This parameter expects that the contents of the location conform to the xml format (Checkstyle Checker module) configuration of rulesets. This parameter is resolved as resource, URL, then file. If successfully resolved, the contents of the configuration is copied into the `${project.build.directory}/checkstyle-configuration.xml` file before being passed to Checkstyle as a configuration.

You need to use ${checkstyle.header.file} in your Checkstyle xml configuration to reference the name of this header file. For instance: `<module name="RegexpHeader"> <property name="headerFile" value="${checkstyle.header.file}"/> </module>` Default value is: `LICENSE.txt`. User property is: `checkstyle.header.file`.

If successfully resolved, the contents of the properties location is copied into the `${project.build.directory}/checkstyle-checker.properties` file before being passed to Checkstyle for loading. The contents of the `propertiesLocation` will be made available to Checkstyle for specifying values for parameters within the xml configuration (specified in the `configLocation` parameter). User property is: `checkstyle.properties.location`.

useFile	`File`	`-`	If `null`, the Checkstyle plugin will display violations on stdout. Otherwise, a text file will be created with the violations.
xrefLocation	`File`	`-`	Location of the Xrefs to link to. Default value is: `${project.reporting.outputDirectory}/xref`.
