Here is an example Ant XML build file illustrating configuration of Note that the report type is specified as “html”.

    <target name="runCodeNarc">
            <report type="html">
                <option name="outputFile" value="reports/CodeNarcAntReport.html" />
                <option name="title" value="My Sample Code" />
