    <!-- Eclipse-Only Suppression Filter Configuration / Fails for Maven 
        Commandline Maven command-line build uses pom.xml suppressionLocation setting 
        in the checkstyle configuration. Eclipse checkstyle does not recognize the 
        pom.xml setting, only the checkstyle.xml SuppressionFilter module here. But 
        Maven command-line does not compile with the following because no variable 
        is defined to locate the supporessions.xml in a way that works consistently 
        regardless of where invoked (from root of project or cd into individual projects. 
        You can set pom.xml PropertiesLocation tag with a .properties file containing 
        key=value pairs for such variables, but they are not relative to the checkstyle.xml 
        location. DISABLED: Enable only if you want to see the same exclusions from 
        eclipse, but will not build from command-line. <module name="SuppressionFilter">
