Jacoco Report are not generated in the site - maven

Question

Jacoco reports are not generated when mvn builds the site.
Jacoco reports are generated in my target folder at target\site\jacoco , but somehow I am not able to see "Jacoco Tests" option under "Project Reports" when I try to build the jar site
The only thing I see in the log while generating the site is as below :
[INFO] <<< clirr-maven-plugin:2.6.1:clirr # data-binding <<<
[INFO] configuring report plugin com.cerner.engineering:maven-cerner-ml-dependency-plugin:1.1.1
[INFO] configuring report plugin org.jacoco:jacoco-maven-plugin:0.7.4.201502262128
[INFO] Skipping JaCoCo execution due to missing execution data file:C:\MSVCWorkspace\br-hla-april-data-binding\target\jacoco.exec
I am using the command mvn clean install site
This is how I have configure jacoco in my pom.xml in my build section :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>${surefire.plugin.version}</version>
<configuration>
<excludes>
<exclude>**/*Suite*.java</exclude>
</excludes>
<forkCount>1</forkCount>
<reuseForks>false</reuseForks>
<argLine>-Xms64m -Xmx512m -XX:MaxPermSize=256M -enableassertions -XX:+HeapDumpOnOutOfMemoryError ${jacoco.argLine}</argLine>
<junitArtifactName>junit:junit-dep</junitArtifactName>
</configuration>
</plugin>
Jacoco plugin is called like :
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>${jacoco.version}</version>
<configuration>
<destFile>${basedir}/target/coverage-reports/jacoco-unit.exec</destFile>
<dataFile>${basedir}/target/coverage-reports/jacoco-unit.exec</dataFile>
</configuration>
<executions>
<execution>
<id>jacoco-initialize</id>
<goals>
<goal>prepare-agent</goal>
</goals>
<configuration>
<propertyName>jacoco.argLine</propertyName>
</configuration>
</execution>
<execution>
<id>jacoco-site</id>
<phase>package</phase>
<goals>
<goal>report</goal>
</goals>
</execution>
</executions>
</plugin>
I am not sure what is causing this issue , not to generate Jacoco reports on my site.
Although I am able to see the below in my logs
[INFO]
[INFO] --- jacoco-maven-plugin:0.7.4.201502262128:prepare-agent (default-cli) # data-binding ---
[INFO] argLine set to -javaagent:C:\\_repository\\org\\jacoco\\org.jacoco.agent\\0.7.4.201502262128\\org.jacoco.agent-0.7.4.201502262128-runtime.jar=destfile=C:\\target\\coverage-reports\\jacoco-unit.exec
Thanks !!!

I was able to fix by calling plugin as below
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>${jacoco.version}</version>
<configuration>
<dataFile>${basedir}/target/coverage-reports/jacoco-unit.exec</dataFile>
</configuration>
<executions>
<execution>
<id>jacoco-initialize</id>
<goals>
<goal>prepare-agent</goal>
</goals>
<configuration>
<propertyName>jacoco.argLine</propertyName>
</configuration>
</execution>
</executions>
</plugin>
