title: Custom checkstyle configuration ignores standard rules?
body: <p>I'm setting up the code style checking for my project. There are some standard rules I want to customize. For that, I created a file named <code>checkstyle.xml</code>:</p>
  
  
  
  <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0"?&gt;
  &lt;!DOCTYPE module PUBLIC
      "-//Puppy Crawl//DTD Check Configuration 1.3//EN" 
      "http://www.puppycrawl.com/dtds/configuration_1_3.dtd"&gt;
  &lt;module name="Checker"&gt;
      &lt;module name="SuppressionFilter"&gt;
          &lt;property name="file" value="${checkstyle.suppressions.file}"/&gt;
      &lt;/module&gt;
      &lt;module name="TreeWalker"&gt;
          &lt;module name="HiddenField"&gt;
              &lt;property name="ignoreSetter" value="true"/&gt;
              &lt;property name="ignoreConstructorParameter" value="true"/&gt;
          &lt;/module&gt;
      &lt;/module&gt;
  &lt;/module&gt;
  </code></pre>
  
  <p>In project's <code>pom.xml</code>, I configured maven checkstyle plugin:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;plugin&gt;
      &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
      &lt;artifactId&gt;maven-checkstyle-plugin&lt;/artifactId&gt;
      &lt;version&gt;2.17&lt;/version&gt;
      &lt;executions&gt;
          &lt;execution&gt;
              &lt;phase&gt;install&lt;/phase&gt;
              &lt;goals&gt;
                  &lt;goal&gt;checkstyle&lt;/goal&gt;
              &lt;/goals&gt;
          &lt;/execution&gt;
      &lt;/executions&gt;
      &lt;configuration&gt;
          &lt;consoleOutput&gt;${checkstyle.printErrors}&lt;/consoleOutput&gt;
          &lt;configLocation&gt;checkstyle.xml&lt;/configLocation&gt;
          &lt;suppressionsLocation&gt;checkstyle-suppressions.xml&lt;/suppressionsLocation&gt;
          &lt;suppressionsFileExpression&gt;checkstyle.suppressions.file&lt;/suppressionsFileExpression&gt;
      &lt;/configuration&gt;
  &lt;/plugin&gt;
  </code></pre>
  
  <p>Now, only the <code>HiddenField</code> check is applied, all the other checks from <code>sun_checks.xml</code> are turned off. If I turn the custom checkstyle.xml off in plugin settings, the standard checks are applied again.</p>
  
  <p>Question is, how to apply the standard checks, modifying the settings for one or some of them?</p>
