You have to configure the included maven-jar-plugin as per the documentation.

   <project>
      ...
      <build>
        <plugins>
          ...
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
              <includes>
                <include>**/foo/*</include>
              </includes>
              <excludes>
                <exclude>**/bar/*</exclude>
              </excludes>
            </configuration>
          </plugin>
          ...
        </plugins>
      </build>
      ...
    </project>
