How to exclude dependency in a Maven plugin?

Question

I have a project that needs the following Maven jibx plugin:

  <build>     <plugins>       <plugin>         <groupId>org.jibx</groupId>         <artifactId>maven-jibx-plugin</artifactId>         <version>1.2.2</version>         ...       </plugin>     </plugins>   </build> 

Inside the jibx plugin pom, there is a xpp3 dependency which I want to exclude from my project build process (due to some reason I cannot have it inside my private repository).

Is there a way to config my pom.xml (not the plugin pom) to exclude that dependency?

EDIT: I tried to remove the xpp3 dependency from the plugin pom and the project could be built successfully, so I know the dependency is not mandatory.

Here is an example where the jetty-maven-plugin has a dependency on jtidy replaced with a newer version:

    <plugin>         <groupId>org.mortbay.jetty</groupId>         <artifactId>jetty-maven-plugin</artifactId>         <dependencies>           <dependency>             <groupId>net.sf.jtidy</groupId>             <artifactId>jtidy</artifactId>             <version>r938</version>           </dependency>           <dependency>             <groupId>org.apache.maven.plugin-tools</groupId>             <artifactId>maven-plugin-tools-api</artifactId>             <version>2.5.1</version>             <exclusions>               <exclusion>                 <groupId>jetty</groupId>                 <artifactId>jetty</artifactId>               </exclusion>             </exclusions>           </dependency>         </dependencies> [...]       </plugin>
