`configFile` | The Checkstyle configuration file to use.
`excludes` | The set of exclude patterns.
`ignoreFailures` | Specifies whether the build should break when the verifications performed by this task fail.
`includes` | The set of include patterns.
`properties` | The properties available for use in the configuration file. These are substituted into the configuration file.
`resultFile` | The file to generate the XML results to.
`source` | The source for this task, after the include and exclude patterns have been applied. Ignores source files which do not exist.

### 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. 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.
`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.
`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.
`exclude(excludeSpec)` | Adds an exclude spec. This method may be called multiple times to append new specs. 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.
`include(includeSpec)` | Adds an include spec. This method may be called multiple times to append new specs. The given closure is passed a `FileTreeElement` as its parameter. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns or specs to be included.
`include(includes)` | Adds an ANT style include pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns to be processed.
`include(includes)` | Adds an ANT style include pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns to be processed.
`include(includeSpec)` | Adds an include spec. This method may be called multiple times to append new specs. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns or specs to be included.
`source(sources)` | Adds some source to this task. The given source objects will be evaluated as for `Project.files()`.
