<div class="summary">A ruleset is an XML configuration file, which describes a collection of rules to be executed in a PMD run. PMD includes built-in rulesets to run quick analyses with a default configuration, but users are encouraged to make their own rulesets from the start, because they allow for so much configurability. This page walk you through the creation of a ruleset and the multiple configuration features offered by rulesets.</div>

<h2 id="creating-a-ruleset">Creating a ruleset</h2>
|
||
|
||
<p>The first step is to create a new empty ruleset. You can use the following template:</p>
|
||
|
||
<div class="language-xml highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="cp"><?xml version="1.0"?></span>
|
||
|
||
<span class="nt"><ruleset</span> <span class="na">name=</span><span class="s">"Custom Rules"</span>
|
||
<span class="na">xmlns=</span><span class="s">"http://pmd.sourceforge.net/ruleset/2.0.0"</span>
|
||
<span class="na">xmlns:xsi=</span><span class="s">"http://www.w3.org/2001/XMLSchema-instance"</span>
|
||
<span class="na">xsi:schemaLocation=</span><span class="s">"http://pmd.sourceforge.net/ruleset/2.0.0 https://pmd.sourceforge.io/ruleset_2_0_0.xsd"</span><span class="nt">></span>
|
||
|
||
<span class="nt"><description></span>
|
||
My custom rules
|
||
<span class="nt"></description></span>
|
||
|
||
|
||
<span class="c"><!-- Your rules will come here --></span>
|
||
|
||
<span class="nt"></ruleset></span>
|
||
</code></pre></div></div>
|
||
|
||
<h3 id="referencing-a-single-rule">Referencing a single rule</h3>
|
||
|
||
<!-- TODO this could be better explained, eg first explain how a ruleset reference works, then rule reference, then go on showing single rule & bulk addition, then include/exclude patterns -->
|
||
|
||
<p>To use the built-in rules PMD provides, you need to add some <em>references</em> to them. Here’s a
|
||
basic rule reference:</p>
|
||
|
||
<div class="language-xml highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nt"><rule</span> <span class="na">ref=</span><span class="s">"category/java/errorprone.xml/EmptyCatchBlock"</span> <span class="nt">/></span>
|
||
</code></pre></div></div>
|
||
|
||
<p>Adding that element into the <code class="language-plaintext highlighter-rouge">ruleset</code> element adds the rule <a href="pmd_rules_java_errorprone.html#emptycatchblock">EmptyCatchBlock</a>
|
||
to your ruleset. This is a Java rule, so it will be executed on every Java file PMD encounters in
|
||
its search space.</p>
|
||
|

<p>How to read the <code class="language-plaintext highlighter-rouge">ref</code> attribute?</p>
|
||
|
||
<ul>
|
||
<li>
|
||
<p><code class="language-plaintext highlighter-rouge">category/java/errorprone.xml</code> is a reference to the Java category <code class="language-plaintext highlighter-rouge">errorprone</code>. Since PMD 6.0.0,
|
||
all PMD built-in rules are sorted in one of eight categories, which are consistent across languages:</p>
|
||
|
||
<ol>
|
||
<li><strong>Best Practices</strong>: These are rules which enforce generally accepted best practices.<br /></li>
|
||
<li><strong>Code Style</strong>: These rules enforce a specific coding style.<br /></li>
|
||
<li><strong>Design</strong>: Rules that help you discover design issues.<br /></li>
|
||
<li><strong>Documentation</strong>: These rules are related to code documentation.<br /></li>
|
||
<li><strong>Error Prone</strong>: Rules to detect constructs that are either broken, extremely confusing or prone to runtime errors.<br /></li>
|
||
<li><strong>Multithreading</strong>: These are rules that flag issues when dealing with multiple threads of execution.<br /></li>
|
||
<li><strong>Performance</strong>: Rules that flag suboptimal code.<br /></li>
|
||
<li><strong>Security</strong>: Rules that flag potential security flaws.”</li>
|
||
</ol>
|
||
</li>
|
||
</ul>

