How to get line by line coverage xml file in Emma- maven project

I am using the Emma tool in Maven project. Emma creates line by line code coverage in HTML file, it does not display line by line code coverage XML file. It gives only a summary XML file. Is there a way to keep or generate line by line code coverage XML file in Emma?

I have entered following plugin in my pom.xml

<reporting>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-project-info-reports-plugin</artifactId>
      <version>2.7</version>
      <configuration>
        <dependencyLocationsEnabled>false</dependencyLocationsEnabled>
      </configuration>
    </plugin>
    <plugin>
      <groupId>org.codehaus.mojo</groupId>
      <artifactId>emma-maven-plugin</artifactId>
      <version>1.0-alpha-3</version>
      <inherited>true</inherited>
    </plugin>
  </plugins>
</reporting>

Am I missing any configuration? If so where should I enter it in pom? (A complete pom.xml file will be appreciated).

I have created my project using Eclipse and ran it in cmd using the code:

mvn emma:emma

also i have entered following inside the Emma-maven pluggin

<configuration>
            <outputDirectory>${project.build.directory}</outputDirectory>
        </configuration>

Yes, you can set the property maven.emma.report.xml to true to generate a XML report (it is false by default). The file target/coverage.xml will be generated.

Sample command:

mvn emma:emma -Dmaven.emma.report.xml=true
