             When referring to a directory, additional properties help adjust the scope of the exclusion:
             <ul>
                 <li>glob - only entries matching this <a href="https://docs.oracle.com/javase/tutorial/essential/io/fileOps.html#glob">glob pattern</a> are excluded</li>
                 <li>entryType - type of entries excluded from the scan</li>
                 <li>matcherType - entry property on which the glob matching is applied</li>
             </ul>
-            By default, targeting a directory excludes everything underneath it.<br/>

             Examples :

               <li><code>&lt;exclude&gt;src/main/doc&lt;/exclude&gt;</code> : excludes everything under : ${project.basedir}/src/main/doc</li>

               <li><code>&lt;exclude glob="package-info.java"&gt;&lt;/exclude&gt;</code> : excludes all the files named package-info.java</li>
               <li><code>&lt;exclude glob="src/main/resources&#x2F;**.txt" entryType="FILE" matcherType="PATH" &gt;&lt;/exclude&gt;</code> : excludes all the text files located under the "resources" folder</li>
