# Pmd

API Documentation: | `Pmd`

Runs a set of static code analysis rules on Java source code files and generates a report of problems found.

### Properties

Property | Description
`classpath` | Compile class path for the classes to be analyzed. The classes on this class path are used during analysis but aren't analyzed themselves. This is only well supported for PMD 5.2.1 or better.
`consoleOutput` | Whether or not to write PMD results to `System.out`.
`excludes` | The set of exclude patterns.
`ignoreFailures` | Incubating Specifies whether the build should break when the verifications performed by this task fail.
`includes` | The set of include patterns.
`incrementalAnalysis` | Controls whether to use incremental analysis or not. This is only supported for PMD 6.0.0 or better. See https://docs.pmd-code.org/pmd-doc-7.13.0/pmd_userdocs_incremental_analysis.html for more details.
`javaLauncher` | Incubating Java launcher used to start the worker process
`maxFailures` | The maximum number of failures to allow before stopping the build. Defaults to 0, which will stop the build on any failure. Values 0 and above are valid. If
`maxHeapSize` | Incubating The maximum heap size for the worker process. If unspecified, a maximum heap size will be provided by Gradle. Supports units like the command-line option `-Xmx` such as `"1g"`.
`minHeapSize` | Incubating The minimum heap size for the worker process. When unspecified, no minimum heap size is set. Supports units like the command-line option `-Xms` such as `"1g"`.
`pmdClasspath` | The class path containing the PMD library to be used.
`reports` | The reports to be generated by this task.
`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.
`rulesMinimumPriority` | Specifies the rule priority threshold.
`source` | The source for this task, after the include and exclude patterns have been applied. Ignores source files which do not exist.
`targetJdk` | The target JDK to use with PMD.
`threads` | Specifies the number of threads used by PMD.

### Methods

Method | Description
`exclude(excludeSpec)` | Adds an exclude spec. This method may be called multiple times to append new specs.The given closure is passed a `FileTreeElement` as its parameter. The closure should return true or false. Example:
`exclude(excludes)` | Adds an ANT style exclude pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.

If includes are provided, then a file must match at least one of the include patterns or specs to be included.
`reports(configureAction)` | Configures the reports to be generated by this task.
