                                           Closure closure)

      Configures the reports to be generated by this task. The contained reports can be configured by name and closures. Example:

           checkstyleTask {
             reports {
               html {
                 destination "build/codenarc.html"

      Specified by:
        `reports` in interface `Reporting<CheckstyleReports>`
      Parameters:
        `closure` - The configuration
      Returns:
        The reports container

    - #### reports

          public CheckstyleReports reports(Action<? super CheckstyleReports> configureAction)

      Configures the reports to be generated by this task. The contained reports can be configured by name and closures. Example:

           checkstyleTask {
             reports {

    - #### run

          public void run()

    - #### getSource

          @PathSensitive(value=RELATIVE)
          public FileTree getSource()

      Returns the source for this task, after the include and exclude patterns have been applied. Ignores source files which do not exist.

      The sources for this task are relatively relocatable even though it produces output that includes absolute paths. This is a compromise made to ensure that results can be reused between different builds. The downside is that up-to-date results, or results loaded from cache can show different absolute paths than would be produced if the task was executed.

      Overrides:
        `getSource` in class `SourceTask`
      Returns:
        The source.
