checkstyle:checkstyle

Note:This goal should be used as a Maven report.

Full name:

org.apache.maven.plugins:maven-checkstyle-plugin:2.4:checkstyle

Required Parameters

Name	Type	Since	Description
includes	`String`	`-`	Specifies the names filter of the source files to be used for Checkstyle. Default value is: `*/.java`.
outputDirectory	`File`	`-`	The output directory for the report. Note that this parameter is only evaluated if the goal is run directly from the command line. If the goal is run indirectly as part of a site generation, the output directory configured in Maven Site Plugin is used instead. Default value is: `${project.reporting.outputDirectory}`.
sourceDirectory	`File`	`-`	Specifies the location of the source directory to be used for Checkstyle. Default value is: `${project.build.sourceDirectory}`.

Optional Parameters

Name	Type	Since	Description

configLocation	`String`	`-`	Specifies the location of the XML configuration to use. Potential values are a filesystem path, a URL, or a classpath resource. This parameter expects that the contents of the location conform to the xml format (Checkstyle Checker module) configuration of rulesets. This parameter is resolved as resource, URL, then file. If successfully resolved, the contents of the configuration is copied into the `${project.build.directory}/checkstyle-configuration.xml` file before being passed to Checkstyle as a configuration. There are 4 predefined rulesets. `config/sun_checks.xml`: Sun Checks. `config/turbine_checks.xml`: Turbine Checks. `config/avalon_checks.xml`: Avalon Checks. `config/maven_checks.xml`: Maven Source Checks. Default value is: `config/sun_checks.xml`.
consoleOutput	`boolean`	`-`	Output errors to console. Default value is: `false`.
enableFilesSummary	`boolean`	`-`	Specifies if the Files summary should be enabled or not. Default value is: `true`.
enableRSS	`boolean`	`-`	Specifies if the RSS should be enabled or not. Default value is: `true`.
enableRulesSummary	`boolean`	`-`	Specifies if the Rules summary should be enabled or not. Default value is: `true`.
enableSeveritySummary	`boolean`	`-`	Specifies if the Severity summary should be enabled or not. Default value is: `true`.
encoding	`String`	`2.2`	The file encoding to use when reading the source files. If the property `project.build.sourceEncoding` is not set, the platform default encoding is used. Note: This parameter always overrides the property `charset` from Checkstyle's `TreeWalker` module. Default value is: `${project.build.sourceEncoding}`.
excludes	`String`	`-`	Specifies the names filter of the source files to be excluded for Checkstyle.
failsOnError	`boolean`	`-`	Specifies if the build should fail upon a violation. Default value is: `false`.

headerFile	`File`	`-`	Deprecated. Use headerLocation instead.
headerLocation	`String`	`2.0-beta-2`	Specifies the location of the License file (a.k.a. the header file) that can be used by Checkstyle to verify that source code has the correct license header. You need to use ${checkstyle.header.file} in your Checkstyle xml configuration to reference the name of this header file. For instance: `<module name="RegexpHeader"> <property name="headerFile" value="${checkstyle.header.file}"/> </module>` Default value is: `LICENSE.txt`.
includeTestSourceDirectory	`boolean`	`2.2`	Include or not the test source directory to be used for Checkstyle. Default value is: `${false}`.

packageNamesLocation	`String`	`2.0-beta-2`	Specifies the location of the package names XML to be used to configure the Checkstyle Packages. This parameter is resolved as resource, URL, then file. If resolved to a resource, or a URL, the contents of the package names XML is copied into the `${project.build.directory}/checkstyle-packagenames.xml` file before being passed to Checkstyle for loading.
propertiesFile	`File`	`-`	Deprecated. Use propertiesLocation instead.
propertiesLocation	`String`	`2.0-beta-2`	Specifies the location of the properties file. This parameter is resolved as URL, File then resource. If successfully resolved, the contents of the properties location is copied into the `${project.build.directory}/checkstyle-checker.properties` file before being passed to Checkstyle for loading. The contents of the `propertiesLocation` will be made available to Checkstyle for specifying values for parameters within the xml configuration (specified in the `configLocation` parameter).
