<h2 id="type-resolution">Type resolution</h2>
<p>Since PMD 6.30.0 support for type resolution has been added.</p>
<p>The Visualforce AST now can resolve the data type of Visualforce expressions that reference
Apex Controller properties and Custom Object fields. This feature improves the precision of existing rules,
like <a href="pmd_rules_vf_security.html#vfunescapeel"><code class="language-plaintext highlighter-rouge">VfUnescapeEl</code></a>.</p>
<p>This can be configured using two environment variables:</p>
<ul>
<li>
<p><code class="language-plaintext highlighter-rouge">PMD_VF_APEXDIRECTORIES</code>: Comma separated list of directories for Apex classes. Absolute or relative
to the Visualforce directory. Default is <code class="language-plaintext highlighter-rouge">../classes</code>. Specifying an empty string will disable data type
resolution for Apex Controller properties.</p>
</li>
<li>
<p><code class="language-plaintext highlighter-rouge">PMD_VF_OBJECTSDIRECTORIES</code>: Comma separated list of directories for Custom Objects. Absolute or relative
to the Visualforce directory. Default is <code class="language-plaintext highlighter-rouge">../objects</code>. Specifying an empty string will disable data type
resolution for Custom Object fields.</p>
</li>
</ul>
<p>This feature is experimental, in particular, expect changes to the way the configuration is specified.
We’ll probably extend the CLI instead of relying on environment variables in a future version.</p>
<h3 id="sample-usage">Sample usage</h3>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>PMD_VF_APEXDIRECTORIES=../classes \
PMD_VF_OBJECTSDIRECTORIES=../objects \
run.sh pmd -d $GITHUB_WORKSPACE/force-app/main/default/pages \
-R category/vf/security.xml/VfUnescapeEl -f text
</code></pre></div></div>
<p>If you run with debug logging turned on, you might see log messages like this:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>Okt. 14, 2021 11:30:44 AM net.sourceforge.pmd.lang.vf.VfExpressionTypeVisitor visit
FINE: Unable to determine type for: Account.NotFoundField__c
</code></pre></div></div>
<p>This means, that type resolution didn’t work. Maybe the provided directories are missing or do not contain
the needed data.</p>
