings support for Java 21. There are the following new standard language features,
that are supported now:</p>
<ul>
<li><a href="https://openjdk.org/jeps/440">JEP 440: Record Patterns</a></li>
<li><a href="https://openjdk.org/jeps/441">JEP 441: Pattern Matching for switch</a></li>
</ul>
<p>PMD also supports the following preview language features:</p>
<ul>
<li><a href="https://openjdk.org/jeps/430">JEP 430: String Templates (Preview)</a></li>
<li><a href="https://openjdk.org/jeps/443">JEP 443: Unnamed Patterns and Variables (Preview)</a></li>
<li><a href="https://openjdk.org/jeps/445">JEP 445: Unnamed Classes and Instance Main Methods (Preview)</a></li>
</ul>
<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">21-preview</code>:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>export PMD_JAVA_OPTS=--enable-preview
pmd check --use-version java-21-preview ...
</code></pre></div></div>
<p>Note: Support for Java 19 preview language features have been removed. The version “19-preview” is no longer available.</p>

<ul>
<li>All statistical rules (like ExcessiveClassLength, ExcessiveParameterList) have been simplified and unified.
The properties <code class="language-plaintext highlighter-rouge">topscore</code> and <code class="language-plaintext highlighter-rouge">sigma</code> have been removed. The property <code class="language-plaintext highlighter-rouge">minimum</code> is still there, however the type is not
a decimal number anymore but has been changed to an integer. This affects rules in the languages Apex, Java, PLSQL
and Velocity Template Language (vm):

<li>The general property <code class="language-plaintext highlighter-rouge">violationSuppressXPath</code> which is available for all rules to
<a href="pmd_userdocs_suppressing_warnings.html">suppress warnings</a> now uses XPath version 3.1 by default.
This version of the XPath language is mostly identical to XPath 2.0. In PMD 6, XPath 1.0 has been used.

<li>The properties <code class="language-plaintext highlighter-rouge">cc_categories</code>, <code class="language-plaintext highlighter-rouge">cc_remediation_points_multiplier</code>, <code class="language-plaintext highlighter-rouge">cc_block_highlighting</code> have been removed
from all rules. These properties have been deprecated since PMD 6.13.0.
See <a href="https://github.com/pmd/pmd/issues/1648">issue #1648</a> for more details.</li>
</ul>
<p><strong>Java General changes</strong></p>
<ul>
<li>
<p>Violations reported on methods or classes previously reported the line range of the entire method
or class. With PMD 7.0.0, the reported location is now just the identifier of the method or class.
This affects various rules, e.g. <a href="pmd_rules_java_design.html#cognitivecomplexity"><code class="language-plaintext highlighter-rouge">CognitiveComplexity</code></a>.</p>
<p>The report location is controlled by the overrides of the method <a href="https://docs.pmd-code.org/apidocs/pmd-core/7.0.0-SNAPSHOT/net/sourceforge/pmd/lang/ast/Node.html#getReportLocation()"><code>getReportLocation</code></a>
in different node types.</p>
<p>See <a href="https://github.com/pmd/pmd/issues/4439">issue #4439</a> and <a href="https://github.com/pmd/pmd/issues/730">issue #730</a>
for more details.</p>
</li>
</ul>
<p><strong>Java Best Practices</strong></p>
<ul>
<li><a href="pmd_rules_java_bestpractices.html#arrayisstoreddirectly"><code class="language-plaintext highlighter-rouge">ArrayIsStoredDirectly</code></a>: Violations are now reported on the assignment and not
anymore on the formal parameter. The reported line numbers will probably move.</li>
<li><a href="pmd_rules_java_bestpractices.html#avoidreassigningloopvariables"><code class="language-plaintext highlighter-rouge">AvoidReassigningLoopVariables</code></a>: This rule might not report anymore all
reassignments of the control variable in for-loops when the property <code class="language-plaintext highlighter-rouge">forReassign</code> is set to <code class="language-plaintext highlighter-rouge">skip</code>.
