Maven not outputting junit CHECKSTYLE report - maven

Question

After default config, maven is only outputting the Checkstyle report for source classes, not Junit test classes. Note I'm not looking for the surefire test report output.
from pom.xml:
<reporting>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-checkstyle-plugin</artifactId>
<version>2.17</version>
<reportSets>
<reportSet>
<reports>
<report>checkstyle</report>
</reports>
</reportSet>
</reportSets>
<configuration>
<configLocation>src/main/resources/apcheckstyle.xml</configLocation>
<module name="LineLength">
<property name="max" value="120"/>
</module>
</configuration>
</plugin>
</plugins>
I changed dependency scope for junit from test to compile:
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>compile</scope>
</dependency>
Maven is configured to generate the checkstyle reports using the mvn site plugin.
I tried adding a user property includeTestResources as true, but this did not help. The documentation states that the default value is true, so I took it out.
Here is the maven output during checkstyle generation.
from javadocs:
Generating C:\Users\Administrator\Projects\lht657aws\target\site\testapidocs\help-doc.html...
checkstyle plugin runs:
[INFO] Generating "Checkstyle" report --- maven-checkstyle-plugin:2.17
[INFO] There are 210 errors reported by Checkstyle 6.11.2 with src/main/resources/apcheckstyle.xml ruleset.
is following the problem-? all the java under src is getting processed, just java under test is being skipped:
[WARNING] Unable to locate Source XRef to link to - DISABLED
after checkstyle, maven project info report starts
[INFO] Generating "Dependencies" report --- maven-project-info-reports-plugin:2.9

Add the Maven Surefire Report plugin to your pom XML
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-report-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<outputDirectory>path/to/the/report</outputDirectory>
</configuration>
</plugin>
And add the goal surefire-report:report to your maven call
See the documentation here: Maven Surefire Report Plugin
EDIT
I've misunderstood the question, try to add this section with desired configurations to your pom.
<reporting>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-checkstyle-plugin</artifactId>
<version>2.17</version>
<reportSets>
<reportSet>
<id>main_checks</id>
<reports>
<report>checkstyle</report>
</reports>
<configuration>
<sourceDirectory>${project.build.sourceDirectory}</sourceDirectory>
<includeTestSourceDirectory>false</includeTestSourceDirectory>
<configLocation>config/maven_checks.xml</configLocation>
<outputDirectory>${project.reporting.outputDirectory}/main-checks/</outputDirectory>
</configuration>
</reportSet>
<reportSet>
<id>test_checks</id>
<reports>
<report>checkstyle</report>
</reports>
<configuration>
<sourceDirectory></sourceDirectory>
<testSourceDirectory>${project.build.testSourceDirectory}</testSourceDirectory>
<includeTestSourceDirectory>true</includeTestSourceDirectory>
<configLocation>config/sun_checks.xml</configLocation>
<outputDirectory>${project.reporting.outputDirectory}/test-checks/</outputDirectory>
</configuration>
</reportSet>
</reportSets>
</plugin>
</plugins>
</reporting>

Maven sure fire plugin is used for generating the Test reports. See the additional documentation here:
http://maven.apache.org/surefire/maven-surefire-report-plugin/
You need to include this plugin in your POM.xml and provide path to create reports (generally a directory in project). While making the build make sure you are including goal for this.