<div class="alert alert-success" role="alert"><i class="fa fa-check-square-o"></i> <b>Tip:</b> You can discover the available rules by language and category <a href="tag_rule_references.html">from this page</a></div>
|
||
|
||
<ul>
|
||
<li><code class="language-plaintext highlighter-rouge">EmptyCatchBlock</code> is simply the name of the rule. If there were no rule with that name within the specified
|
||
category, then PMD would fail before starting the analysis.</li>

|
||
|
||
<p>How you can configure individual rules is described on <a href="pmd_userdocs_configuring_rules.html">Configuring Rules</a>.</p>
|
||
|
||
<h3 id="bulk-adding-rules">Bulk-adding rules</h3>
|
||
|
||
<p>You can also reference rules in bulk by referencing a complete category or ruleset, possibly excluding certain rules, like in the following:</p>
|
||
|
||
<div class="language-xml highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nt"><rule</span> <span class="na">ref=</span><span class="s">"category/java/codestyle.xml"</span><span class="nt">></span>
|
||
<span class="nt"><exclude</span> <span class="na">name=</span><span class="s">"WhileLoopsMustUseBraces"</span><span class="nt">/></span>
|
||
<span class="nt"><exclude</span> <span class="na">name=</span><span class="s">"IfElseStmtsMustUseBraces"</span><span class="nt">/></span>
|
||
<span class="nt"></rule></span>
|
||
</code></pre></div></div>
|
||
|
||
<p>Here, the <code class="language-plaintext highlighter-rouge">ref</code> attribute references a whole category. You can also use a file system path or classpath relative path. In any case, the path must address an accessible ruleset XML file.</p>
|
||
|
||
<div class="alert alert-info" role="alert"><i class="fa fa-info-circle"></i> <b>Note:</b> Path separators in the source file path are normalized to be the <code class="language-plaintext highlighter-rouge">/</code> character within PMD, so the same ruleset can be used on multiple platforms transparently.</div>
|
||
|
||
<div class="alert alert-info" role="alert"><i class="fa fa-info-circle"></i> <b>Note:</b> Referencing a complete category or ruleset means, you’ll also get automatically any
|
||
changes for this ruleset. If new rules are added, then these are automatically activated for you. If rules
|
||
are deprecated, then these rules are automatically deactivated. This might or
|
||
not might be, what you want. This can happen, if a new version of PMD provides a new rule and or deprecates
|
||
existing rules. If you want to have
|
||
complete control over the rules, that you are using, then it is recommended to add each rule separately via
|
||
a single rule reference.</div>
|
||
|
||
<h3 id="filtering-the-processed-files">Filtering the processed files</h3>
|
||
|
||
<p>You can exclude some files from being processed by a ruleset using <strong>exclude patterns</strong>, with an optional overridding <strong>include pattern</strong>. A file will be excluded from processing <em>when there is a matching exclude pattern, but no matching include pattern</em>. This exclude/include technique works regardless of how PMD is used (e.g. command line, IDE, Ant), making it easier to keep application of your PMD rules consistent throughout your environment. Here is an example:</p>
|
||
|
||
<div class="language-xml highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="cp"><?xml version="1.0"?></span>
|
||
<span class="nt"><ruleset</span> <span class="na">name=</span><span class="s">"myruleset"</span>
|
||
<span class="na">xmlns=</span><span class="s">"http://pmd.sourceforge.net/ruleset/2.0.0"</span>
|
||
<span class="na">xmlns:xsi=</span><span class="s">"http://www.w3.org/2001/XMLSchema-instance"</span>
|
||
<span class="na">xsi:schemaLocation=</span><span class="s">"http://pmd.sourceforge.net/ruleset/2.0.0 https://pmd.sourceforge.io/ruleset_2_0_0.xsd"</span><span class="nt">></span>
|
||
<span class="nt"><description></span>My ruleset<span class="nt"></description></span>
|
||
|
||
<span class="nt"><exclude-pattern></span>.*/some/package/.*<span class="nt"></exclude-pattern></span>
|
||
<span class="nt"><exclude-pattern></span>.*/some/other/package/FunkyClassNamePrefix.*<span class="nt"></exclude-pattern></span>
|
||
<span class="nt"><include-pattern></span>.*/some/package/ButNotThisClass.*<span class="nt"></include-pattern></span>
|
||
|
||
<span class="c"><!-- Rules here ... --></span>
|

<span class="nt"></ruleset></span>
