+ <subsection name="Class Loaders">
+ <p>When writing plugins, you will need to control the class loaders that
+ are used to load your specified dependencies. The following table
+ shows the classloaders available:
+ </p>
+ <table>
+ <tr>
+ <th>Class loader</th>
+ <th>Description</th>
+ </tr>
+ <tr>
+ <td><default></td>
+ <td>
+ This class loader is used if none is specified in the dependency.
+ This means that the dependency is loaded into the plugin's class
+ loader, making it available to the plugin only.
+ </td>
+ </tr>
+ <tr>
+ <td><code>root</code></td>
+ <td>
+ This is the Ant class loader, and the most common override used in
+ a plugin. Use this if you need to specify a dependency used by a
+ custom Ant task used in the plugin.
+ </td>
+ </tr>
+ <tr>
+ <td><code>root.maven</code></td>
+ <td>
+ This is the Maven class loader. Use it if you wish to have the
+ dependency available to the Maven core.
+ </td>
+ </tr>
+ </table>
+ <p>To specify a classloader for a dependency, add a section similar to
+ the following to your plugin's project.xml:
+ </p>
+ <source><![CDATA[
+<dependency>
+ <groupId>jaxb</groupId>
+ <artifactId>jaxb-xjc</artifactId>
+ <properties>
+ <classloader>root</classloader>
+ </properties>
+</dependency>
+ ]]></source>
+ <p>You should also note that the same properties can be used in your
+ projects, not just plugins. This may be required if you are writing
+ custom scripts in <code>maven.xml</code>.
+ </p>
