  - ### PmdExtension

    public PmdExtension(Project project)

- ## Method Details

  - ### getRuleSetsProperty

    abstract ListProperty<String> getRuleSetsProperty()

  - ### getRuleSets

    public List<String> getRuleSets()
    The built-in rule sets to be used. See the official list of built-in rule sets. If not configured explicitly, the returned conventional value is "category/java/errorprone.xml", unless `getRuleSetConfig()` returns a non-null value or the return value of `getRuleSetFiles()` is non-empty, in which case the conventional value is an empty list.

            ruleSets = ["category/java/errorprone.xml", "category/java/bestpractices.xml"]

  - ### setRuleSets

    public void setRuleSets(List<String> ruleSets)
    The built-in rule sets to be used. See the official list of built-in rule sets.

            ruleSets = ["category/java/errorprone.xml", "category/java/bestpractices.xml"]

  - ### ruleSets

    public void ruleSets(String... ruleSets)
    Convenience method for adding rule sets.

            ruleSets "category/java/errorprone.xml", "category/java/bestpractices.xml"

    Parameters:
      `ruleSets` - the rule sets to be added

  - ### getTargetJdk

    @Deprecated public TargetJdk getTargetJdk()
    Deprecated.
    This property has no effect for PMD 5.0 and later, which infer the language version from the rule sets. Scheduled to be removed in Gradle 10.
    The target jdk to use with pmd, 1.3, 1.4, 1.5, 1.6, 1.7 or jsp

  - ### setTargetJdk

    @Deprecated public void setTargetJdk(TargetJdk targetJdk)
    Deprecated.
    This property has no effect for PMD 5.0 and later, which infer the language version from the rule sets. Scheduled to be removed in Gradle 10.
    Sets the target jdk used with pmd.
    Parameters:
      `targetJdk` - The target jdk
    Since:
      4.0

  - ### getMaxFailures

    public abstract Property<Integer> getMaxFailures()
    The maximum number of failures to allow before stopping the build. If `ignoreFailures` is set, this is ignored and no limit is enforced.
    Since:
      6.4

  - ### setTargetJdk

    @Deprecated public void setTargetJdk(Object value)
    Deprecated.
    This property has no effect for PMD 5.0 and later, which infer the language version from the rule sets. Scheduled to be removed in Gradle 10.
    Sets the target jdk used with pmd.
    Parameters:
      `value` - The value for the target jdk as defined by `TargetJdk.toVersion(Object)`

  - ### getRulesMinimumPriority

    public abstract Property<Integer> getRulesMinimumPriority()
    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.

            rulesMinimumPriority = 3

    Since:
      6.8

  - ### getRuleSetConfig

    public @Nullable TextResource getRuleSetConfig()
    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.

            ruleSetConfig = resources.text.fromFile("config/pmd/myRuleSet.xml")

    Since:
      2.2

  - ### setRuleSetConfig

    public void setRuleSetConfig(@Nullable TextResource 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.

            ruleSetConfig = resources.text.fromFile("config/pmd/myRuleSet.xml")

    Since:
      2.2

  - ### getRuleSetFiles

    public FileCollection getRuleSetFiles()
    The custom rule set files to be used. See the official documentation for how to author a rule set file.

            ruleSetFiles = files("config/pmd/myRuleSet.xml")

  - ### setRuleSetFiles

    public void setRuleSetFiles(FileCollection ruleSetFiles)
    The custom rule set files to be used. See the official documentation for how to author a rule set file. This adds to the default rule sets defined by `getRuleSets()`.

            ruleSetFiles = files("config/pmd/myRuleSets.xml")

  - ### ruleSetFiles

    public void ruleSetFiles(@Nullable Object... ruleSetFiles)
    Convenience method for adding rule set files.

            ruleSetFiles "config/pmd/myRuleSet.xml"

    public boolean isConsoleOutput()
    Whether or not to write PMD results to `System.out`.

  - ### setConsoleOutput

    public void setConsoleOutput(boolean consoleOutput)
    Whether or not to write PMD results to `System.out`.

  - ### getIncrementalAnalysis

    public abstract Property<Boolean> getIncrementalAnalysis()
    Controls whether to use incremental analysis or not. This is only supported for PMD 6.0.0 or better. See official documentation for more details.
    Since:
      5.6
