Required Parameters

Name	Type	Since	Description
outputDirectory	File	2.0	The output directory for the final HTML report. Note that this parameter is only evaluated if the goal is run directly from the command line or during the default lifecycle. If the goal is run indirectly as part of a site generation, the output directory configured in the Maven Site Plugin is used instead. User property is: project.reporting.outputDirectory.
targetDirectory	File	2.0	The output directory for the intermediate XML report. User property is: project.build.directory.

Optional Parameters

Name	Type	Since	Description
aggregate	boolean	2.2	Whether to build an aggregated report at the root, or build individual reports. Default value is: false. User property is: aggregate.
excludeRoots	File[]	2.2	The project source directories that should be excluded.
excludes	List	2.2	A list of files to exclude from checking. Can contain Ant-style wildcards and double wildcards. Note that these exclusion patterns only operate on the path of a source file relative to its source root directory. In other words, files are excluded based on their package and/or class name. If you want to exclude entire source root directories, use the parameter excludeRoots instead.
format	String	2.0	Set the output format type, in addition to the HTML report. Must be one of: "none", "csv", "xml", "txt" or the full class name of the PMD renderer to use. See the net.sourceforge.pmd.renderers package javadoc for available renderers. XML is required if the pmd:check goal is being used. Default value is: xml. User property is: format.
ignoreIdentifiers	boolean	2.5	Similar to ignoreLiterals but for identifiers; i.e., variable names, methods names, and so forth. Default value is: false. User property is: cpd.ignoreIdentifiers.
ignoreLiterals	boolean	2.5	If true, CPD ignores literal value differences when evaluating a duplicate block. This means that foo=42; and foo=43; will be seen as equivalent. You may want to run PMD with this option off to start with and then switch it on to see what it turns up. Default value is: false. User property is: cpd.ignoreLiterals.
includeTests	boolean	2.2	Run PMD on the tests. Default value is: false.
includeXmlInSite	boolean	3.0	Whether to include the xml files generated by PMD/CPD in the site. Note: In versions 2.2 - 2.7.1 the default value for this was true. This was changed in version 3.0. Default value is: false.
includes	List	2.2	A list of files to include from checking. Can contain Ant-style wildcards and double wildcards. Defaults to **\/*.java.
linkXRef	boolean	2.0	Link the violation line numbers to the source xref. Links will be created automatically if the jxr plugin is being used. Default value is: true. User property is: linkXRef.
minimumTokens	int	2.0	The minimum number of tokens that need to be duplicated before it causes a violation. Default value is: 100. User property is: minimumTokens.
outputEncoding	String	2.5	The file encoding when writing non-HTML reports. Default value is: ${project.reporting.outputEncoding}. User property is: outputEncoding.
skip	boolean	2.1	Skip the CPD report generation. Most useful on the command line via "-Dcpd.skip=true". Default value is: false. User property is: cpd.skip.
skipEmptyReport	boolean	3.1	Skip the PMD/CPD report generation if there are no violations or duplications found. Defaults to true. Default value is: true.
sourceEncoding	String	2.3	The file encoding to use when reading the Java sources. Default value is: ${project.build.sourceEncoding}. User property is: encoding.
xrefLocation	File	2.0	Location of the Xrefs to link to. Default value is: ${project.reporting.outputDirectory}/xref.
xrefTestLocation	File	2.0	Location of the Test Xrefs to link to. Default value is: ${project.reporting.outputDirectory}/xref-test.
