How to prioritize or order the Maven plugin Execution?

Question

I define the Maven plugins in POM.xml as follows:

<build>
    <outputDirectory>reports/maven/classes</outputDirectory>
    <testOutputDirectory>reports/maven/test-classes</testOutputDirectory>
    <plugins>
        <plugin>
            <artifactId>maven-clean-plugin</artifactId>

                <filesets>

                        <directory>${basedir}/reports/maven/mail</directory>
                        <includes>
                            <include>**/*</include>
                        </includes>
                        <followSymlinks>false</followSymlinks>
                    </fileset>
                </filesets>
            </configuration>
        </plugin>

                </execution>
            </executions>
        </plugin>

    </plugins>
</build>

But the maven plugin, 'maven-resources-plugin' seems to run at the first whereas I need the same to run at the last. Please provide the work around to post-run 'maven-resources-plugin'. Thanks in advance!

The following link helps you to order the maven plugin execution. https://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html

Add proper < phase > tag to achieve it.
