Is it possible to have two mainClass in the pom.xml or be able to run two classes in the same pom.xml?

I am working on a java project. We use Continuous Integration with maven 3, svn and Jenkins. We have one utility java project in which we've implemented some useful features. We build a jenkins tasks to run the mainClass in this project. Here is the code snippet on project pom.xml :

<plugin>
           ..
                <artifactId>exec-maven-plugin</artifactId>
                <version>1.2.1</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>java</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <mainClass>com.ent.uti.Cleaner</mainClass>
                    <arguments>
                        <argument>value1</argument>
                        <argument>value2</argument>
                    </arguments>
                </configuration>
            </plugin>

This class is execute in jenkins task configuration :

mvn exec:java -o -f cleaner/pom.xml 

I am wondering if it is possible for me to implement some features in the same project and add another task in Jenkins ? Is it possible to have two main classes in the same pom.xml configuration ?

I know i could create another project and configure a mainClass in the pom. I think doing so is not a good idea. The both task are independant so it's not suitable to run the both class one after another.

Thanks for reading.
