|
||
<p>The easiest way to run PMD is to just use a build plugin in your favorite build tool
|
||
like <a href="pmd_userdocs_tools_ant.html">Apache Ant</a>, <a href="pmd_userdocs_tools_maven.html">Apache Maven</a> or
|
||
<a href="pmd_userdocs_tools_gradle.html">Gradle</a>.</p>
|
||
|
||
<p>There are also many integrations for IDEs available, see <a href="pmd_userdocs_tools.html">Tools</a>.</p>
|
||
|
||
<p>If you have your own build tool or want to integrate PMD in a different way, you can call PMD programmatically,
|
||
as described here.</p>
|
||
|
||
<h2 id="dependencies">Dependencies</h2>
|
||
|
||
<p>You’ll need to add the dependency to the language, you want to analyze. For Java, it will be
|
||
<code class="language-plaintext highlighter-rouge">net.sourceforge.pmd:pmd-java</code>. If you use Maven, you can add a new (compile time) dependency like this:</p>
|
||
|
||
<div class="language-xml highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nt"><dependency></span>
|
||
<span class="nt"><groupId></span>net.sourceforge.pmd<span class="nt"></groupId></span>
|
||
<span class="nt"><artifactId></span>pmd-java<span class="nt"></artifactId></span>
|
||
<span class="nt"><version></span>${pmdVersion}<span class="nt"></version></span>
|
||
<span class="nt"></dependency></span>
|
||
</code></pre></div></div>
|
||
|
||
<p>Note: You’ll need to select a specific version. This is done in the example via the property <code class="language-plaintext highlighter-rouge">pmdVersion</code>.</p>
|
||
|
||
<p>This will transitively pull in the artifact <code class="language-plaintext highlighter-rouge">pmd-core</code> which contains the API.</p>
|
||
|
||
<h2 id="command-line-interface">Command line interface</h2>
|
||
|
||
<p>The easiest way is to call PMD with the same interface as from command line. The main class is
|
||
<code class="language-plaintext highlighter-rouge">net.sourceforge.pmd.PMD</code>:</p>
|
||
|
||
<div class="language-java highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="kn">import</span> <span class="nn">net.sourceforge.pmd.PMD</span><span class="o">;</span>

|

|
||
<span class="s">"-d"</span><span class="o">,</span> <span class="s">"/home/workspace/src/main/java/code"</span><span class="o">,</span>
|
||
<span class="s">"-R"</span><span class="o">,</span> <span class="s">"rulesets/java/quickstart.xml"</span><span class="o">,</span>
|

<span class="s">"-f"</span><span class="o">,</span> <span class="s">"xml"</span><span class="o">,</span>

|

<span class="o">}</span>
|

<span class="o">}</span>
|

</code></pre></div></div>

<h2 id="programmatically-variant-2">Programmatically, variant 2</h2>
|
||
|
||
<p>This gives you more control over which files are processed, but is also more complicated.
|
||
You can also provide your own custom renderers.</p>
|
||
|
||
<ol>
|
||
<li>
|
||
<p>First we create a <code class="language-plaintext highlighter-rouge">PMDConfiguration</code>. This is currently the only way to specify a ruleset:</p>
|
||
|
||
<div class="language-java highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nc">PMDConfiguration</span> <span class="n">configuration</span> <span class="o">=</span> <span class="k">new</span> <span class="nc">PMDConfiguration</span><span class="o">();</span>
|

<span class="n">configuration</span><span class="o">.</span><span class="na">setMinimumPriority</span><span class="o">(</span><span class="nc">RulePriority</span><span class="o">.</span><span class="na">MEDIUM</span><span class="o">);</span>

<span class="n">configuration</span><span class="o">.</span><span class="na">setRuleSets</span><span class="o">(</span><span class="s">"rulesets/java/quickstart.xml"</span><span class="o">);</span>
|
||
</code></pre></div> </div>
|
||
</li>
|
||
<li>
|
||
<p>In order to support type resolution, PMD needs to have access to the compiled classes and dependencies
|
||
as well. This is called “auxclasspath” and is also configured here.
|
||
Note: you can specify multiple class paths separated by <code class="language-plaintext highlighter-rouge">:</code> on Unix-systems or <code class="language-plaintext highlighter-rouge">;</code> under Windows.</p>
|
||
|
||
<div class="language-java highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="n">configuration</span><span class="o">.</span><span class="na">prependClasspath</span><span class="o">(</span><span class="s">"/home/workspace/target/classes:/home/.m2/repository/my/dependency.jar"</span><span class="o">);</span>
|
||
</code></pre></div> </div>
|
||
</li>
|
||
<li>
|
||
<p>Then we need to load the rulesets. This is done by using the configuration, taking the minimum priority into
|
||
account:</p>
|
||
|
||
<div class="language-java highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nc">RuleSetLoader</span> <span class="n">ruleSetLoader</span> <span class="o">=</span> <span class="nc">RuleSetLoader</span><span class="o">.</span><span class="na">fromPmdConfig</span><span class="o">(</span><span class="n">configuration</span><span class="o">);</span>

|
||
</code></pre></div> </div>
|
||
</li>
|
||
<li>
|
||
<p>PMD operates on a list of <code class="language-plaintext highlighter-rouge">DataSource</code>. You can assemble a own list of <code class="language-plaintext highlighter-rouge">FileDataSource</code>, e.g.</p>
|
||
|
||
<div class="language-java highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nc">List</span><span class="o"><</span><span class="nc">DataSource</span><span class="o">></span> <span class="n">files</span> <span class="o">=</span> <span class="nc">Arrays</span><span class="o">.</span><span class="na">asList</span><span class="o">(</span><span class="k">new</span> <span class="nc">FileDataSource</span><span class="o">(</span><span class="k">new</span> <span class="nc">File</span><span class="o">(</span><span class="s">"/path/to/src/MyClass.java"</span><span class="o">)));</span>
|
||
</code></pre></div> </div>
|
||
</li>
|
||
<li>
|
||
<p>For reporting, you can use a built-in renderer, e.g. <code class="language-plaintext highlighter-rouge">XMLRenderer</code> or a custom renderer implementing
|
||
<code class="language-plaintext highlighter-rouge">Renderer</code>. Note, that you must manually initialize
|
||
the renderer by setting a suitable <code class="language-plaintext highlighter-rouge">Writer</code> and calling <code class="language-plaintext highlighter-rouge">start()</code>. After the PMD run, you need to call
|
||
<code class="language-plaintext highlighter-rouge">end()</code> and <code class="language-plaintext highlighter-rouge">flush()</code>. Then your writer should have received all output.</p>
|
||
|
||
<div class="language-java highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nc">StringWriter</span> <span class="n">rendererOutput</span> <span class="o">=</span> <span class="k">new</span> <span class="nc">StringWriter</span><span class="o">();</span>

|
||
</code></pre></div> </div>
|
||
</li>
|
||
<li>
|
||
<p>Now, all the preparations are done, and PMD can be executed. This is done by calling
|
||
<code class="language-plaintext highlighter-rouge">PMD.processFiles(...)</code>. This method call takes the configuration, the rulesets, the files
|
||
to process, and the list of renderers. Provide an empty list, if you don’t want to use
|
||
any renderer. Note: The auxclasspath needs to be closed explicitly. Otherwise the class or jar files may
|
||
remain open and file resources are leaked.</p>
