CodeNarc - Ant Task


The CodeNarc Ant Task is implemented by the org.codenarc.ant.CodeNarcTask class.


Attribute Description Required
ruleSetFiles The paths to the Groovy or XML RuleSet definition files. This can be a single file path, or multiple paths separated by commas. By default, the paths specified are relative to the classpath. But each path may be optionally prefixed by any of the valid prefixes, such as “file:” (to load from a relative or absolute filesystem path), or “http:”. If it is a URL, its path may be optionally URL-encoded. That can be useful if the path contains any problematic characters, such as comma (‘,’) or hash (‘#’). For instance: “file:src/test/resources/RuleSet-,#.txt” can be encoded as: “file:src%2Ftest%2Fresources%2FRuleSet-%2C%23.txt” See URLEncoder#encode(java.lang.String, java.lang.String). Yes
maxPriority1Violations The maximum number of priority 1 violations allowed before failing the build (throwing a BuildException). No
maxPriority2Violations The maximum number of priority 2 violations allowed before failing the build (throwing a BuildException). No
maxPriority3Violations The maximum number of priority 3 violations allowed before failing the build (throwing a BuildException). No
plugins The optional list of CodeNarcPlugin class names to register, separated by commas. No
excludeBaseline The path to a baseline violations report (report type “baseline”) If set, then all violations specified within that report are excluded (filtered) from the current CodeNarc run. If null/empty, then do nothing. See Baseline Report. No
classpathRef The reference to a path element which is to be used as classpath when compiling analysed sources (useful with Enhanced Classpath Rules). No
failOnError Boolean that indicates whether to terminate and fail the task (throwing a BuildException) if any errors occur parsing source files (true), or just log the errors (false). It defaults to false. No

Report Nested Element

The report nested element defines the format and output file for the analysis report.

Attribute Description Required
type The type of the output report. Must be either one of the predefined type names: “html”, “xml”, “text”, “console”, “ide” or else the fully-qualified class name of a class (accessible on the classpath) that implements the interface. Yes


Option Nested Element

The <option> element is a child of the <report> element and defines a report-specific option for a report. You specify the option name and value as attributes within the <option> element. See the Example below.

Fileset Nested Element

At least one <fileset> nested element is required, and is used to specify the source files that CodeNarc should analyze. This is the standard Ant <FileSet>, and is quite powerful and flexible. See the Apache Ant Manual for more information on <FileSets>.

Classpath Nested Element

An optional classpath nested element can be utilized to specify contents of the classpath to be used when CodeNarc compiles classes it analyses. Having control over that classpath is essential when using Enhanced Classpath Rules. It is a standard Ant Path element.


Here is an example Ant XML build file.

    <taskdef name="codenarc" classname="org.codenarc.ant.CodeNarcTask"/>
    <target name="runCodeNarc">
            <report type="html">
                <option name="outputFile" value="reports/CodeNarcAntReport.html" />
                <option name="title" value="My Sample Code" />
            <fileset dir="src">
                <include name="**/*.groovy"/>

Things to note:

Logging and Troubleshooting

Be sure to have a SLF4J api/implementation jars on the classpath so that any errors are logged.
