    copied!<p>Your <code>configuration</code> element is defined inside an <code>execution</code> and thus applies to this <code>execution</code> only. </p> <p>So either call <code>mvn initialize</code> (or a phase posterior to <code>initialize</code>) to use the <code>configuration</code> of your current <code>execution</code> binding. </p> <p>Or use a global <code>configuration</code>:</p> <pre><code> &lt;plugin&gt; &lt;groupId&gt;org.codehaus.mojo&lt;/groupId&gt; &lt;artifactId&gt;properties-maven-plugin&lt;/artifactId&gt; &lt;version&gt;1.0-alpha-2&lt;/version&gt; &lt;configuration&gt; &lt;files&gt; &lt;file&gt;etc/config/dev.properties&lt;/file&gt; &lt;/files&gt; &lt;/configuration&gt; ... &lt;/plugin&gt; </code></pre> <p>And then call </p> <pre><code>mvn properties:read-project-properties </code></pre> <p>But that wouldn't make much sense in the particular case of this plugin (you want the properties to be available during the build) so this leaves you with the first solution.</p> <hr> <p><strong>Update:</strong> I did a test on my side and, indeed, with the following POM:</p> <pre><code>&lt;project&gt; &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt; &lt;groupId&gt;com.stackoverflow&lt;/groupId&gt; &lt;artifactId&gt;Q2664362&lt;/artifactId&gt; &lt;version&gt;1.0-SNAPSHOT&lt;/version&gt; &lt;build&gt; &lt;plugins&gt; &lt;plugin&gt; &lt;groupId&gt;org.codehaus.mojo&lt;/groupId&gt; &lt;artifactId&gt;properties-maven-plugin&lt;/artifactId&gt; &lt;version&gt;1.0-alpha-2&lt;/version&gt; &lt;executions&gt; &lt;execution&gt; &lt;phase&gt;initialize&lt;/phase&gt; &lt;goals&gt; &lt;goal&gt;read-project-properties&lt;/goal&gt; &lt;/goals&gt; &lt;configuration&gt; &lt;files&gt; &lt;file&gt;etc/config/dev.properties&lt;/file&gt; &lt;/files&gt; &lt;/configuration&gt; &lt;/execution&gt; &lt;/executions&gt; &lt;/plugin&gt; &lt;/plugins&gt; &lt;/build&gt; &lt;dependencies&gt; &lt;dependency&gt; &lt;groupId&gt;junit&lt;/groupId&gt; &lt;artifactId&gt;junit&lt;/artifactId&gt; &lt;version&gt;${junit.version}&lt;/version&gt; &lt;scope&gt;test&lt;/scope&gt; &lt;/dependency&gt; &lt;/dependencies&gt; &lt;/project&gt; </code></pre> <p>Running <code>mvn test</code> won't work: maven will try to download <code>junit:jar:${junit.version}</code> (i.e. it doesn't use the value of the property) and this will obviously fail.</p> <pre> $ mvn test [INFO] Scanning for projects...
