title: How do I filter test resources in maven?
body: <p>I have the following <code>pom.xml</code>. When I run <code>mvn clean resources:testResources</code>, my test resources aren't being <a href="https://maven.apache.org/plugins/maven-resources-plugin/examples/filter.html" rel="noreferrer">filtered</a> (replacing placeholders in resources before they are put, in their modified form, into the output folder). Why?</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"&gt;
      &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt;
      &lt;groupId&gt;com.example&lt;/groupId&gt;
      &lt;artifactId&gt;foo&lt;/artifactId&gt;
      &lt;version&gt;0.0.1&lt;/version&gt;
      &lt;packaging&gt;jar&lt;/packaging&gt;
      &lt;name&gt;foo&lt;/name&gt;
  
      &lt;dependencies&gt;
          &lt;dependency&gt;
              &lt;groupId&gt;junit&lt;/groupId&gt;
              &lt;artifactId&gt;junit&lt;/artifactId&gt;
              &lt;version&gt;4.11&lt;/version&gt;
              &lt;scope&gt;test&lt;/scope&gt;
          &lt;/dependency&gt;
      &lt;/dependencies&gt;
  
      &lt;build&gt;
          &lt;resources&gt;
              &lt;resource&gt;
                  &lt;directory&gt;src/test/resources&lt;/directory&gt;
                  &lt;filtering&gt;true&lt;/filtering&gt;
              &lt;/resource&gt;
          &lt;/resources&gt;
      &lt;/build&gt;
  &lt;/project&gt;