See <a href="https://github.com/pmd/pmd/issues/4500">issue #4500</a> for more details.</li>
<li><a href="pmd_rules_java_bestpractices.html#loosecoupling"><code class="language-plaintext highlighter-rouge">LooseCoupling</code></a>: The rule has a new property to allow some types to be coupled
to (<code class="language-plaintext highlighter-rouge">allowedTypes</code>).</li>
<li><a href="pmd_rules_java_bestpractices.html#unusedlocalvariable"><code class="language-plaintext highlighter-rouge">UnusedLocalVariable</code></a>: This rule has some important false-negatives fixed
and finds many more cases now. For details see issues <a href="https://github.com/pmd/pmd/issues/2130">#2130</a>,
<a href="https://github.com/pmd/pmd/issues/4516">#4516</a>, and <a href="https://github.com/pmd/pmd/issues/4517">#4517</a>.</li>
</ul>
<p><strong>Java Codestyle</strong></p>
<ul>
<li><a href="pmd_rules_java_codestyle.html#methodnamingconventions"><code class="language-plaintext highlighter-rouge">MethodNamingConventions</code></a>: The property <code class="language-plaintext highlighter-rouge">checkNativeMethods</code> has been removed. The
property was deprecated since PMD 6.3.0. Use the property <code class="language-plaintext highlighter-rouge">nativePattern</code> to control whether native methods
should be considered or not.</li>
<li><a href="pmd_rules_java_codestyle.html#shortvariable"><code class="language-plaintext highlighter-rouge">ShortVariable</code></a>: This rule now also reports short enum constant names.</li>
<li><a href="pmd_rules_java_codestyle.html#usediamondoperator"><code class="language-plaintext highlighter-rouge">UseDiamondOperator</code></a>: The property <code class="language-plaintext highlighter-rouge">java7Compatibility</code> has been removed. The rule now
handles Java 7 properly without a property.</li>
<li><a href="pmd_rules_java_codestyle.html#unnecessaryfullyqualifiedname"><code class="language-plaintext highlighter-rouge">UnnecessaryFullyQualifiedName</code></a>: The rule has two new properties,
to selectively disable reporting on static field and method qualifiers. The rule also has been improved
to be more precise.</li>
<li><a href="pmd_rules_java_codestyle.html#uselessparentheses"><code class="language-plaintext highlighter-rouge">UselessParentheses</code></a>: The rule has two new properties which control how strict
the rule should be applied. With <code class="language-plaintext highlighter-rouge">ignoreClarifying</code> (default: true) parentheses that are strictly speaking
not necessary are allowed, if they separate expressions of different precedence.
The other property <code class="language-plaintext highlighter-rouge">ignoreBalancing</code> (default: true) is similar, in that it allows parentheses that help
reading and understanding the expressions.</li>
<li><a href="pmd_rules_java_codestyle.html#emptycontrolstatement"><code class="language-plaintext highlighter-rouge">EmptyControlStatement</code></a>: The rule has a new property to allow empty blocks when
they contain a comment (<code class="language-plaintext highlighter-rouge">allowCommentedBlocks</code>).</li>
</ul>
<p><strong>Java Design</strong></p>
<ul>
<li><a href="pmd_rules_java_design.html#cyclomaticcomplexity"><code class="language-plaintext highlighter-rouge">CyclomaticComplexity</code></a>: The property <code class="language-plaintext highlighter-rouge">reportLevel</code> has been removed. The property was
deprecated since PMD 6.0.0. The report level can now be configured separated for classes and methods using
<code class="language-plaintext highlighter-rouge">classReportLevel</code> and <code class="language-plaintext highlighter-rouge">methodReportLevel</code> instead.</li>
<li><a href="pmd_rules_java_design.html#immutablefield"><code class="language-plaintext highlighter-rouge">ImmutableField</code></a>: The property <code class="language-plaintext highlighter-rouge">ignoredAnnotations</code> has been removed. The property was
deprecated since PMD 6.52.0.</li>
<li><a href="pmd_rules_java_design.html#lawofdemeter"><code class="language-plaintext highlighter-rouge">LawOfDemeter</code></a>: The rule has a new property <code class="language-plaintext highlighter-rouge">trustRadius</code>. This defines the maximum degree
of trusted data. The default of 1 is the most restrictive.</li>
<li><a href="pmd_rules_java_design.html#npathcomplexity"><code class="language-plaintext highlighter-rouge">NPathComplexity</code></a>: The property <code class="language-plaintext highlighter-rouge">minimum</code> has been removed. It was deprecated since PMD 6.0.0.
Use the property <code class="language-plaintext highlighter-rouge">reportLevel</code> instead.</li>
<li><a href="pmd_rules_java_design.html#singularfield"><code class="language-plaintext highlighter-rouge">SingularField</code></a>: The properties <code class="language-plaintext highlighter-rouge">checkInnerClasses</code> and <code class="language-plaintext highlighter-rouge">disallowNotAssignment</code> have been removed.
