It allows to "automatically measure the quality of a design in terms of its extensibility, reusability, and maintainability to effectively manage and control package dependencies."</p> <p>Source file directories are defined by nested <code><sourcespath></code>. Class file directories are defined by nested <code><classespath></code>. See <a href="#nested">nested elements</a>.</p> <p>Optionally, you can also set the <var>outputfile</var> name where the output is stored. By default the task writes its report to the standard output.</p> <p>The task requires at least the JDepend 1.2 version.</p> <h3>Parameters</h3> <table class="attr"> <tr> <th scope="col">Attribute</th> <th scope="col">Description</th> <th scope="col">Required</th> </tr> <tr> <td>outputfile</td> <td>The output file name. If not set, the output is printed on the standard output.</td> <td>No</td> </tr> <tr> <td>format</td> <td>The format to write the output in, either <q>text</q> (default) or <q>xml</q></td> <td>No; the default is <q>text</q></td> </tr> <tr> <td>fork</td> <td>Run the tests in a separate JVM.</td> <td>No; default is <q>off</q></td> </tr> <tr> <td>haltonerror</td> <td>Stop the build process if an error occurs during the <code>jdepend</code> analysis.</td> <td>No; default is <q>off</q></td> </tr> <tr> <td>timeout</td> <td>Cancel the operation if it doesn't finish in the given time (measured in milliseconds).</td> <td>No, ignored if <var>fork</var> is <q>false</q></td> </tr> <tr> <td>jvm</td> <td>The command used to invoke JVM. The command is resolved by <code>java.lang.Runtime.exec()</code>.</td> <td>No; default <kbd>java</kbd>, ignored if <var>fork</var> is <q>false</q></td> </tr> <tr> <td>dir</td> <td>The directory to invoke JVM in.</td> <td>No, ignored if <var>fork</var> is <q>false</q></td> </tr> <tr> <td>includeruntime</td> <td>Implicitly add the classes required to run <code>jdepend</code> in forked mode. <em>Since Apache Ant 1.6</em>.</td> <td>No; default is <q>no</q>, ignored if <var>fork</var> is <q>false</q></td> </tr> <tr> <td>classpathref</td> <td>the <var>classpath</var> to use, given as reference to a path defined elsewhere.</td> <td>No</td> </tr> </table> <h3 id="nested">Parameters specified as nested elements</h3> <p><code>jdepend</code> supports four nested elements: <code><classpath></code>, <code><classespath></code> and <code><sourcespath></code>, that represent <a href="../using.html#path">path-like structures</a>, and <code><exclude></code>.</p> <p><code><sourcespath></code> is used to define the paths of the source code to analyze, but it is deprecated. With version 2.5 of JDepend, only class files are analyzed. The nested element <code><classespath></code> replaces <code><sourcespath></code> and is used to define the paths of compiled class code to analyze; the <code><sourcespath></code> variable is still available in case you are using an earlier version of JDepend. The <code><exclude></code> element can be used to set packages to ignore (requires JDepend 2.5 or above).</p> <h3>Examples</h3> <p>Invoke JDepend on the <samp>build</samp> directory, writing the output on the standard output. The classpath is defined using a reference.</p> <pre> <jdepend classpathref="base.path"> <classespath> <pathelement location="build"/> </classespath> </jdepend></pre> <p>This invoke JDepend in a separate JVM on the <samp>src</samp> and <samp>testsrc</samp> directories, writing the output to the <samp>docs/jdepend.xml</samp> file in XML format. The classpath is defined using nested elements.</p> <pre> <jdepend outputfile="docs/jdepend.xml" fork="yes" format="xml"> <sourcespath> <pathelement location="src"/> </sourcespath> <classpath> <pathelement location="classes"/> <pathelement location="lib/jdepend.jar"/> </classpath> </jdepend></pre> <p>Invoke JDepend with the build directory as the base for class files to analyze, and ignore all classes in the <samp>java.*</samp> and <samp>javax.*</samp> packages.</p> <pre> <jdepend classpathref="base.path"> <exclude name="java.*> <exclude name="javax.*> <classespath> <pathelement location="build"/> </classespath> </jdepend></pre> </body> </html>
