# PmdExtension

API Documentation: | `PmdExtension`

Configuration options for the PMD plugin.

### Properties

Property | Description
`consoleOutput` | Whether or not to write PMD results to `System.out`.
`ignoreFailures` | Whether to allow the build to continue if there are warnings. Example: ignoreFailures = true
`incrementalAnalysis` | Controls whether to use incremental analysis or not. This is only supported for PMD 6.0.0 or better. See https://pmd.github.io/pmd-6.21.0/pmd_userdocs_incremental_analysis.html for more details.
`maxFailures` | Incubating The maximum number of failures to allow before stopping the build. If
`reportsDir` | The directory where reports will be generated.
`rulePriority` | The rule priority threshold; violations for rules with a lower priority will not be reported. Default value is 5, which means that all violations will be reported. This is equivalent to PMD's Ant task minimumPriority property. See the official documentation for the list of priorities.
`ruleSetConfig` | The custom rule set to be used (if any). Replaces `ruleSetFiles`, except that it does not currently support multiple rule sets. See the official documentation for how to author a rule set.
`ruleSetFiles` | The custom rule set files to be used. See the official documentation for how to author a rule set file. If you want to only use custom rule sets, you must clear `ruleSets`.
`ruleSets` | The built-in rule sets to be used. See the official list of built-in rule sets.
`sourceSets` | The source sets to be analyzed as part of the `check` and `build` tasks.
`targetJdk` | The target jdk to use with pmd, 1.3, 1.4, 1.5, 1.6, 1.7 or jsp
`toolVersion` | The version of the code quality tool to be used.

### Methods

Method | Description
`ruleSetFiles(ruleSetFiles)` | Convenience method for adding rule set files.
`ruleSets(ruleSets)` | Convenience method for adding rule sets.
