Apache Maven PMD Plugin

The PMD Plugin allows you to automatically run the PMD code analysis tool on your project's source code and generate a site report with its results. It also supports the separate Copy/Paste Detector tool (or CPD) distributed with PMD.

This version of Maven PMD Plugin uses PMD 6.29.0 and requires Java 7. See Upgrading PMD at Runtime for more information.

The plugin accepts configuration parameters that can be used to customize the execution of the PMD tool.

Goals Overview

This plugin has 4 goals:

  • pmd:pmd creates a PMD site report based on the rulesets and configuration set in the plugin. It can also generate a pmd output file aside from the site report in any of the following formats: xml, csv or txt.
  • pmd:cpd generates a report for PMD's Copy/Paste Detector (CPD) tool. It can also generate a cpd results file in any of these formats: xml, csv or txt.
  • pmd:check verifies that the PMD report is empty and fails the build if it is not. This goal is executed by default when pmd:pmd is executed.
  • pmd:cpd-check verifies that the CPD report is empty and fails the build if it is not. This goal is executed by default when pmd:cpd is executed.

Upgrading Notes