The rule is now more precise and will check these cases properly.</li>
<li><a href="pmd_rules_java_design.html#useutilityclass"><code class="language-plaintext highlighter-rouge">UseUtilityClass</code></a>: The property <code class="language-plaintext highlighter-rouge">ignoredAnnotations</code> has been removed.</li>
</ul>
<p><strong>Java Documentation</strong></p>
<ul>
<li><a href="pmd_rules_java_documentation.html#commentcontent"><code class="language-plaintext highlighter-rouge">CommentContent</code></a>: The properties <code class="language-plaintext highlighter-rouge">caseSensitive</code> and <code class="language-plaintext highlighter-rouge">disallowedTerms</code> are removed. The
new property <code class="language-plaintext highlighter-rouge">forbiddenRegex</code> can be used now to define the disallowed terms with a single regular
expression.</li>
<li><a href="pmd_rules_java_documentation.html#commentrequired"><code class="language-plaintext highlighter-rouge">CommentRequired</code></a>:
<ul>
<li>Overridden methods are now detected even without the <code class="language-plaintext highlighter-rouge">@Override</code>
annotation. This is relevant for the property <code class="language-plaintext highlighter-rouge">methodWithOverrideCommentRequirement</code>.
See also <a href="https://github.com/pmd/pmd/pull/3757">pull request #3757</a>.</li>
<li>Elements in annotation types are now detected as well. This might lead to an increased number of violations
for missing public method comments.</li>
</ul>
</li>
<li><a href="pmd_rules_java_documentation.html#commentsize"><code class="language-plaintext highlighter-rouge">CommentSize</code></a>: When determining the line-length of a comment, the leading comment
prefix markers (e.g. <code class="language-plaintext highlighter-rouge">*</code> or <code class="language-plaintext highlighter-rouge">//</code>) are ignored and don’t add up to the line-length.
See also <a href="https://github.com/pmd/pmd/pull/4369">pull request #4369</a>.</li>
</ul>
<p><strong>Java Error Prone</strong></p>
<ul>
<li><a href="pmd_rules_java_errorprone.html#avoidduplicateliterals"><code class="language-plaintext highlighter-rouge">AvoidDuplicateLiterals</code></a>: The property <code class="language-plaintext highlighter-rouge">exceptionfile</code> has been removed. The property was
deprecated since PMD 6.10.0. Use the property <code class="language-plaintext highlighter-rouge">exceptionList</code> instead.</li>
<li><a href="pmd_rules_java_errorprone.html#dontimportsun"><code class="language-plaintext highlighter-rouge">DontImportSun</code></a>: <code class="language-plaintext highlighter-rouge">sun.misc.Signal</code> is not special-cased anymore.</li>
<li><a href="pmd_rules_java_errorprone.html#emptycatchblock"><code class="language-plaintext highlighter-rouge">EmptyCatchBlock</code></a>: <code class="language-plaintext highlighter-rouge">CloneNotSupportedException</code> and <code class="language-plaintext highlighter-rouge">InterruptedException</code> are not
special-cased anymore. Rename the exception parameter to <code class="language-plaintext highlighter-rouge">ignored</code> to ignore them.</li>
<li><a href="pmd_rules_java_errorprone.html#implicitswitchfallthrough"><code class="language-plaintext highlighter-rouge">ImplicitSwitchFallThrough</code></a>: Violations are now reported on the case statements
rather than on the switch statements. This is more accurate but might result in more violations now.</li>
</ul>
<h4 id="removed-rules">Removed Rules</h4>
<p>Many rules, that were previously deprecated have been finally removed.
See <a href="pmd_release_notes_pmd7.html">Detailed Release Notes for PMD 7</a> for the complete list.</p>
<h3 id="-api">🚨 API</h3>
<p>The API of PMD has been growing over the years and needed some cleanup. The goal is, to
have a clear separation between a well-defined API and the implementation, which is internal.
This should help us in future development.</p>
<p>Also, there are some improvement and changes in different areas. For the detailed description
of the changes listed here, see <a href="pmd_release_notes_pmd7.html">Detailed Release Notes for PMD 7</a>.</p>
<ul>
<li>Miscellaneous smaller changes and cleanups</li>
<li>XPath 3.1 support for XPath-based rules</li>
<li>Node stream API for AST traversal</li>
<li>Metrics framework</li>
<li>Testing framework</li>
<li>Language Lifecycle and Language Properties</li>
<li>Rule Properties</li>
<li>New Programmatic API for CPD</li>
</ul>
